Strange beings - unable or unwilling to climb to the surface - lurk in the holes and in the caves which link them. They are nameless entities without discernable language or culture. They create nothing and have no apparent emotion. They exist only to eat, which they do with reckless abandon - anything living which comes into the holes is attacked and devoured unless it is strong or fast enough to escape.
The sage ¡Yi Klu of the Explorer's Cult did much work to study the beasts - until they brought about his end. His journal was taken back to the Cult's library by his assistants, where it is still very occasionally read. He describes the beasts as "somewhat like a fanged frog, somewhat like an octopus, and somewhat like a man, though with a cruel and uncaring nature all of their own."
