The Purple Rhombus is a god, always protecting it's followers, and abolishing non believers.
For strange reasons, some will have nightmares while thinking of the Purple Rhombus
Person a: Do you worship the Purple Rhombus?
Person b: No, that sounds stupid.
The Purple Rhombus would then stalk person b until they become a believer or if they refuse, the purple rhombus would hunt them down
