I have a friend in this place that was originally from my world -- his name is Liam. Perhaps you've met him...?

[She hopes not.]

At any rate, within these past months -- ah, that is, prior to my arrival in this place -- he came into a rather large sum of power, and chose to allow me to benefit from this through a contract. His lifespan and my own are equal, and while my resistance to illness and injury remain unchanged, I no longer retain either. In the event that I were to die, I would simply be revived.

But I have never had blood forcibly removed from my body...
