Realms of Cthulhu: Masks of Nyarlathotep
City of the Great Race
The ruined remnants of a once-mighty empire stretches beneath the landmass now known as Australia. It was once the home of the Great Race of Yith, and had been built over a much older city, populated by the horrific Flying Polyps. One of the Yithians, Kakakatak, provided the group with a rough map of important locations in the city.
