I had a dream where I was teleported to an alternate dimension where heroes, villains, and warriors from every dimension were going to participate in a grand tournament, hosted by a surprisingly kind goddess. Several of my OCs were participating in the tournament, too.
The tournament wasn't a standard fighting tournament either. Each round had a specific goal to it, and the warriors had to achieve that goal while also fighting each other off. One of the rules, though, was that their entry fee was, more or less, their favored weapons. They had to stick them into the ground, where they would stay there until the tournament was over.
Suddenly, this god of destruction (which I keep wanting to think of as Ares... after the fact) appears and boasts that he's going to destroy this dimension using his divine spear... which he sticks into the ground, thus accidentally initiating himself into the tournament. He was pissed but he had to participate to get his spear back.
