True.
Future Year 2050. Rise of Ancient Cultures..? This would give space for anything to happen within the time-span, and pick and choose sects from the past, cults, etc., or create one.
They could have certain rituals, sayings, creeds, clothing worn, weapons used.
Example; Assassin's Creed - Wore distinct outfits (At least Altair and Ezio), used hidden blades for most assassinations, and had the Creed.
It could work. Set it in a futuristic environment,and stuff in political problems, etc., that led to the 'Order's Rise."
Dystopia, sort of autonomy?
