History NightmareFuel / DiabloIII

* The Blood Cult of the Temple of the Firstborn from the new release for Adventure Mode are singularly nasty. Aside from their usual business of sacrificing others, they have a habit of turning people into living roach hatcheries, turn themselves into demons, and choose only the choicest of victims for their rituals. [[spoiler:Knowing that they cannot take Nephalem in open combat, the cult steals upon them when they're asleep or unarmed before cutting open their veins for the blood they desire]]. And the guy running the show is [[spoiler:Vidian, the Lord of Envy and one of Azmodan's surviving Sin Lieutenants, who presumably wants the power of the Nephalem for himself]].

** Oh, and if the one being initiated has never committed any sins? The Order will ''make up one'' just to have an excuse to torture the poor new recruit.

--> It is said that [[SoulPower being]] [[DamagedSoul cursed]] is the [[AndIMustScream most painful way to die.]]

** Each of the Nephalem are enough to [[MookHorrorShow scare the shit out of human opponents]] if the ingame cultists are any indication, but special emphasis should go to the Necromancer whose main powers consist of A: [[NightOfTheLivingMooks summoning up the dead the serve him/her]], or B: ripping the opponent's [[BloodMagic blood]] or [[AndShowItToYou bones]] out of their body.

** The Morlu, who you fight near the end of the game in Act IV, are the ultimate fate of mortal sorcerers who make deals with demons.

* The Halls of Agony in general. These were King Leoric's old torture chambers, which saw plenty of use back when he was still alive and going insane due to Diablo's attempts to possess him and the evil whisperings of his EvilChancellor Lazarus, claiming the lives of quite a lot of people, up to and including his own queen. And that was before Maghda and her coven decided to appropriate the place for their twisted rituals. What makes things even worse is reading his journal, which captures his descent from noble king to stark raving mad step by step. The Darkening was not a fun time to live through.

* Tyrael's [[spoiler:OhCrap realization]] at the ending of ''Reaper of Souls''. [[spoiler:The Nephalem has grown too powerful, yet still suspectible of being tempted to evil. And if they do not resist, humanity is doomed. You may want to start praying that they actually resist in the future! But seeing that it's Blizzard and their history of having a boner for FallenHero, combined with their realization that Angels can be just as bad as Demons... Maybe the Sanctuary saga has a chance [[GrandFinale to end on]] [[DownerEnding an extremely bleak note...]]]]

* Demon Hunters already look scary enough with the GlowingEyesOfDoom that come with most helms, but The Shadow's Mask, part of The Shadow's Mantle set, [[HiddenEyes hides their eyes in darkness]].

* The Perilous Cave in Act V, a side dungeon that's teeming with giant maggots. Interacting with certain objects like corpses and loose stones will cause more maggots to drop from the ceiling. Oh, and there's the Maggot Broods, who spit out even more of them. [[NauseaFuel Gross!]]

* The [[spoiler:soul crucibles]] are nasty business themselves, seeing as they can [[spoiler:rip the souls out of still-living mortals, leaving their flesh for use as Malthael's minions]]. You do manage to destroy all three [[(spoiler:the one under Kasadya's control was incomplete, and crumbled when she died)]], but the implications of how many they claimed are still very nasty. You know it's fucked up when Myriam has difficulty tolerating their existence.

** Cain's description of the Butcher is disturbing for a completely different reason: [[spoiler:He describes the horrifying demonic Butcher'''''s'''''. That's right, there are ''more'' of them.]]

** Mixed with TearJerker - two boys playing around Leoric's manor implies she's seeing the ghosts of Aiden (The Dark Wanderer) and his younger brother Albrecht, Leoric's ''sons'', both of whom ended up as unwilling hosts to Diablo. Eirena's probably seeing some of the last happy moments that family had before everything literally went to hell.

'''Eirena:''' ''*cheerily*'' Never mind. They must be dead.

* In general, hearing the deathcry of your character. Special mention goes to the female wizard.
* [[spoiler:Adria's betrayal]], leading to [[spoiler:Diablo possessing Leah in one of the most horrific deaths in the entire series]] and [[spoiler:the rebirth of Diablo, the Lord of Terror himself, as the embodiment of all seven Great Evils in one being, the Prime Evil. And worse, Diablo wants to [[HellInvadesHeaven destroy the High Heavens themselves]]]]. [[HolyShitQuotient Holy Shit]] does not even begin to describe it.

* [[spoiler: The implications of Maltheil's successful release of the Black Soulstone on Sanctuary. He tooled it to absorb all demons on the plane. And humans are all half demon. No one gives a clear answer to what this means, but everyone agrees that there is no way that it won't result in the death of every human on the plane.]]

** You can find Leoric's journals as well, leading from when he arrived in Tristram up until his downfall. In one of the later ones, Leoric states that [[AndIMustScream he was aware of his madness, but powerless to stop his horrific actions.]]

* The [[spoiler:Grand Maester]]'s plan during ''The Templar Reckoning'' quest for Kormac. [[spoiler:This utter bastard plans to implement the same torturous initiation ritual that resulted in what happened to Kormac and Jondar and apply it on a grander scale, doing this to ''thousands'' of people to make them Templars]]. It's little wonder that Kormac decides there and then that [[spoiler:the Maester, and the Order itself, need to end.]]
