Voltumari (pronounced vole-too-MAR-ee) is an underwater community within the Chaska Sea, located near the Akrotirian Isles. The locathah of the city have built around a crashed aerolith, constructing their homes within and around the once-flying city. While much of the ship has been too damaged by time under the water to be usable, parts of the interior are still habitable. The people of Voltumari have intentionally cultivated corals over the aerolith, turning it into the foundations of a large reef.
Voltumari is one of the few large cities in the Chaska Sea that are welcoming of surface visitors. Some parts of the city maintain an atmosphere to ensure travelers to the city are able to breath during their stay.
