Death

''You got what everyone gets. You got a lifetime.'' - Death

Death is ... well... death. She's one of the seven Endless - unfathomably powerful beings which are physical personifications of cosmic forces of existence. Although she's only the second oldest (the oldest is Destiny), she's very likely the most powerful, and will be there when the very last living thing in existence dies. Even then, her job isn't done. Afterwards, she will be the only one left and eventually put the universe to rest. As she puts it, she's the one who's going to 'set up the chairs and turn off the lights.'

Also the one who gets along with living beings the best (given that she's always there at their birth and death, and has met (or will meet) every single one of them. She often takes on different forms and identities, though there are various Death gods and death personifications that claim to be her but are not (Black Racer, Black Flash, Nekron, Azraeuz, Hades, Thoth, Anubis, etc.).  She's on every planet and every point of existence, and can take different forms (often simultaneously).  She tends to like to look like a very attractive, pale young goth woman dressed in casual clothes.

Unlike most claimants of the title of 'Death', the real Death is usually rather friendly and cheerful, rather than antagonistic. One day a year, she becomes mortal and dies so that she doesn't forget the importance of her existence.
