Once upon a time, there were two worlds. They were connected to each other through a number of small holes, as if the worlds were breathing through these holes. However, the holes had a tendency to close up, so there were guardians next to each one to keep them open. The guardians were called “Custos Cavum.” They took the form of seals and had large front teeth, which they used to gnaw the holes to prevent them from closing up.

Whenever a Custos Cavum felt the generation of a new hole somewhere, it fell into a deep sleep. From the body of the quietly sleeping Custos Cavum grew winged spores called “Unicuses.” These spores took flight and each flew to a new hole, where it gave rise to a new Custos Cavum.
