Lost River

The Lost River is an in-development biome. It is a massive, frigid  cavern system located deep under the surface.

Entrances to the Lost River can be found in both Blood Kelp Zones, the Dunes, and the Deep Grand Reef.

Description
The Lost River is generally gloomy and foggy, possessing a distinct greenish water tint that is mostly illuminated by brine pools. These pools cover almost all of the lower portions of the caverns.

The Secondary Bio-Research Facility is located in the Lost River, inside a cavern.

The Lost River is composed of five distinct areas:

Bones Field= The Bones Field is a vast cavern within the Lost River, where a massive skeleton of an unknown fauna can be seen laying. It connects to the first Blood Kelp Zone, through passages, each of them having its own flora and particular landscape, as well as the Ghost Canyon.

Ghost Canyon= The Ghost Canyon is a huge passage featuring multiple caves and tunnels branching out from one main canyon. This serves as an entrance to the Lost River from the Deep Grand Reef and connects to the Bones Field from the south. Numerous roots and luminescent-tipped branches litter the sides and bottom of the brine-filled trenches.

Ghost Forest= A large chamber lead from the main entrance of the Lost River (located in the second Blood Kelp Zone). This area is filled with whitish glowing blobs and dark brown giant Ghost Trees, and is also the starting point of the brine river. From there, the player can either go straight forward into the Bones Field, or turn right to enter the Tree Cove. Brine-falls of various sizes are present, and a smaller version of the skull found in the Bones Field can be found here.

Tree Cove= The Tree Cove is a large cavern within the Lost River. The brine river forms a large lake there, with the luminous Giant Cove Tree in its center. One end opens to the north tunnel leading to the Bones Field, and the other, a corridor, to the Inactive Lava Zone. Roots and branches grow scattered on the brine-lake and numerous Ghostrays inhabit the chamber.

Junction= The Junction is characterised by a large plateau surrounded by a ring of brine. At the top of the plateau are several smokers, and a few glowing blobs. A naturally formed bridge connects the plateau to the northern side of the cavern, towards the Ghost Forest. Brinefalls from the north and south flow into the brine here, which contains some ghost trees and roots. The Junction connects to the Bones Field to the south, the Ghost Forest to the north, the Secondary Bio-Research Facility's cavern to the east, and the Tree Cove to the west.

Future Plans

 * Carar-infected fauna will be found in abundance here.
 * More skeletons will be found, two of which are of a Reaper Leviathan and a Sea Dragon Leviathan.

Trivia

 * The Lost River is inspired by real life brine pools.
 * The skeleton in the Bones Field is suggested to be either the corpse of a Sea Dragon Leviathan or a close cousin to it.
 * Like other segmented biomes (such as the Inactive Lava Zone), the Lost River's technical data divides it into the LostRiver_TreeCove, LostRiver_BonesField and LostRiver_TreeCove again for the Ghost Canyon (this aids the AI in deciding music tracks, random events and creature behaviour).
 * The acid damage from the brine may be possible implementation/reference to the undeveloped "Pillars of Silence" biome, where enormous jets of acid dot an alien seabed.
 * The Ghost Forest was called the "Ghost Trees Chamber" before the Bones Update.
