Golh, an aquatic world, existed in the Outer Rim Territories as a part of the Golh system. This planet was the property of the Hydrospeare Corporation, which utilized it as a location to experiment with aquatic projects, most often military vehicles and weaponry designed for use in water.
A team of Rebel agents from Sedrian successfully infiltrated Golh and launched a surprise attack on a testing crew. Dr. Sere Lure, the overseeing designer, was the only one who got away; since then, she has suggested using any other aquatic planet for testing purposes.
