Memrose

Memrose is one of two of the last of the Eaters, a parasitic species analagous to Vampires. They feast on the flesh of their host species, that they also live among. She is thoughtful and slow to act, and sees herself as an outsider. Where others of her kind merely struggle and hide, she imagines and fears, and comes up with ways to survive.

Memrose is like the other Eater, Zoest. She shares his goals and ambitions, but tempers them her own caution. Eventually, she's all he has to maintain his tenuous connection to those he rules over, and eventually must confront him.
