Well, what if it's just literally an empty platform? The Wizard could be messing with everyone. He seems the sort for psychological games.
No, he wants a proper fight. His goal is to see who is best at fighting, not play petty tricks on us.
I think it's a pixie.
If that's the case, we'll see him when the AMF's turn on. However, I doubt 4 LA would be a good idea in this game, considering that the DR 10 is far less valuable than normal.
Pity my character can talk. What I wouldn't give to say "kill, maim, destroy" at this point.
