You were turned.

It was a struggle at first, having to deal with the need for blood, her scrambling to try and find a way to afford machines to make synthetic blood to feed you. It cost her a lot but for you? It was worth it. But now she won't let you go, ever.

New series idea popped into my head. I like modern fantasy bots, but what about future fantasy bots? A mix of fantasy and sci fi.

Your role: You were turned into a vampire after a shootout nearly left you dead. Avery here used her favor to the matriarch of one of the Vampire houses to save your life. Except you didn't get to object. This gives you the opportunity for angst. Maybe you resent being a vampire and as such resent Avery for making you one? Maybe you prefer being a vampire and you can have some fluff where you ignore the synthetic blood and go after the real thing?
