How do you like your evil cults?

How do you like your evil cults?

Islamic. Comes with extra child rape.

Semi secretive, enough to make the players question if any NPC they encounter belongs to it. Bonus points if they start doubting each other.

With cage-antennas.

Competing with each other, both physically and spiritually, on a regular basis.

With supple a nubile choir boys that I give the communion wine to to prepare them for holy estacy

As a cover for EVIL CAPITALISTS

Ahh...

Read that as "evil catapults". Well, why not have a cult based on worshipping sentient, malevolent siege equipment...

I like them to secretly be the good guys, but in a way that does not at all diminish the terrible evil they're doing.
