This sunken city is one of the numerous ruins dating from the Age of Demons. Towers and the brass capstone of a great temple rise above the water and muck of a vast swamp. Dragon born legends tell of how the fell magic that destroyed this place millennia ago left its buildings open and full of breathable air—and treasure. Stories also tell of the Fallen Bones, a lizardfolk tribe that entered the ruins and never returned. Some believe that these lizardfolk still dwell within Mar’saval, corrupted and allied with evil troglodytes in the ruins.
This great temple of brass and granite once towered above the landscape, until at the end of a great battle it crumbled. The ground turned sodden as the sea saturated it, but though the temple sank, powerful enchantments kept the water and muck from filling it. Its minarets still poke above the waterline in places, and the lizardfolk leave offerings here for their draconic gods. Only one entrance to Mar’saval exists above ground: a tower top with a small balcony in the northern Basura Swamp. The lizardfolk revere the site but never enter it. They claim that one of their tribes, the Fallen Bones lizardfolk, took up residence in it decades ago and have since devolved into decrepitude. The other lizardfolk believe they worship a power that still dwells in the temple.
