Warmth

"I hate the dead. They have no self-control" - Sera. She is ghula - one of the extremely long-lived though not immortal flesh eaters whose lives can end in only one way - in resurrection as a hungry, ambulatory corpse who will spend the short days of its unlife rotting, eating, and infecting as many as possible. Sera compares her life to a dark comedy - trapped with an unwanted pregnancy for the past 600 years, constantly afraid that the fetus will die and go zombie in-utero, always cold and constantly running a fever like every other ghoul on the planet.
Luckily, two things in life sustain her: her joy in hunting and destroying the Dead, and the constant seeking of comfort in warmth.
