Each champion will come from a world and history of your own creation. Alternatively you can share a world of origin if you wish.

There isn’t too much of limit. Of course magic or items that makes a character invincible, invulnerable, or have insta win effects are not allowed. Your characters are not gods, but there is some freedom to be overpowered. I’ll probably be looking at it from character to character. For now nothing that can teleport your character out of the room, portals that can do the same, summoning, mind control, mind reading, or possession. For the sake of story, your character can have abilities like those, but they will fail each and every time in this world. Lastly, anti magic if you so choose, should be limited to specific elements (fire protection, etc) and will only protect the player character in question. 

Your characters will have woken with their own equipment. None will be provided from this strange world itself.
