A Champion who is visited by too many gifts of the Dark Gods eventually succumbs to madness and mutation and becomes a Spawn of Chaos. To many Northmen this is seen as a great favour, for the Champion becomes a true creature of Chaos. The Spawn is warped beyond recognition, no longer fettered by mortal concerns of self-preservation or loyalty. It operates solely via instinct. The fate of a Spawn is to die on the field of battle by axe or sword, be torn apart in the wilds by even more savage creatures, or literally ripped asunder by the Chaos energy that continues to course through its twisted body.
Mutated beyond all recognition, this Chaos Spawn is so infused with Chaotic energy that it releases the pent-up power via discharges of mystical lightning.
