The Lost River is an in-development biome. It is a massive, frigid^[1] 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. The Lost River will also play a part in the story.^[2]

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 Lost River is composed of four distinct areas:

Ghost Trees Chamber

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.

Tree Cove

The Tree Cove is a large cavern within the Lost River. The brine river forms a large lake there, with the luminous Cove Tree in its center.^[3]^[4] One end opens to the north tunnel leading to the Bones Field, and the other a corridor to the Inactive Lava Zone.

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, and also 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.
