Lilith

Lilith is the wife of the Devil. She is from the same race as him. He is the only one she loves if that feeling in demons can be called love. He is the enemy of humanity since their offspring was killed by her. She kidnaps and "eats" children to calm her anger and to steal them the life energy she needs to exist.

She has tremendous powers. She can control emotions and is often seen seducing men to steal their life energy. She does not kill them, she mates with them.

As all demon creatures, she is not immortal. She only lives many millenia, much time compared to mankind standards.
