If it were up to me, I'd probably kill Rend. I say that because of the fact that Eru made a brilliant character that he understands, and I think it'd do the character more justice to let him impact the character through his death than try and play a sub-par version that tries to live up to Eru. That's just my opinion, though. I think it could be interesting either way.

Also: I'm currently working on a post, and it should be up tonight, if not tomorrow.
