The Forbidden Lake is an area found inside the Darklands. It is west of Forsaken Valley. The entire area is a lake of fusion matter, the only platforms are sevreal heavily damaged docks, sunken ships, and a large island which serves as the main section of the area. The island is surrounded by a damaged fence. There is also a damaged cabin, and a crashed Scamper. The only major NPC here is GIR.
