Subrosia

Subrosia is a subterranean lava world beneath the world of Hyrule. The inhabitants, Subrosians, can access all parts of Hyrule from their land. To outsiders, this land is only accessible from Holodrum through strange portals.

The Temple of Seasons caused quite a ruckus among the Subrosians when it sank into their homeland. It is not known what used to reside where the Temple of Seasons landed.
