Creed

Paladin tiefling/cambion 

a distant descendant of Asmodeus, Creed born under a time of great war in the hells, forced to swear oath to his faith,,  a devotion for indulgence and power, Creeds goals are determined by his internal turmoil and external pressure from his heritage and oaths. Creed is stuck in a cycle for power in order for him to remove himself from his line.

TROPES:

•  It's not winning or losing, morality, the motives of his allies, or even the glory that drives this guy so much as it is the opportunity for a good fight.
• Ambition Is Evil: Not an unusual motivation for a devil, much of Creeds motivation is driven by a desire for power and more, but power to break free of his lineage chains.
