Clara

In heaven, Clara was an artist participating in all sorts of performances -- dances, figure skating, musical theater, acting -- and she lost it all with the collapse. After a period of time spent considering her personal worth and the value of her art (at the end of the world, what is the point of a dance?) she was hired on as a performer at a mysterious, magical theater.

Clara has an instinctively kind personality and wants to bring joy to other people. She is generous with her time and energy, but not humble; she has honed her skills for far too long to deny they exist. She loves spending time with people who are skilled and talented in their own right; even braggarts are fun for her as long as they can back up their grandiose claims. Most of all, she wants art to be accessible to as many people as possible; it brings people hope, after all, and everybody deserves that. 

She is shockingly lucky.
