On Halloween 1997, Ethan declared his faithfulness to Chaos while performing a ritual that invoked Janus. The spell caused those who wore costumes bought at his shop to transform into whatever they represented, causing panic and violence in Sunnydale.
In 2000, Rupert Giles answered Ethan that they had stopped being friends when the warlock started worshiping Chaos. Ethan called it religious intolerance. He then mentioned the rumors of the 314 Project, describing that the fear it caused was throwing the worlds out of balance "way beyond chaos."
Behind the scenes
- In Greco-Roman tradition, Chaos is a primordial deity that preceded the universe.
