Khaine

Khaela Mensha (lit. meaning Bloody Handed) Khaine is the Eldar God of War and is one of the last living Eldar Gods after the fall of the Eldar, although due to him being trampled on and pushed into realspace when Khorne was busy piledriving baby Slaanesh all over Eldar heaven, he's no longer "alive" in a spiritual sense and is now shattered into a bajillion pieces. These pieces make their way into the Craftworld which can be used to summon the Avatar of Khaine when the time comes, an avatar is a towering daemonic creature that makes anything it can get it's hands on shit brix. He's also the angriest God of the Eldar Pantheon, which can't really contest with the likes of Angron and Doombreed but probably comes a close.

He used to be pretty strong, but the fluff has taken a liking to murdering Avatars every chance they get.

• Killed hilariously by Marneus Calgar in the 5th ed "Space Marine" codex.
• Possessed by a Keeper of Secrets.
• Stampeded and killed by twelve carnifexes.
• Strangled(??!)/Neck snapped by Fulgrim.
• Killed by Sanguinor.

The story of the single angriest Eldar entity ever

Long ago when the Eldar were the most powerful race in the universe and they haven't raped the entire universe yet, Khaine heard from Lileath, a prophetic chick, that the Eldar will one day kill him and so Khaine decided to murder every last one of the pansies to ensure that never happens. However Isha, the mother of the Eldar, cried for the Eldar race. Then Asuryan, the Phoenix King, decided to spare the Eldar of being killed by Khaine and Isha having to see it by creating a barrier to separate mortals from gods for all eternity, ensuring the mortal Eldar would never have the chance to kill Khaine nor would Khaine get the ability to go down to the mortal realm and hack all of the Eldar down. This worked for Khaine, but not so well for Isha.

Isha missed talking to her children and so cheated through the whole barrier deal by having Vaul the Artificer (The best craftsman of the Eldar gods) make spirit stones to communicate with them. Khaine however, discovered this and cried foul on Isha and her husband Kurnous. Asuryan, not wanting to look like a biased dick, told Khaine that he could do whatever he wanted with the two which equated to eternal torture at the hands of Khaine. Given the pansiness of anything created by the Eldar, some suspect that this involved having something stuck up their orifices as Khaine enjoyed himself in a BDMS-esque fashion. Then Vaul got pissed at this and bargained with Khaine that he would make a hundred of his finest swords in a year in exchange for Isha and Kurnous' release, which he agreed to.

However, because Vaul decided to jerk off on the last day than work, he couldn't make the last sword in time and instead tried to trick Khaine out of the deal by putting one normal sword in the bunch of 99 epic swords he made, thinking that with Khaine's short attention span and his inability to count beyond 10, he won't notice and just accept the fuckheug pile of swords as is. He however didn't count on Khaine to be a total mathfag/detailfag whenever he's weaponwhoring and so Khaine fucked over Vaul and chained to him an anvil when he discovered the single normal sword amongst the bunch. Yeah, a lot of people reeeaaallly love to screw with Khaine, too bad the guy has a terrible sense of humor.

Then he murdered Eldanash, an Eldar champion, in an unspecified incident that had Asuryan him condemn to have blood eternally drip from his hands to remind him of his crime which also earned him the title "Khaela Mensha".

Then when Slaanesh was born because of the Eldar's planetary system-wide orgies, Khaine tried to fight the newly-born God and was, in the Eldar codex's words: "assaulted, defeated, and dominated", which sort of translates to being raped and forced into a buttsex-themed BDSM session with the most brutal dominatrix controlling it. Then when all seemed lost as Khaine started to roll for Anal circumference, Khorne comes out and challenged Slaanesh to a battle as he claims that Khaine is his bitch and so Slaanesh had no right to violate it, which the latter lost. And while Khorne was busy piledriving and backbreaking Slaanesh into oblivion, Khaine was in the middle of this and got shattered in a million pieces, presumably because Khorne left his axe back at his Brass Citadel and Khaine was the only available melee weapon at the time or that he made a fine object to drop Slaanesh on over and over again, and the rest is history.

And so in the end, Lileath's prophesy partly did come true in a sense. The Eldar were responsible for the birth of Slaanesh which sort of killed him, but not totally because technically he is still "alive", it's just that he's not up and about anymore like Cegorach and Isha, but having to live with the fact that he, the Eldar god of war, got beaten and buttraped by a hermaphrodite for a God is probably a fate worse than death, which was either Just As Planned by Tzeentch who was the only Chaos God who didn't directly intervene during the fall of the Eldar or Cegorach because that hilarious son of a bitch just HAD to do it for all what Khaine's done in Eldar heaven before he slipped back into the webway. Hell, for all we know, the two could have orchestrated this entire thing just to be the only 2 entities who managed to successfully screw with Khaine and get away with it.
