Location of the nightmare chase at the beginning of Chapter One. Full of yellow fog. Gray brick walls tower overhead above where the fog thins. The walls sag in at uncomfortable angles. Distant buildings seem domed or arched, empty, or not. Streets of broken cobblestone below, and an oily purple moon bruises the sky above.
Ray had a brief vision of this city during his nightmare in Chapter 6.
Dora saw charcoal sketches of what she thought might be this city, presumably made by Ulver Zandalus, in her psychometry vision of Dr. Losandro’s office in Chapter 22.
In Chapter 39, the party tied the appearance of the star stelae to the look and feel of this place, and believed that they were all linked somehow to Hastur.
They discovered later that same chapter that this city was being depicted in charcoal and yellow chalk on the walls of houses in Thrushmoor.
