After much persuasion the ghoul consented to guide his guest inside the great wall of the Gugs' kingdom. There was one chance that Carter might be able to steal through that twilight realm of circular stone towers at an hour when the giants would be all gorged and snoring indoors, and reach the central tower with the sign of Koth upon it, which has the stairs leading up to that stone trap door in the enchanted wood. Pickman even consented to lend three ghouls to help with a tombstone lever in raising the stone door; for of ghouls the Gugs are somewhat afraid, and they often flee from their own colossal graveyards when they see them feasting there.
