Lost River

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

Entrances to the Lost River can be found in the Blood Kelp Zones and the Dunes. In the future, the Mushroom Forest, Deep Grand Reef and the Inactive Lava Zone will serve as entrances to the Lost River. The Lost River will also play a part in the story.

Bones Field
The Bones Field is a large cavern within the Lost River, where a massive skeleton of an unknown fauna is lying. It connects through both Blood Kelp Zones, each tunnel having its own flora and particular landscape.

Tree Cove
A large cavern within the Lost River. The river forms a large lake there, with the Ghost 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. According to the concept art, Ghost Rays swim in its proximity.

Ghost Canyon
The Ghost Canyon is a large area 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.
