The Solumnians are a sapient insectoid species from the planet Solum: a world populated by only one city, which is built on a marshy terrain that causes it to be constantly sinking. Thus, the Solumnians spend their entire time building new layers over the abandoned sunk layers of their city. They seem to have a symbiotic relationship with the Solum Memories.
