Subrosia is a location from The Legend of Zelda: Oracle of Seasons. Subrosia is a subterranean lava world located beneath Holodrum. Subrosia is connected to Holodrum through a number of vortex-like "portals". The fire-resistant inhabitants, Subrosians, can access all parts of Holodrum from their land via portals found in Subrosia. The only way for outsiders to enter is by means of one of the well hidden portals.
