The Sunken Sun is a regional lowland basin where liquid-like silt rolls in slow waves beneath a copper-colored sky. Hidden volcanic vents heat the buried rock, launching sand-geysers and opening collapse-pits without warning. Verulanan caravans, ruin hunters, elemental mystics, and Arcanterran surveyors compete along a handful of fortified routes. Beneath the dunes, the Tomb of the Ash Lord rises and sinks according to the moon, revealing new chambers whenever Poreseta swells with mana.
