The part where you read exerts from HP Lovecraft and the sequences makes my cult sensors go off like a foghorn. All of the rest of it seems perfectly beneign. It's just the readings that make me think "CULT!" in the back of my mind. It seems like they're being used as a replacement for a sacred text and being used to sermonize with. If it weren't for that, this would seem much less cultish and more like a university graduation or a memorial or other secular-but-accepted-and-important ritual.
