Inactive Lava Zone

The Inactive Lava Zone Corridor are mini-biomes which links the Lost River and Inactive Lava Zone together. There is only one known in the game, it is via the Tree Cove. The other entrance is located in the Mountains Corridor which leads directly to the Inactive Lava Zone and then to the Lava Castle.

Description
The Inactive Lava Zone Corridors are characterized by large cavernous corridors of hardened lava. Veins of active lava can be found regularly, sometimes ejecting molten boulders. The Corridors continue well below all other biomes and converge into a central chamber. Resources such as Nickel Ore and Crystalline Sulfur are frequent in this biome which come in useful in the fabrication of certain vehicle upgrades.
