The phenomenon appears only at night on sacred Aboriginal land, forming complex patterns that evolve each evening. As they journey deeper into the desert, Jed reveals he's been to the site before but cannot remember what he found—the lights cause visitors to forget their experiences there. Upon reaching the site, they discover the lights are an ancient message system connected to collective memory, capable of showing people forgotten knowledge and possible futures. The formation acts as a repository of memories from all life that has existed in the land. After experiencing profound revelations within the light formations, the trio retains only fragments of their experience, protected by pouches given by Aboriginal elders.
