The Demial was a Kindir private icebreaker, a naval ship, commanded by Jestem in 4527 BCE on the world of Arehaz. The Demial ferried an expedition to the crash site of the Caeliar city ship Mantilis. After the expedition was assimilated by the newly formed Borg Collective, the Demial was probably commandeered and used to invade the rest of Arehaz. (ST - Destiny novel: Lost Souls)
