A vacation on New Elysium, a luxury resort located on an asteroid in the Diaspora, goes horribly wrong as the facilities malfunction and the guests and staff turn violent. The heroes must protect themselves and aid those who have remained sane, including a wealthy android tech entrepreneur who might have some information about the cause of this madness-if he can be rescured from the old mining tunnels below the resort. The heroes must find a way to stop the growing delirium, even if it means going through the guests-including a celebrated champion of the vicious sport of brutaris-who have been transformed into hideous abominations!
