A Wish Granted (Sterek)

I don't have it fully worked out yet, kind of just a half thought out project.

Stiles almost died it his mother's womb. Was almost never born. But Claudia had an old friend. A powerful being, that gave more than just it's life so that Stiles could be born. He doesn't know that of course. But some 'distant' relatives do, and want Stiles to come with them.
