History Fanfic / RWBYDualEclipse

* AdaptationalBackstoryChange: In canon (at the time of writing), the reason for Salem being locked away was never explained upon beyond her father being a cruel JerkAss, with ''Literature/RWBYFairyTalesOfRemnant'' noting his abuse to be a combination of MaternalDeathBlameTheChild, RageAgainstTheHeavens and HeirClubForMen, with Salem tossing out messages begging for her rescue, and promising her father's kingdom as payment. In this story, [[spoiler: Ozma implies that Salem's magical potential could've surpassed her father's, so to keep her from inciting rebellion she was locked away and purposefully made ignorant of her possibilities.]]

* AdaptationalJerkass: The Remnant Gods get a bit of this added on when [[spoiler: Ozpin reveals that several of the kingdoms Salem tried to recruit in her attempt to kill the Gods refused her plea, stating she was doomed to failure. They were posthumously proven right when Destruction casually wiped Remnant clean, including the people that didn't side with Salem.]]

* MixAndMatchWeapon: Already present within RWBY's canon, though the story that preceded Dimensional Gate Screwover showed that he had upgraded Shatterpact with Huitzil parts to add plenty of features: shield units, finger-mounted guns and laser blades, and even an ice beam for incapacitating foes. His battle with Jedah Dohma wrecked several of those components, and in a later chapter he finally finds a way to restore them.

* AnAxeToGrind: Nelius's Maximov, which was picked up during his stay in the Darkstalkers world. It's noted as looking more like a decoration than an actual weapon.

* AdaptationExpansion: In canon (at the time of writing), the reason for Salem being locked away was never explained upon beyond her father being a cruel JerkAss, with ''Literature/RWBYFairyTalesOfRemnant'' noting his abuse to be a combination of MaternalDeathBlameTheChild, RageAgainstTheHeavens and HeirClubForMen. In this story, [[spoiler: Ozma implies that Salem's magical potential could've surpassed her father's, so to keep her from inciting rebellion she was locked away and purposefully made ignorant of her possibilities.]]
** Similarly, the illness that claimed Ozma's life was never elaborated upon. Here, [[spoiler: it was stated to be a new (for the time) disease that cannibalized the hearts and lungs of its victims.]]

* ArtificialLimbs: Nelius' left arm, as Epsilon gave the last vestige of her life to fuse with it to keep herself alive in the previous story. Whenever he ditches his jacket or has his gauntlets off, he keeps it hidden via a trans morphed wing in order to not scare people. Of course, Mercury has his prosthetic legs, as per canon.

* DestroyTheVillainsWeapon: Nelius shatters Melodic Cudgel, Roman's cane, in a single strike. He later breaks one of Raven's swords when she attacks him out of the blue, but she has plenty of replacements.

* MyGreatestFailure: [[spoiler: Ozpin outright states that reuniting with Salem and plunging Remnant into a ForeverWar between them was his "greatest and most foolish" mistake.]]

** Nelius has this reaction when, during an Item World trip, Mr. Egg drops a ''[[VideoGame/Disgaea5 Proto]] [[VideoGame/ZettaiHeroProject Darkdeath]]''.

* UnexpectedCharacter: In-universe, neither Nelius nor Epsilon expected to see [[VideoGame/ZettaiHeroProject the Unlosing Ranger]] show up in Remnant.

* AdaptationExpansion: In canon, the reason for Salem being locked away was never explained upon beyond her father being a cruel JerkAss. In this story, [[spoiler: Ozma implies that Salem's magical potential could've surpassed her father's, so to keep her from inciting rebellion she was locked away and purposefully made ignorant of her possibilities.]]

* FlirtatiousSmackOnTheAss: Agate delivers one to her housemate, the latter of whom implies she does this on a regular basis.

** An unintentional one: [[spoiler: Nelius bringing the Dual Diver to show off to Ozpin's group ends up landing them inside of Ozpin's Heart, where Ozma ends up spilling the beans about Salem about three to four volumes before the truth came out in canon. Notably, Ozpin is ''terrified'' that he'll be left high and dry after the truth comes out.]]

* NoMoreForMe: Qrow decides on this after sighting a certain figure out the window of the bar he's at, only for it to disappear in the time it takes for him to blink.

* WreckedWeapon: Nelius shatters Melodic Cudgel, Roman's cane, in a single strike. He later breaks one of Raven's swords when she attacks him out of the blue, but she has plenty of replacements.

** Chapter 23 has the Dual Diver state that Ruby was sent to hers... and Chapter 25 shows that [[spoiler: Cinder Fall was also sent to hers.]]

* CoverBlowingSuperpower: Nelius uses his magic only when there's nobody around to see it. However, when recounting his tale InMediasRes, Ironwood proves skeptical, at first thinking he's using either Dust or a Semblance since he doesn't quite believe Nelius yet. What really ends up blowing his cover (and thus leading to his questioning by Ozpin's group) is his inability to be properly gauged with Scrolls' Aura-Reading devices.

* ForWantOfANail: Nelius and Epsilon's presences end up changing quite a number of things.

** [[spoiler: Without Cinder's resources, the White Fang recruitment drive is notably barren, there is no battle with a stolen Atlesian Paladin (hence Blake and Sun manage to get away relatively unnoticed), and the Breach is nowhere near as nasty as it was in canon. With Torchwick tied up, Yang never meets Neo, and thus Raven's "One Save" is still available.]]

* InSpiteOfANail: Even with Nelius and Epsilon's actions, some events still play out as per canon.

** Chapter 23 shows that Ruby was sent to hers... and Chapter 25 shows that [[spoiler: Cinder Fall was also targeted.]]

** Nelius has this reaction when, during an Item World trip, Mr. Egg drops a ''Proto Darkdeath''.

* DoingResearch: Nelius is shown pretty frequently visiting Vale's library whenever he needs to look something up.

** An unintentional one: [[spoiler: Nelius bringing the Dual Diver to show off to Ozpin's group ends up landing them inside of Ozpin's Heart, where Ozma ends up spilling the beans about Salem. Notably, Ozpin is ''terrified'' that he'll be left high and dry after the truth comes out.]]
* HauntedTechnology: On more than one occasion, the Dual Diver acts on its own, pulling in other people to their own MentalWorld and even displayed a message pleading Nelius and Epsilon to save someone. Both of them begin to wonder if the Dual Diver is either becoming sentient, or is becoming a conduit for spirits. Of course, Nelius theorizes that the odd powers they were hit with in the prior story is also playing a role in this.

* InSpiteOfANail: Even with Nelius's actions, some events still play out as per canon.

* MentalWorld: The Dual Diver's Soul Diver mode acts like this, taking a person into their own soul. We see that Nelius's Mental World looks like his home Netherworld, albeit one rather devoid of life, at first. Progressing causes color and life to begin returning.

* NormalFishInATinyPond: Much like the previous story. Nelius, however, continues training, as he does ponder the possibility of other Netherworld demons potentially intercepting his message, or of others from his side of the cosmos potentially also being on Remnant. The latter ends up being true.

* SpitTake: Roman does one with some wine when he learns that his operations were disrupted again. It's also stated that some of the wine got into his nasal cavities.
* SuperMode: Belderiver, as per the prior stories. However, here we get a reveal: [[spoiler: Belderiver wasn't even supposed to exist, being Nelius' demonic powers that his boss silently sealed away after an investigative trip went wrong. Belderiver was supposed to silently bleed back into Nelius after the seal was undone, but a certain life-threatening incident triggered its appearance. His training with it has helped it to integrate over the years, slowly turning Belderiver into more of a disguise for Nelius.]]

* AdaptationExpansion: In canon, the reason for Salem being locked away was never explained upon beyond her father being a cruel JerkAss. In this story, [[spoiler: Ozma implies that Salem's magical potential could've surpassed her father's, so to keep her from inciting rebellion he had her locked away and purposefully made ignorant of her possibilities.]]

* SpannerInTheWorks: Nelius and Epsilon act as this.

* AdaptationExpansion: In canon, the reason for Salem being locked away was never explained upon beyond her father being a cruel Jerkass. In this story, [[spoiler: Ozma implies that Salem's magical potential could've surpassed her father's, so to keep her from inciting rebellion he had her locked away and purposefully made ignorant of her possibilities.]]

** In Chapter 16, [[spoiler: Qrow, Glynda, Ironwood and Nelius end up in Ozpin's heart. At first, it looks like the world of the past, and Ozma leads the group into the old tower where Salem was held, which leads to Chapter 17's events as Ozma lays out his battle against Salem.]]

* NewspaperDating: In Chapter 2, Nelius visits the local library to understand more of what Remnant is like. A newspaper sets the date as October 4th.
* NormalFishInATinyPond: Much like the previous story. Nelius, however, continues training, as he does ponder the possibility of other Netherworld demons potentially intercepting his message.

* SpitTake: Roman does one with some wine when he learns that his operations were disrupted again. It's also stated that some of the wine got into his nasal cavaties.

* TrappedInAnotherWorld: Just like the previous stories. However, with his allies in a space-worthy vessel, he plans to contact them for an extraction, since he doesn't know how to use Dimensional Gate magic. His allies, in turn, are trying to find him as well.

* EnemyWithin: [[spoiler: The chaotic powers Nelius was hit with in the prior story created a gigantic monster. When Nelius dives into his MentalWorld, it tries to usurp control. When that fails, it then becomes his EvilDoppelganger for a second try.]]

** The White Fang end up using Mountain Glenn as a forward base. Though they don't have the Paladins, the trains still work, and the tunnels do reach pretty far into Vale, giving them entrances and escape routes aplenty. RWBY and Oobleck's investigation still happens.
* MentalWorld: The Dual Diver's Soul Diver mode acts like this, taking a person into their own soul. We see that Nelius's Mental World looks like his home Netherworld, albeit one rather devoid of life, at first.

* SparedByTheAdaptation: [[spoiler: Amber is saved from having her powers drained, and a timely stop at Tukson's bookstore keeps Emerald and Mercury from killing the White Fang turncoat.]]

** In Chapter 16, [[spoiler: Qrow, Glynda, Ironwood and Nelius end up in Ozpin's heart. At first, it looks like the world of the past, and Ozma leads the group into the old tower where Salem was held.]]

** A potential one that crosses stories is the soul that was saved from the Holy Eater in Dimensional Gate Screwover. It manages to make its way back to Celestia, in time for an angelic child to find it and bring it to the others before it could potentially die.

** In Chapter 16, [[spoiler: Qrow, Glynda, Ironwood and Nelius end up in Ozpin's heart.]]

* TrappedInAnotherWorld: Just like the previous stories. However, with his allies in a space-worthy vessel, he plans to contact them for an extraction, since he doesn't know how to use Dimensional Gate magic.

** Roman and Neo are in Cinder's pocket. Roman is even placed into Atlas Custody, so that he can be in position to use the virus on the Atlas Androids.

* MixAndMatchWeapon: Already present within RWBY's canon, though the fic that preceded Dimensional Gate Screwover showed that he had upgraded Shatterpact with Huitzil parts to add plenty of features: shield units, finger-mounted guns and laser blades, and even an ice beam for incapacitating foes. His battle with Jedah Dohma wrecked several of those components, and in a later chapter he finally finds a way to restore them.

** [[spoiler: Without Cinder's resources, the White Fang recruitment drive is notably barren, there is no battle with a stolen Atlesian Paladin, and the Breach is nowhere near as nasty as it was in canon, with Yang never meeting Neo, and thus Raven's "One Save" is still available.]]
* InMediasRes: The story opens with Nelius being taken into the Vale Police Station for questioning regarding his actions. Ozpin, Glynda and Ironwood are his audience as he lays out [[HowWeGotHere how he got to Remnant, and the actions taken therein over nearly a year.]]

** Atlas is still heading efforts to assist in festival security with their droids, though it's due to the possibility that the White Fang might attack again, as they did two years prior. This still works to Cinder's advantage.

!Tropes within the Story:

* ArtificialLimbs: Nelius' left arm, as Epsilon gave the last vestige of her life to fuse with it to keep herself alive in the previous story. Whenever he ditches his jacket or has his gauntlets off, he keeps it hidden via a trans morphed wing in order to not scare people. Of course, Mercury has his prosthetic legs, as per canon.
* ChekhovsGun: A newspaper article Nelius read in chapter 2 outlined that the White Fang did try to attack the previous Vytal Festival, which was held in Atlas. This concern plays a part in why Ironwood is selected for security detail when the Breach happens.

* WreckedWeapon: Nelius shatters Melodic Cudgel, Roman's cane, in a single strike. He later breaks one of Raven's swords when she attacks him out of the blue, but she has plenty of replacements.

* ChekovsGun: A newspaper article Nelius read in chapter 2 outlined that the White Fang did try to attack the previous Vytal Festival, which was held in Atlas. This concern plays a part in why Ironwood is selected for security detail when the Breach happens.

* DarkIsNotEvil: Nelius, being a Netherworld demon and all. It puts him as a diametric opposite to the Grimm, which ends up being why they target him. His powers as Belderiver only work to cement this spot. Epsilon also counts under this.
