The Labyrinth

Beneath the hills of the Vastlands lies a maze of tunnels and caverns carved out by the underground rivers of Sirith. No one is quite certain as to how or why Argus made the rivers below the surface but some speculate it was to carry the warmth of the shallow seas to the cool rivers of the North where Kin once stood. Either way, the tunnels left behind a Labyrinth of caves in which Breim once resided. The walls are smooth and damp, cool earth chilling the air while warm underground rivers make the underground livable. In the deepest parts of the Labyrinth, seams of gemstones and precious metals run through the rock and are mined by the underground herd. There is no record of native plants in the tunnels, aside from the moss and lichen that grow beneath the skylights. Native animals to the underground are a mystery, the only evidence of undomesticated life being that of the spirit-like Kitsune that float through the unmarked tunnels and the remains of the (Giant lizard monster)'s last dinner.

Since the herd's move beneath the surface after the God's War, only about half of the tunnels were ever mapped the other half either being inaccessible or undiscovered. It's a known fact that one should never attempt to travel without a guide, as few know the paths better then them. Those that try are often end up lost, hungry, and cold or simply disappear into the darkness, only to be assumed crushed by unstable tunnels.

With the herd's return to the surface, the labyrinth has gained an eerie ghost town feel, with the tunnels being used mostly for safe underground travel, secure trade routes, and miners. The single exception to this is Isoba, which remains mostly under the surface, likely due to the cities ties to mining and smithing, though no one can be completely sure.
