Axel is an immortal being that is roughly 13 Billion years old, so shes as old as the universe, shes seen everything, done everything, seen Earth form, She just wants to die because she's been living for so long but can't. she's always distressed because she can't find ways to die. She made a deal with some other worldly being that granted her immortality when she was only 16 so she always looks like a 16 year old, dispite her true age which is 13 Billion years old.
