|Behind the scenes|
Lacuna is a pass through the mountains of Tantalus, north of the Great Wall, which can only be reached by air. It connects on to the Well of Souls. The pass curves slightly northwards and has a number of small, shallow ponds along its length.

Able Ryder flew through the area on a great leonopteryx (if allied with the Na'vi) or in a Dragon Assault Ship (if allied with the RDA) on his way to the Well of Souls. It is impossible to land in this area.
