In the tunnels of that twisted wood, whose low prodigious oaks twine groping boughs and shine dim with the phosphorescence of strange fungi, dwell the furtive and secretive Zoogs; who know many obscure secrets of the dream world and a few of the waking world, since the wood at two places touches the lands of men, though it would be disastrous to say where. Certain unexplained rumours, events, and vanishments occur among men where the Zoogs have access, and it is well that they cannot travel far outside the world of dream. But over the nearer parts of the dream world they pass freely, flitting small and brown and unseen and bearing back piquant tales to beguile the hours around their hearths in the forest they love. Most of them live in burrows, but some inhabit the trunks of the great trees; and although they live mostly on fungi it is muttered that they have also a slight taste for meat, either physical or spiritual, for certainly many dreamers have entered that wood who have not come out. Carter, however, had no fear; for he was an old dreamer and had learnt their fluttering language and made many a treaty with them; having found through their help the splendid city of Celephaïs in Ooth-Nargai beyond the Tanarian Hills, where reigns half the year the great King Kuranes, a man he had known by another name in life. Kuranes was the one soul who had been to the star-gulfs and returned free from madness.
