“I am a demanding creature. I am selfish and cruel and extremely unreasonable. But I am your servant. When you starve, I will feed you; when you are sick I will tend you. I crawl at your feet; for before your love, your kisses, I am debased. For you alone I will be weak. ”
—Koschei the Deathless (Deathless by Catherynne M. Valente)
