The Fromm Gang's base of operations existed on the lunar surface of Auren, a moon. This base was under the command of the Fromm Gang and comprised eight distinct tiers, each dedicated to a specific task.
This Fromm Gang installation consisted of eight tiers, with each tier serving a unique function. The lowest tier served as a prison, and above it were tiers for mining, manufacturing, and scientific research. A residential tier, a communications tier, a security tier, and, lastly, a control tier were located above these. The tiers were connected by a network of elevators that required a specific sequence of colored keys to operate. Furthermore, gun emplacements were strategically placed on the ceilings of various levels.
The droids C-3PO and R2-D2 were at one point held captive within this facility. However, they managed to break free and were subsequently saved from Auren by Thall Joben and Jord Dusat.
