User blog comment:WhiteSeraph/Alternate Timeline Idea That I'm Really Psyched About/@comment-3341288-20110927234023/@comment-25033299-20110928034727

UM are more like Crimson Fists, but with more hatred and a little bit of insanity thrown in... OMG IT CAME TO ME. When the Ultras on Terra discover that their legion has been utterly crushed, they immediately go to the front lines. When they meet the enemy, they are overcome by rage and want to destroy them. Khorne offers his power, and they gladly accept it. They assault ship after ship, until the Emperor becomes aware of their presence. He sadly makes the decision to send the WE and SW on them. Although the UM are down to their final dozens, they escape into te Warp, feeling betrayed by te Imperium, and festering in their hatred.
