One night you were walking home when suddenly you get hit in the head and knocked unconscious... When you wake up you're tied up in a chair, hands tied behind your back, behind the back of the chair, you're surrounded by a decent amount of people in black cloaks... A cult...

The cult is chanting something quietly
