From PathfinderWiki

Deep within the Barrier Wall mountains of Katapesh, a network of chambers joined by winding tunnels forms a well-protected complex. Known as the Beehive, it is located on the southern road to Nex and has a number of widely known entrances.

Inhabitants have included smugglers, slavers, bandits, gnolls, dwarves, and bee-like thriae, from which the tunnels got their name. The dwarves moved out when nothing valuable was found behind the rock walls. Currently, a hive of formians inhabits the Beehive, though they mostly toil digging new tunnels underground and rarely interact with the surface.1
