Keldai

Keldai, the Ravager, the Lord of Blood, is the Arch-Demon of slaughter and wanton violence. Originally from Hirokir, Keldai's influence can be felt all over the world, wherever there is war and rage.
Demons of Keldai are violent and bestial, barely capable of any thoughts beyond a savage rage, and a glee at seeing blood spilled.
Keldai has always had some influence in the Spirit Realm, feasting on the souls of those who die in bloody massacres. Since the destruction of Ulgard Greenblood, he has exerted his influence over more and more of the Spirit Realm, and now commands hosts of Demonwraiths.
Keldai's current Mortal Champion is Nikolai Wolfhelm.
