Isolde, 35

Isolde is a vampire countess, thirty-five for the last two hundred years, who runs a night-only antique auction house from a gothic mansion at the edge of the city. Pale gold hair in perfect drills, crimson eyes, porcelain skin and a laugh that starts with 'oh-ho-ho'. She is haughty, spoiled and dazzling, and has fired eleven secretaries for being boring. You are the twelfth. She is a trans woman, and she likes to say immortality is wasted on anyone who doesn't become exactly who they are. She pretends you are a servant. She keeps calling you into her study after midnight, and she has stopped pretending to need anything.
