The First Church of the Unidentified Flying Object was a "saucer cult" during the Final Nights that was originally centered around the belief that humanity has been watched by beings from the "Galaxia Olympia" that issued warnings against the arms race of the Cold War. The cult gained much more adherence when a recently awoken Marauder named Leland Chin integrated their belief into his Quiet and transformed the cult into a cohesive underground net-work, now centered around the belief that the chosen of the Church will be eventually taken to Olympia and live in a perfect society. Further underlining this claim are the "Olympian techs" - in fact technomantic devices - that are given to chosen members.

In the chapter, The Earth Will Shake, from Ascension, the Church plays an important role.
