The Gug

"The Gugs, hairy and gigantic, once reared stone circles in that wood and made strange sacrifices to the Other Gods and the crawling chaos Nyarlathotep, until one night an abomination of theirs reached the ears of earth's gods and they were banished to caverns below. Only a great trap door of stone with an iron ring connects the abyss of the earth-ghouls with the enchanted wood, and this the Gugs are afraid to open because of a curse. That a mortal dreamer could traverse their cavern realm and leave by that door is inconceivable; for mortal dreamers were their former food, and they have legends of the toothsomeness of such dreamers even though banishment has restricted their diet to the ghasts, those repulsive beings which die in the light, and which live in the vaults of Zin and leap on long hind legs like kangaroos."
