They voluntarily serve creatures that want nothing more than to destroy humanity as we know it, with loyalty, with secrecy, and with voluntary breeding programs to produce more of these creatures. These creatures serve two ancient members of their race, who also want humanity destroyed. These two serve Cthulhu, a Great Old One, who would love to devour most of existence. As far as the rites...ghastly would be an understatement.
At least, this is the way the cult was back in Innsmouth. They're now claiming that they still worship the same things and have the same goals, but that they aren't quite as overt anymore. I don't buy that for a second.
Yeah, a guy...he had...hair. And...eyes. ...I can't seem to picture him. I know he was a guy, and I know he drove up in a van and that there were probably other guys in the van, but I can't tell you any details about him, or the van, or the license plate number or anything. I think they screwed with my head, Solvei.
