Crater Edge

The Void is an area that borders the entire map of Subnautica. It currently has no use, and is not canonical to the story.

The Void is the end of the map and has a bottom at 3000 meters depth, past this there is another, seemingly infinite drop.

Adult Ghost Leviathans migrate to the Void from the Lost River, where they will act as a deterrent for wandering players going outside of the playable area.

Description
True to it's name, The Void is devoid of terrain, flora, coral, and all but one fauna species.

Fauna

 * Ghost Leviathan (unimplemented)

Future Plans

 * Ghost Leviathans are planned to spawn in the Void as a means to prevent players from wandering out of the map.

Trivia

 * Sea Dragon Leviathans, among other fauna, were planned to spawn in the Void, but this idea was scrapped.
