Voltumari is an underwater community within the Chaska Sea, located near the Akrotirian Isles. The locathah of the city have built around a crashed lashunta spacefaring vessel, constructing their homes within and around the ship. While most of the technology of the ship has been too damaged by time to be usable, various systems have been repurposed to assist with life below the waves. Technology salvaged from one segment of the ship, theorized to have been used for biological experimentation, has been put to use in assisting the rapid growth of coral around Voltumari.
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.
