The moon-beast is a frog like creature but pink in colour, webbed claws and no eyes , large mouth and pink tentacles.
Moon-beasts have no voice or eyes, yet they “see” more than most and can project their thoughts into the very minds of those they wish to communicate with. These monstrosities hail not from any physical moon, but rather from the shared satellite of all slumbering minds in the Region of Dreams beyond the wall of sleep. Here, the moon-beasts raise stone cities on the oily shores of night-black seas found upon the dark side of the dreaming moon, from which they launch long, dark galleys crewed by not-quite-human slaves that sail through the void of space down to the seas of the Dimension of Dream to seek new slaves and stranger, more sinister wares.
Moon-beasts are slavers, first and foremost. They use their spell-like abilities to curb rebellion or to quickly gain minions, but much prefer using physical and mental regimens of torment and reconditioning to break the spirit of their captives.
