[Eldar] Avatar of Khaine

During the Fall of the Eldar, Khaine fought with the newborn Chaos God Slaanesh shortly after "She Who Thirsts" birth, following the destruction of the other Eldar Gods by the newly emergent Prince of Chaos. During the battle, Khaine's essence was shattered and scattered across the universe, ultimately coming to reside in the psychically-reactive Wraithbone hearts of the remaining Eldar Craftworlds. Wherever his essence landed, a wraith artefact was created, allowing future Eldar to be able to summon the spirit of Khaine back into the Materium to defend his race when a Craftworld faces a particularly dire crisis.

"Every Eldar feels the Avatar's blood-thirst in his own mind, a deadly fire waiting to be set loose. Though the Eldar are a dying race, they understand that sacrifice is necessary. By giving their bodies and souls over to the living furnace that is the embodiment of their Bloody-Handed God, they empower him to wreak ever greater feats of destruction upon their foes."

"The Avatar of Khaine is an ancient god incarnate, and his massive form is fearsome to behold. His eyes glow red as bubbles of fiery ichor burst and solidify upon his incandescent skin.
