hmm... this sounds a lot like an rp I have been into once before and had planned to make a spin off my self (though this was on a other side I think)
was the one you were one (as it had a couple of reboots) 4 elements and outside the 4 elemets each kid had some other power like wind could read minds and fire could dream the future or something?

btw seeing it sounds alike I am also interested though I dont know if I can join as I have to see how much free time I end up having to join any other rp's
but still if I can join, which elements have yet to be taken?
