Servants of Hastur the unspeakable, they are a race of hybrid creatures made of ordinary matter that live in interstellar space. A hybrid who is neither completely crows, nor moles, nor buzzards, nor ants, nor vampire bats, nor decomposed human beings, they can neither be fully perceived nor remembered by a sane person. They can travel through space and carry a rider, but the rider must have something capable of protecting them from the cold and vacuum of space. They can be summoned to Earth to carry out tasks or act as steeds.
Found in Bomb Shelter 4, a special conversation can happen between them and Hastur. The Golden Honey will be acquired, which prevents random encounters for a while. While Estoma and Clean Salt only eliminate encounters with enemies weaker than the party, the Golden Honey prevents all encounters, even against enemies with levels equal or higher than the party's.
In the new scenario for the PSP remake Tatsuya first encounters these demons in the first part, having never seen demons like them before. He realizes that they are servants of him and fights them.
