The Trials are a series of three tests that the Creators, part of WICKED, created for a group of teenagers, or subjects, who are immune to the Flare. They consist of Variables designed to provoke certain Killzone patterns which WICKED will then use to attempt to create a cure for the Flare. After the subjects have passed all the Trials, WICKED will choose a final candidate to provide the final information needed to create the cure. This information is the physical composition of the Killzone, or brain, itself. It is fatal.
