History Fanfic / KeeperOfTerror

* ActionGirl: The main group, natch.
* AdultFear: Taiyang, Qrow, and Yang have it even worse here than canon. As bad as it was in canon here Ruby is Diablo's host. They are helpless to stop Diablo from corrupting Ruby after already losing her biological mother and it can get much worse from there.

* DarkIsNotEvil: Ruby dresses in black and red and [[BadPowersGoodPeople the host of the strongest Prime Evil]], yet she's a selfless heroine.

* AbusiveParent: Diablo towards [[TheWoobie Leah]], to put it ''mildly''. This revelation solidifies Ruby's decision to be the AntiAntiChrist.

** At one point, Diablo tries to tempt Ruby into giving in with a promise of power. It doesn't work. [[spoiler:And even then Diablo is this without even trying [[VillainsNeverLie (he himself]] [[BrutallyHonest states this)]] when Ruby is starting to have demonic features (scales and starting to have a tail) and [[SuperpoweredEvilSide a darker mental personality]].]]

* DarkIsNotEvil: Ruby dresses in black and red and [[BadPowersGoodPeople the host of the strongest Prime Evil]], yet she's a selfess heroine.

* PrimalFear: Diablo's powers are based on this. It's most basic manifestation is an aura of terror, but it also comes in the flavors of fire and lightning for more direct offense.

** Chapter 17 expands more about this. [[spoiler:Remnant is [[EarthAllAlong Sanctuary]] thousands of years after the events of ''VideoGame/DiabloIII''. [[UnwittingInstagatorOfDoom Tyrael]] threw the Black Soulstone thinking it was heading to another dimension but in reality, sent it thousands of years in advance and was [[DetonationMoon the cause of the Moon's destruction]]. Still no JokerImmunity though.]]

* HeroicWillpower: One of the factors keeping Diablo from fulling possessing Ruby. But he's chipping away at it, and Ruby knows that willpower alone won't be enough in the long run.

* ColdBloodedTorture: [[spoiler:Andariel]] subjects the owner of a bookstore to this to get what [[spoiler:she]] wants from him.

* NoodleIncident: Anyone who has played ''Reaper of Souls'' knows that Malthael broke the Black Soulstone and absorbed the shards in order to fight the Nephalem, and after his defeat Diablo escaped, more powerful than ever. Somehow, the Angiris Council managed to reconstruct the Black Soulstone and recapture Diablo, but how they did it is unexplained.
