Shoot.
Any elf I try to think of, you've already written about them.
I'll be looking through my Silmarillion to find some elves, though. :] I'll get back to you if I find any obscure elves you've missed.

Or what about like, Aragorn? He's around a lot of elves, and I don't think you've done a lot with him, have you? I always love stories of Aragorn when he's younger.
