WMG: Destiny

The Vex and the Darkness

The Universe of Destiny is the result of temporal tampering. The story goes like this: In a future not longer achievable to the city, the Traveler, and their Guardians, a great federation came to exist between the four races: Humanity, the Hive, the Cabal, and the Fallen (or Eliksni). Each race had its part in a utopian society The houses of the fallen acted in defense of the alliance, The cabal worked diligently to build and craft the wonders of this utopian age, the Hive, sharing a single mind even at impossible distances held the federation together, and humanity was on the cutting edge of science and technology. This union of the greatest of each race would eventually culminate in one of the greatest scientific achievements outside of traveling into another universe: Time Sliding. For eons time travel had been possible, but the process was inefficient and unreliable, Time sliding was simple and wasted little energy. But with the ease of Time Sliding came a new challenge, how do you prevent its abuse? And thus the Vex came to be. Each race contributed to the new Guardians of time, The fallen gave them an unyielding sense of duty the Cabal forged tough cases to hold the vast energies of each unit. The hive linked their minds together in vast networks and the Humans installed within each one a Time slider device and the capability of entering the Garden, an extra-temporal space that would act a home for all Vex. The final gift was the light. through a process of distillation of their own genetic structures, the races had managed to create a biological version of the light granted by the Traveler, though there were imperfections. To combat the corruption if the light, every vex was granted a fixed lifecycle, beginning and ending with the dismantling of a unit. The programmes were to follow this highest of laws without question, without hesitation. There was one Programme however that resisted, instead of dismantling older Vex units it hid them in a distant corner of the Garden away from it masters and fellow Vex. The corruption escaped the vex units it was trapped in and began to infect even new units with a growing instability until even the central Mind of the program lost itself. It began to hate, hate its situation, hate the orders it was given and hate those that had made it less than perfect. It needed power, and so it would used the very nature of the Garden to achieve it, leaving the garden and returning to before it left, combining with a past version of itself in an unending feedback loop, each time growing more powerful, and unstable. (It is during the early part of this plan that it becomes the Heart of the black Garden and the player is sent to destroy it, but this doesn't change a thing because it exists outside of the normal progression of time[action-reaction]). Once strong enough the Mind leaves the Garden, as the Darkness, into a time before its targets could challenge it. The plan was simple enough, destroy itís creators from within. The first target was the hive, and to this end first Ornyx and them Crota were created. Built in the form of the Hive, but meant to disrupt the Singular mind (the destruction of both may lead to the hive mind reforming). The two would set themselves up as Gods of the now chaotic hordes. The Fallen were easy enough, their rigid social structure could be destroyed or corrupted to meet the needs of the Darkness. It was around this time that it began to hunt the traveler, the one thing in the universe that was still a threat to it. Darkness fell too late on the Cabal to corrupt the species in its entirety, but was content with just pushing them towards someone who needed to die. And to this end they began to aim them towards the final piece of the federation. It reach the Sol system far too late to prevent the rise of humanity into the golden age, but was more than enough destroy their (relatively) primitive means of defence using the Hive, Fallen, Cabal and even the Vex of itís own programme. It tried to corrupt humans attempting to flee to distant colony worlds, but before it could finish the Traveler intervened, launching a Darkness specific EMP style pulse that froze the Awoken in a state of semi corruption, and freed the Hive and Fallen from the Darkness, as well as forcing the Dark Vex back into the Garden.During itís final moments before falling into slumber to recharge itís spent energies the Traveler connected with its future self in the age of the federation to wam it about the tretery of the Darkness. The federation them ordered the Vex Programs under their command to hunt down the Darkness in the past and repair what damage they could. The Vex in the game are not the Dark Vex but rather the Vex sent to repair the damage. They cannot understand the universe that now exists, people that did not exist in the original timeline are prominent players and the Awoken are a race of walking anomalies as far as they are concerned. The Exo Stranger is from the federationís Future and was tasked with overseeing the vex in their current mission, but she has no way to alter the parameters of their mission to fix the constant aggression of literally everything. T He ruins on Venus and Mars are what the history files say should be there at this point in history, so the Vex are trying to repair and ERROR 404: landmark not found (The ruins on Mercury are not however and were created by the Darkness to be a seat of power and were abandoned when the Traveler forced the Dark Vex back into the Garden. Any further Vex presence of Mercury is them attempting to remove the structures.) Their attacks on other races is similar to an antivirus software attempting to remove corrupted/unwanted files from a computerís hard drive.

Real life people that are now Guardians.
Guardians are resurrected from the dead. There's no stated time limit, just that they need to be able to wield the light. So, let's make a list of all the real people, dead or alive, that are now Guardians (and their class).
  • George Washington, Titan
  • Staff Sergeant Max Fightmaster, Titan
  • Summer Glau, Warlock
  • Simo Hšyhš, Hunter
    • Vasily Zaytsev, Hunter

The triangular ships hinted at are Jovian

The player won't actually fight the Darkness directly
If a fight with the Darkness makes it into the story line then the Traveler will fight the Darkness directly with the player either fighting an avatar or fighting a key battle against an underling who has the means to skew the result of this conflict. After all, the darkness displayed in the intro seems like a giant solar system sized cloud of black goo. A later encounter lends credence to this portrayal of black goo. Its not like the player could just run around shooting at the sky or expect their gun to hurt an entity bigger than the Sun. The encounter on the Moon and later may lend credence to this theory. Matti23

The stars will go out
When a fight with the Darkness arrives the stars will seem to go out. The Darkness is a huge cloud of black goo so if it heads for Earth it may definitely have this effect on the sky. Matti23

The Darkness isn't a single entity but a group of Godlike beings
On the moon mission the Hive are said to be waiting for their Gods to return. Crota is said to have taken the moon. There's no mention of a wave of invaders coming after or before the darkness.

Humanity will turn out to have been the villain
The fall may have been caused by humanity having done something terrible, causing the other races to attack.

The Traveler may be the final boss
If the story ever gets wrapped up it may turn out that the Traveler only saved humanity to further its own nefarious goals or that humanity is one of the villains of the game, the Traveler being either a powerful human construct or an ally. Matti23
  • It's definitely hinted that the Traveler might not be as good as it is thought to be. Read the Black Garden entry http://destinynews.net/destinys-mysteries/ . It seems also that there may be more to the Vex than crazy murder bots.

There are people living inside the Traveler
People or aliens may operate the Traveler like a spaceship or habitat rather than the Traveler itself being a single entity (Thats no moon... It's a space station.) This leads into...

The Traveler's residents will appear as a faction in the future

The Traveler is related to Cocoon in Final Fantasy XIII
Could be another similar construct located on a distant world (with more friendly Fal'Cie responsible for the Traveler's powers).

The Traveler is responsible for humanityís fall from grace
This could be one of three ways:
  • Directly: the traveler itself destroyed human civilization.
  • Indirectly: The traveler led those who would destroy human civilization here on purpose.
  • Accidently: The traveler led those who would destroy manís civilization here, but not on purpose.
    • Confirmed, the villains followed the Traveler to Earth and it is stated that they are long-standing enemies.

The Traveler is Durandal after the closing of the universe
He escaped to a parallel timeline, and decided he would protect humanity.
  • Alternatively, it's a parallel Durandal who never left the Marathon. Considering the Marathon is Deimos, and the Traveler is the size of a small moon.
  • Or it's Durandal at the end of Marathon 2, where ten thousand years later, he returns to Earth in a Jjaro dreadnought to say hi.

The Security Officer from Marathon will appear
What was the name Durandal gave him, as the universe closed? Destiny

Destiny is set in the aftermath of the Human-Forerunner war
The Traveler could be a Forerunner Warrior-Servant who has taken a liking to humanity - doesn't that sphere look an awful lot like a Cryptum?
  • But humanity didn't return to the stars until 100,000 years or so after the firing of the Halos, and they knew nothing of their previous empire. Unless perhaps you mean a second Human-Forerunner war that may arise thanks to the events of Halo 4.

A major questline will be to track down and neutralize someone trying to enter the Traveler and deactivate it.
Because that big of object, floating that low above the ground? If it shuts off, it is going to fall unless the Guardians stop it from doing so. It's practically inevitable that someone will try. Of course, that paves the way for major secrets to be revealed about the Traveler, not least of which is locating a suitable door.

The Traveler is sentient, and will be helping you throughout your travels.
The E3 demo revealed an AI ally, named Ghost (voiced by Peter Dinklage) who tries to help you. ("Tries" in that during the demo he turns on the lights, which alerts all the baddies). WMGs have been built on less.

The Traveler came from the Sun
This poem from Alpha Lupi, an ARG website launched by bungie, associates the sun with hope and returning strength, the same themes associated with the Traveler:

The Blaze sits inside a nest of little worlds, still too distant to share its heat but plainly staring out at you. A face emerges, drawn from plasmas and radiation...

There must be meanings in its roar.

You listen hard and carefully, and sometimes a lucid melody seems to rise out of random noise, pulling your mind into moments where it seems possible that answers are about o be revealed. Joy builds, and the first hope in ages transforms you.

It seems important, even critical, to tell every star from here to the black between the galaxies that you are strong again.

There will be an AI called Joyeuse
In The Song of Roland, the inscription on the blade of the sword Cortana read; "My name is Cortana, of the same steel and temper as Joyeuse and Durendal". Bungie's last two sci-fi game series had a Durandal and a Cortana respectively, so they're probably going to complete the set sooner or later and it may as well be in Destiny.

The Location of Joyeuse
In regards to the WMG above about the existence of Joyeuse. Bungie has released information about the location of Charlemagne's Vault on Mars. In the Destiny universe, Charlemagne was (maybe even still is) a warmind, an advanced AI. Joyeuse may in fact be a subroutine or fragment of Charlemagne that is retrieved from Charlemagne's vault.

The Guardians were raised from the dead
It is heavily implied through the Grimoire cards and gear descriptions that the Guardians are in fact long dead beings that were resurrected by the Traveler's Ghost drones. And then there's this piece of NPC dialogue from the Tower
  • Confirmed, in the beta. You start the game with your character getting resurrected by a Ghost.

The Guardians are Einherjar
As mentioned before, the Guardians were soldiers during the Golden Age of Humanity, presumably killed in the Collapse when "The Darkness" closed in on the Traveller, and just as presumably Humanity's best during the fall of humanity's empire, thus prime candidates for Valhalla (Or in this case, The Tower). Had Ghost been given a female voice as opposed to male, there would be a very obvious allusion to a Valkyrie here (But alas). One of the major plot-points brought up early on by The Speaker is the coming return of the Darkness, which The Speaker says they will not survive unless something is done - What event could this logically be, being their prophesied final battle? Look no further than Ragnarok.

The Traveler is actually the missing moon of Lh'owon
After humans and S'pft'kr allied at the end of Marathon 2, the other, more advanced races hinted at decided to attack humanity in order to screw over the S'phft'kr. The S'pht'kr and their flying moon base were able to prevent the total destruction of humanity but not before humans were on the brink of extinction, leaving them no choice but to leave the it there to protect humanity until they could rebuild.

Later content will involve the new expansion of humanity and their allies, as well as introducing new (possibly playable) allies and threats
  • The fight against the Darkness is far from over and expansion further out into the stars offers the possibility of other races and aliens joining the fight for either side
The Vex, with all of their interdimensional warping, will make a grievous mistake that will prove their undoing.
  • What are the player characters called? Guardians. What is the subtitle of the next series installment in Halo? Guardians. The two versions of humanity will band together, trading the powers of Light for direly needed military personnel and materiel. Cue John-117 becoming the most Badass Titan in existence. Alternatively, a Hunter instead, as suggested by his cloak in the Halo 5 reveal trailer.

The game is a standalone universe separate from previous bungie titles like Marathon and Halo

The Traveler isn't entirely benevolent and it's previous acts of benevolence are all a part of a larger gambit
  • What better way to get humanity on your side than to first improve their lot in life, then heroically sacrifice itself to the point of barely functioning? After that, humanity and its allies are gonna be willing to protect it at any cost (a human shield, if you'll excuse the pun), and fight back the Darkness for it, perhaps enabling the Traveler to commit greater atrocities when it's restored. After all, we only have the word of agents of the Traveler and its previous actions (Which can easily be interpreted as protecting itself by creating an army) to support the idea that Light Is Good and Dark Is Evil.
    • From a pragmatic standpoint, the Traveler deliberately intended to use humanity as an army, because it could not fend off the Darkness itself, and its arrival into the Solar System brought the Darkness following it. However, if the Darkness had found humanity before the Traveler did, humanity would instantly be driven to extinction with no chance to resist. Thus, a forced alliance brought ruin to both parties, but prevented outright destruction. The Traveler gave humanity the tools to resist Darkness, enabling protection for both the species and the Traveler.

Humanity isn't the only race the Traveler's taken an interest in.
All of the enemies are linked to the Darkness somehow: the Hive and the Vex worship it and the Cabal are implied to be running from it. The only one without a clear connection are the Fallen. Now, the Fallen used to have a powerful and advanced empire, but then they fell, splitting into multiple disparate noble houses, a shadow of their former glory. Sound familiar? They mirror the human Golden Age, the Collapse, and the Dark Age ("a thousand kings rose and fell then"), only without the Traveler hanging around to start the City Age.

It's stated that the Darkness hunts the Traveler wherever it goes. Maybe the Traveler uplifted the Fallen the same way it did to humanity, only when the Darkness came around and toppled their civilization, the Traveler didn't sacrifice itself for them. Instead it fled the Darkness, and much later it encountered humanity and the process repeated. The difference is, for whatever reason, the Traveler decided to rescue the last remnants of human civilization, whereas it simply abandoned the Fallen to their fates.

For that matter, maybe the Cabal were uplifted too, but the size of their empire meant that when the Darkness came around and apparently razed their homeworld it didn't affect them nearly as badly.

The Exo Stranger works for the Nine
  • She's not a Guardian, and says that she was not forged in Light. Your Ghost says that the last place the Light touches is the Reef. Beyond the asteroid belt where the Reef is are the Jovian worlds, all of the gas giants, where the Nine rule. The Stranger is working for someone else and didn't come to Venus alone when she first met you, and is continuously updating someone on your status, plus her weapon is said to have technology beyond anything the City has built.
    • Specifically, it has parts that "shouldn't exist yet". The magazine contains a temporal anomaly that sometimes retcons missed shots as not having fired.

The Traveler will be revealed to actually be a planetoid sized Ghost
  • Its triangular parts having been scattered into space to act similarly to the way it did on Earth, to uplift and gift a species with its light (a many lights in the darkness kind of thing) - a later plot will involve uniting with those uplifted species and restoring the Traveler to its Ghost state.

Rasputin will take the Travellers Place
  • He's doing something with those planetary defences. He's fought the darkness and still lives. If the traveller is killed outright he may step up.

Rasputin is the Vex
  • Or at least a direct ancestor. It's a Warmind, which is part of a Solar System scale distrubuted network. It is orders of magnitude more complex than a human being, and it is one of the few things that survived the Collapse intact. Using the data it gathered from the darkness, it evolves over the millenia. It learns to create mobile units that are part of it's own network. It discovers the Black Garden and the Darkness at it's heart, and uses the fact that it is outside time to ensure it's own evolution. That's why the Vex are at war with the Cabal on Mars.

The Guardian you control isn't a random long dead person...
  • You were one of the warriors fighting during the Collapse that the Traveller took notice of... The Ghost supresses your memories of what you once were. Part of the future plot is that your memories start to reassert themselves, and through them you learn what went on during that time. The Exo Stranger also knew you were due to be resurrected, and made sure to keep an eye on you. She doesn't know you don't have the right memories, thats why she seems cryptic.

The Exo Stranger is from the future
  • Her rifle is impossibly advanced for the current timeline, and the reason she was not birthed in the light is that the Traveller is long gone in her native timeline.

The Exo Stranger is from the distant past
  • The Exos were created to fight a long-forgotten war before the collapse, but the current ones can't remember a bit of it. The Stranger is part of a group that has been kicking around the entire time, and she predates the creation of Ghosts and Guardians. This also explains her use of technology the City considers impossibly advanced, the group simply kept developing their equipment while the rest of civilization was reduced to scavenging old tech.

The Traveler is Madoka Kaname's Soul Gem
  • And the Darkness is an even-more-powerful Kriemhild Gretchen. When Madoka Kaname made her contract in the final timeline, a Soul Gem was still created. This Soul Gem survived Madoka's sacrifice, and gradually regained sentience, becoming the Traveler. Being who she is, Madoka decided to help people some more.
  • But then, the Darkness came. While Madoka's canonical contract wish prevented her from becoming a witch, multiverse theory suggests that there would be a world where she didn't, and Homura's time loops continued. This would result in the continued buildup of Madoka's potential, until the point where, when she finally made a contract and became a witch, the resultant incarnation of Kriemhild Gretchen would be powerful enough to kill Homura before she could reset the timeline, unstoppably destroy the Earth, and continue to grow... until it became powerful enough to consume and leave the universe itself. (And kill/consume the Incubators if they tried to stop it.) This incarnation of Kriemhild Gretchen became the Darkness, and only the power of Madoka's Soul Gem and her final wish could defeat it.
  • As such, Kriemhild Gretchen reached across dimensions to place her Witch Kiss on innumerable followers (as well as possibly sending in Familiars), and drove them to attack Madoka's Soul Gem.
  • In the great battles the Speaker talks about, Madoka's Soul Gem was forced to use her powers, depleting her reserve of mana and thus weakening the amount of area she was able to protect, as well as her consciousness. As such, Kriemhild Gretchen is able to act more and more openly, resulting in "the Darkness".
  • This means that things are about to go From Bad to Worse - Madoka's Soul Gem is already very corrupted (look at the Traveler; does it look all that bright for a supposed being of Light?) and it's only going to get darker. When it corrupts all the way... either the universe will have to face two super powerful Kriemhild Gretchens, or her wish will override it and it will simply disappear, resulting in the loss of the "Traveler"'s protection, the loss of the Guardians, and the victory of Kriemhild Gretchen.

The Sword of Crota wasn't destroyed
The sword was instead rigged to return to Crota's side and wake him up if the Hive's enemies ever grew strong enough to vanquish the Princes. Nice job breaking it, Hero!
  • Given that Crota bites it in the aptly titled Crota's End raid (at the hands of no more than 6 Guardians, at that), it's likely that this is no longer an issue.

The Vex are fighting the Guardians via Time Travel.
Everytime you redo a stage at a higher difficulty, via the daily, weekly, or Nightfall mode; that's the Vex doing it over again. They win any reality you lose.
  • It's stated that Aetheon and the Vault of Glass are eternal, because they are constantly rebuilding each other into the timeline. Similar to Garland and Chaos.

The Gardener was not the Traveller
Rasputin mentions that the Gardener was defeated by IT. IT was not the Darkness. IT was the Traveller. The Gardener was the architect of the Black Garden, and the Vex (although much simpler than the current versions) were her creation.

However she did not 'shrug' and allow the Vex to be destroyed when she was defeated. She managed to badly damage the Traveller by cracking it's outer layer and taking some sort of organ (The Heart) from it, and placed it in the Black Garden to be protected by her servants. Unfortunately, the Traveller was still able to defeat her, and used the last of it's power to move to Earth. The Vex began to evolve without the Gardener to guide them, and were corrupted by the Heart. They are unable to give the Heart back to the Traveller because they still have the last order from the Gardener hardwired into them, they cannot release the Heart from the Garden. But they worship it, and it wants to return to the Traveller. They are kind of stuck in the logic problem.

When you destroy the Heart's guards, it allows the Traveller to reabsorb the mising piece.

Destiny takes place in the same universe as The Bartimaeus Trilogy.
The Traveler and Darkness are both massively powerful spirits that are many ranks above even Ramuthra, the huge spirit that was summoned in the first book. The magicians who summoned them? The Hive too over the moon and turned it into a pentacle in order to summon the Darkness while The Speaker did the same for the Traveler over a hundred years ago when it first popped up. Ghosts are mid-ranked Imps or Foliots also summoned by The Speaker and charged with bringing back people who died during the Collapse as Guardians.

The Darkness is the Traveler, Rasputin, or both from a Bad Future.
The entries in the Grimoire, particularly the Ghost fragments, seem to have a running theme that minions of the Darkness claim the Traveler and the Darkness are Not So Different. There's also emphasis on idea that both Ghosts and Guardians can fall to the Darkness, and even wield it the same as they do the Light. The Exo Stranger has a weapon that shouldn't exist yet, and her Ghost Fragment seems to imply that she's experienced the same events multiple times.

All of this is leading up to the revelation that the universe is locked in a Stable Time Loop: The Darkness chases the Traveler, pursuing it to Earth, where it makes its last stand. There's a reason for that: here is where the possible timelines converge, which is also why the Vex are so interested in our solar system. Hence the added symbolism of the Collapse; it's a reference to the waveform collapse in quantum mechanics and the many-worlds hypothesis. There are are a number of possibilities here: one, supported by concept art and Grimoire entries that associate the Black Garden with the interior of a spherical body, is that the Heart of the Black Garden was actually inside the Traveler, and is the beginning of the Traveler's transformation into the Darkness; the Traveler and the Darkness are the same entity at different points in time, hence their Not So Different nature and the equivalency of Light and Dark. By destroying it, you've temporarily prevented the Traveler from falling and becoming the Darkness. Now think a minute: who told you to destroy the Heart?

The Exo Stranger is originally from an alternate future, and she and her as-of-yet-only-hinted-at allies have been trying to break the Stable Time Loop, having failed in multiple timelines already. Hence her apparent foreknowledge of events, and her statement that "A side should be taken, even if it's the wrong one." - she only cares about breaking the cycle, whether by healing and protecting the Traveler or by destroying it.

However, that still doesn't explain WHY the traveler becomes the Darkness. So here's a possibility: Rasputin. The entries surrounding Rasputin and his actions in the game imply that he's started to admire the Darkness, and is in the process of trying to distribute himself across as much of the solar system as possible, devouring other A.I.s in the process, in order to become as solitary and unkillable as the Darkness. It's possible that at some point he takes over or combines with the Traveler (or the Gardener, as he likes to call it/her - another bit linking the Traveler to the Black Garden) and in doing so becomes the Darkness. Then, in line with Rasputin's desire to survive beyond even the universe (as stated in a Grimoire entry pertaining to him), he uses his newfound god-like power to go back in time/to another timeline (the two concepts being one and the same in this case) in order to ensure that this future comes to pass, granting him immortality across all of space and time.

The Vault of Glass is the Vex's attempt to understand the Heart of the Garden.
The Vex worship the Heart as a god because they can't understand it and see no other logical alternative to dealing with it. But consider that the Vault of Glass is presided over by Atheon, a word that can be translated to "atheist", and that one of the weapons you can get from completing the raid is called the Mythoclast, which itself translates to "destroyer or debunker of myths". And once the Vex are able to understand the Heart, they plan to use their in-development ontological weaponry to destroy it — the Heart is currently more powerful than the Vex, and they simply can't allow that.

Crota really is as powerful as Hive get.
The epithet "Son of Oryx" is somewhat accurate, but "Oryx" in Hive scripture refers to the Darkness itself, which simply uplifted a random (or not) Knight for whatever reason, as opposed to an even more powerful being. As Crota is the most recent result of the Darkness' most direct blessing, he is the most powerful of the Hive. Those that the Darkness uplifted before are older and thus better know how to use their power, but at the same time, that power has waned as the centuries ticked by.
  • HOOOOOO-BOY WAS I WRONG! Turns out Oryx is actually a guy and served as Crota's literal father. Whoops. Good news is that he's almost certainly the strongest Hive we'll ever see.

Future Expansions
Post House Of Wolves, these will include such things as
  • Perspective Flip missions where you play as one of the enemies, either in the present or as part of a historical flashback.
  • New categories of weapons.
  • The ability to read Grimoire cards without having to leave the game and go the website.
  • Hybrid classes like in Mass Effect. (Hunter+Warlock, Hunter+Titan, Warlock+Titan, eventually Hunter+Warlock+Titan).
  • Race specific abilities and perks.
  • Missions set in the City itself.
  • Story missions where Guardians have to permanently kill rogue Guardians.
  • More about the history between the arrival of the Traveller and the present day.
  • Arenas set in full out zero gravity.
  • An expansion focused on the Cabal. (The main story focuses on the Vex, the Dark Below on the Hive and House of Wolves on the Fallen, so it would be a logical next step)

We've already "seen" characters with the new subclasses.
In The Taken King, the Vanguard has declared that the Guardians need to venture out into the wild and reclaim the lost arts (a fancy in-story explanation to the new subclasses). Thing is, we may already have (indirectly) encountered past Guardians of these subclasses: Thalor, a Titan, was once a legendary champion of the Crucible (until Dredgen Yor and his Thorn put an end to that, at least.) He used to wear the Titan Mark called Thalor's Golden Maul. Now what, exactly, is a maul?

Oryx is not actually a creature of the Hive.
The only thing in common with his design and Hive are the three eyed motif. He is called Oryx, The Taken King. The Hive are an entire race that was Taken and twisted until it suited Oryx's purposes, something akin to Mass Effect Reapers re-purposing conquered races like Protheans into Collectors. Oryx however is waging a war to exterminate all life he deems weak while conqueroring those he deems worthy. This is why the Hive worship him as a God, because he created them.

He is what the Cabal are running from, and he is interested in the Cabal because of their strength and numbers. Given time, and experimentation, The Cabal will become Hive-like or maybe even something new that Oryx will replace the Hive with(after all, even his "son" has failed to take an insignificant blue ball in the boonies of the Milky Way). Oryx is turning his attention to Earth because defeating Crota has piqued his interest in humanity. Alternatively he is being directed by The Darkness itsself to finish off the Traveller and its scattered light.

The Cabal on Mars may be the last "free" Cabal alive.
Along with the above point, The Cabal on Mars are completely unaware of WHY they were sent to this system, they just followed orders and made a base. Of all the four antagonistic alien races, the Cabal are the only ones organized enough and have the military hardware to invade the rest of Sol, but they don't. Cause they were not told to. Assuming any of the high command on Mars were informed of their true mission, they probably died on the trip out to Sol. Their real mission was to find the Traveler and acquire its light so they might fight Oryx.

Another thing to remember, The Traveller was FOUND on Mars. It would explain why they spend so much time tearing apart the ruins of Martian cities, They are looking for ANY clue as to why their great Emperor/Empress would bother with Sol. Apparently it is so far from the other Cabal territories they cannot send messages back and forth(assuming Oryx has not Taken the whole empire by now)
