Dominion Priest

A Priestess of the Zyrrak Dominion, and one of their lead bloodletters, Nemesis fights purely for the hunt like her people are known for. Carrying a slender ceremonial dagger as her weapon, and aiming for arteries for the most visually pleasing end to her enemies. She only accepts the highest level bounties, and only when they say "dead or alive", because while she is already inclined to cause bloodshed, she is bound to her blade.

Her blade being as advanced as you would expect from the Zyrrak Dominion, is linked with her at the deepest level, her feeding and the blades being connected. As she battles, her blade feeds on the blood of her opponents. As this happens her speed and strength escalate till there is no more left to battle. This being the reason she is almost always on the job, no need to sleep, no need to feed, just to fight.
