Inactive Lava Zone

The Inactive Lava Zone is an in-development cavernous biome located deep 900 meters below the surface. It is currently the second deepest area in Subnautica.

Description
The Inactive Lava Zone is characterized by large, arching structures and walls of hardened lava. It is composed of two distinct areas and can be found at 900 to 1300 meters down, well below the limit of a Seamoth (even when equipped with a Pressure Compensator MK3) - making an upgraded Cyclops and PRAWN Suit the only vehicles to be able to navigate to and through it. The player must be extremely careful when navigating this biome, as touching the lava on the floor of the Inactive Lava Zone will result in immediate death and the temperature applies constant damage. It also contains the rare resource Kyanite, which is used in crafting some PRAWN Suit and Seamoth modules, that can only be found here.

Inactive Lava Zone Corridors= The entrances to the Inactive Lava Zone are characterized by large cavernous corridors of hardened lava opening up in the Crash Zone, Lost River, and the Deep Grand Reef. 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. Inactive Lava Zone Chamber= At the center of the Inactive Lava Zone is a large chamber, with occasional veins of lava and spires of hardened rock. Lava rivers can be found in narrow corridors around the area. A large structure called the Lava Castle can be found in the middle of the Chamber, with small, partially-collapsed volcanic domes scattered all over the floor of the Chamber itself. Lava Falls= Near the Lava Castle, There are multiple lava falls, leading directly into the Active Lava Zone. They can be found easily by following the streams of molten lava on the floor of the Chamber. Lava Pit= The Lava Pit is a large pit found on the outskirts of the main chamber. The walls of the pit are covered in large grooves, one of which acts as an entrance to the Active Lava Zone. The lighting in this area is much brighter than the surrounding areas of the Inactive Lava Zone. It resembles a volcanic dome.
