I'll keep him...it? in check, and it would serve as a sort of punishment for the loosers anyway so...
I can come up with a few of the challenges/training areas from some nightmares that I have. Let's I've got a floating island surrounded by a giant staircase made out of floating focks and a giant waterfall that is terrorized by waves of Giant mosquitos the size of a large horse, and whose surface is made up of a giant forest/antnest that is populated by little insight out goblin creatures the size of four year olds that attack in hoards.
An oil rig type building that is situated in the middle of an endless ocean that extends several dozen floors into the ocean and is populated by demon/zombies.
And a giant shopping mall complex...a lot more dangerous than it seems, believe me.
If you think that your creations can survive in these things feel free to post them.
Welcome one and All to the Jesters Carnival, where the prizes are greater than your wildest dreams, but the nightmares here shall silence you before you can even scream.
