Mahanaya is a large desert planet located within the Oma-Tol Sector of the Tuuros Galaxy and is the homeworld of the ancient Mahanayan race, and the seat of power of the Spiritualist Dominion of Mahanaya. Largely difficult to traverse on the surface, Mahanaya is in fact a cavernous planet that houses a vivid subterranean ecosystem containing vast freshwater sources. Mahanaya is the home to the ancient spiritualist architecture and culture of the Mahanayans, and is a source of intrigue and historical concern to much of the Tuuros Galaxy.
Very little is known of Mahanaya's history; home to a culture more ancient than that of some of the eldest spacefaring cultures within Tuuros, only vague mentions of Mahanaya survive from historical documentation spanning back to one hundred and forty thousand years ago. Incomplete and damaged over time, these records mention the identity of the Mahanayans, indicating them as an ancient culture perhaps of a similar antiquity to Tuurosian precursors.
