Hello mods, I have missed you! I am here to ask about the fighting rings since it is Championship Time.

Thor has been involved since he arrived and would definitely want to try to be involved in the fights (and try to win, ofc). 1. How hard is it to find out what's going on/get his name in the contest, 2. how hard are the fights likely to be, and 3. what (if any) are the prizes for whoever wins the contest??
