All the events will be explained when the event starts on a journal, but so you can get a slight heads up. The in the race portion, your character will be racing anothers to a finishline of some sort. In all these trials, they're going to cater to the characters themselves, and when the event starts there will be a journal detailing the race conditions for each line up.
For now we're just gathering up the 16 people that will be a part of this with their characte sheet submissions. When that is together. The tournament will start. Their will be constant updates. No one will be in the dark.
Well, the last trial is an actual battle. But everything is a conflict. For example, just because its a race, doesn't mean you wouldn't be trying to incompacitate your opponent; trying to stop them by whatever means nessecary to make sure your character crossed the finish line first. Does that help?
Oh do you wanna perhaps join up and watch the tournament? You don't really need to participate, but at the end of each round there will be a journal up for a week to drop opinions on the contestant work where people can help sway my vote for one or the other.
Just incase you're interested in the theme enough to watch.
