Underneath Orsholon City is reported to be a vast network of tunnels and passages, believed to be the remains of a sewer system from before The Cataclysm. As far as they have been explored, they extend far beyond the city walls, although many of the passages have collapsed and been closed off.

[Missing image · WA ID 1277330 — “It is belileved that before The Cataclysm, these tunnels were part of “]It is belileved that before The Cataclysm, these tunnels were part of a vast sewer network for a city that stood in the location where Orsholon City now stands. The tunnels all have a slope toward the south, in the direction of the Riqaba River. They branch out from a large main tunnel, and after the Cataclysm, many sought shelter in the tunnels. Since the building of Orsholon City, however, the majority of the entrances to the tunnels have been sealed off, and it is believed that armorys and vaults are now in the tunnels, protected by the Royal Guard Of Orsholon.
