History Recap / Destiny2SeasonOfTheSeraph

* BladeOnAStick: This season introduces a new Solar Glaive, Judgment of Kelgorath. The most interesting thing about it is that it's made by Hakke, a foundry that specializes in modern day firearm lookalikes in the ''Destiny'' setting.

** Häkke is another Human group touched by the Darkness, as they used Clarity Control to help construct Revision Zero. This also reveals that the foundry itself is much, ''much'' older than they seem; previously, only Daito was confirmed to be a survivor of the Golden Age.

* XanatosGambit: It becomes evident that Xivu Arath's goal is to use the Warsat network to cause mass destruction, and through Hive Sword Logic her power would exponentially increase allowing them to bring forth a massive Hive army through the ascended plane. Initially everyone involved assumed they just needed to take control of the network before Eramis can but realize that such destruction in any form would empower Xivu Arath even if turned against the Hive and House Salvation. For half of the season this forced a stalemate, they couldn't let Eramis have control of the Warsats but couldn't use those same Warsats to fend them off. [[TakeAThirdOption The ultimate answer]] had Rasputin deciding to [[NoMacguffinNoWinner destroy the Warsat network itself]] and [[HeroicSacrifice himself along with it]], to ensure it couldn't be used against humanity.

** Rasputin, on the other hand, plays it straight. The climax of Seraph comes with the revelation that the only way to ensure the warsats aren't used to destroy the Traveler is for Rasputin to destroy everything related to Warmind tech - including himself. He pulls off a HeroicSacrifice with Ana's help, saving the Traveler and denying Eramis a chance at getting revenge.

* SequelHook: After his HeroicSacrifice, Rasputin left a message to the player Guardian affirming the existence of a city on Neptune and that it possesses something called "The Veil" ([[ArcWords a major term]] in the lore regarding the Darkness). This leads the story into the Lightfall expansion.

* YouHaveOutlivedYourUsefulness: The Witness no longer considers the House of Salvation a viable asset to their plans, and to that end uses Xivu Arath to wipe them out and turn them into Wrathborn and Scorn.

* HeroicSacrifice: The epilogue of ''Seraph'' has Rasputin willingly allowing himself and all warsats (and any other tech related to him) to be destroyed and rendered inoperable, so that the Traveler isn't destroyed and Xivu Arath's manifestation is denied.

* CerebusRetcon: Archangel/Archie, the robot dog locked deep within the Seraph Station, initially appears to be a funny little EasterEgg for destroying [[GottaCollectEmAll all 50 security drones]] with Revision Zero as well as Bungie's take on the "you can pet the dog" meme. The epilogue ruins the humor entirely by revealing that Archie was also supposed to be part of Rasputin's submind system, making him ''another'' TragicKeepsake after the "Persona" lorebook was already revealed to exist in-universe as Rasputin's parting gift.

* KillSat: The season is mostly centered around helping Rasputin regain control of the Warsat network so that he may help against Xivu Arath's incoming threat, though the Vanguard eventually settles for a stalemate once they realize that using the Warsats to inflict mass casualty on the Hive and Scorn plays into Xivu Arath's plan to manifest herself on Earth through the same ritual that laid waste to the Cabal homeworld. When Eramis hijacks the network to aim at the Traveler in the season finale, we're treated to a close look of a Warsat's internal gun, which resembles a scaled up Sleeper Simulant. Eramis's nefarious plan to shoot down the Traveler fails when Rasputin uploads himself to the Warsat network and destroys it at the cost of his entire existence.

* KilledOffForReal: Variation. The Clovis AI still exists on Europa, but copied a portion of itself to be housed in the Experimental Exo Frame to assist with restoring Rasputin. When this is achieved, Clovis tries to demand his daughters keep him around, but Ana denies him and instead has the newly-remade Rasputin enter the frame and delete that partition of Clovis permanently, so as to make room for the Warmind. It's treated as a death and a big decision on Ana's part, signifying how much she cares for Rasputin and how she's hit her breaking point with her smarmy, arrogant, self-centered grandfather still trying to enforce his tyranny when everyone else has already moved on.

* MagikarpPower: The focal exotic weapon for the season, Revision Zero, found in the Seraph Shield mission, is a pulse rifle with innate anti-barrier qualities and a SecondaryFire with high powered sniper rounds. The gun on initial acquirement is a little underwhelming as the legendary stasis pulse rifle Disparity released at the same time is, literally in lore, a simplified version of the base gun that doesn't have the exotic qualities but nonetheless has better starting stats without taking up the exotic slot. But Revision Zero was designed with an eye towards build crafting (only the fifth exotic with that quality after Osteo Striga and three class glaives). Further weekly runs of the Seraph Shield would provide the next tier of the "Hunter's Trace" perk that provides a general improvement across all stats while allowing you to customize different perks to your playstyle, turning it from a sluggish base weapon into a more finely tuned, lethal gun. Additionally, each upgrade tier lessens the number of critical hits needed to build up one sniper round from the alt mode.

* SwissArmyWeapon: Revision Zero, a pulse rifle stated in promotional material to have multiple firing configurations and room for ''several'' catalysts to maximize its number of use cases.
