The Dreoinin are a bat-like race that clings to the cliff-like edges of the bottomless pit in H6. Although they have a high birth-rate, their population grows slowly if at all, due to their naturally quarrelsome nature. Many a fight between dreonin ends with the loser being thrown to the bottom of the bottomless pit, as their vestigial wings do not actually allow them to fly. They are an evil (-1) race with a fondness towards cruelty for cruelty's sake, especially when directed towards those they consider inferior, which is practically everyone and everything.

The Bottomless Secrets Society's goal is to journey ever deeper into the bottomless pit in which they live, seeking out its dark secrets.
