What are some good celestial names for a celestial elf who is half native Indian? Character name?

No suggestions -- no specific suggestions. Just some encouragement. Elves in fiction and legend and lore alike tend to have whatever name they are given. Dobby in Harry Potter has a name we are more likely to associate with a horse while Gildas, in LoTR for example appears to be named after a rather dour fifth-century cleric. Everyone who has read the exuberantly supernatural African Classic My Life in the Bush of Ghosts by Amos Tutuola agrees that the Television-handed Ghost is a BRILLIANT invention. I'm really bringing it up just to say, don't sweat her name, just work her and her name and you will find that any of the names you mention can be perfect for her.
