Sorry if this has been answered before, but what are the rules concerning death of a character in the arena? Or at all, for that matter? I only have one character which I've been using since I started RPing as a teenager, and in my previous RP forum there used to be a 21-day re-spawning rule. Is there something similar here?

Not at all. You can even have the same character in several fights at once, given it makes sense, such as the fight's happening at different points in time.
