Lind had confirmed via a test subject that breakthroughs could happen for outsiders inside the arena. It was something he had struggled with but it worked.

Death was going to happen. There was no way to avoid that for the Sovereign Tiers especially.
True death was also possible but they would try to avoid it. So long as the soul survived, a new body could be constructed.

The vast majority would work behind the scenes for the shops and support staff for healing as well. There were also those that were setting up the resources for the various contests.
