Empty Threshold

Zon-Kuthon's religious symbol.

The Empty Threshold is the temple of Zon-Kuthon in the Bonescrape neighborhood of Graydirge, a city in the nation of Geb. It is one of the largest public edifices dedicated to the Midnight Lord in the Inner Sea region, and its head priest is Ortagar Stitch-Skull.

The temple stretches deep underground and is filled with numerous architectural defects such as cramped hallways, low ceilings, uneven floors and other "features" designed to cause discomfort. It is filled with torture chambers, grisly feast halls, surgical suites, and prison cells.
