We shall swim out to that brooding reef in the sea and dive down through black abysses to Cyclopean and many-columned Y'ha-nthlei, and in that lair of the Deep Ones we shall dwell amidst wonder and glory for ever. A great undersea metropolis located below Devil's Reef. A swirling, lightless, effervescent scent: the deepest marine notes with bergamot, eucalyptus and foamy ambergris.
