The Heir System is the secondary base of operations for the Guild. While the Emperor's Hammer controls this system, they have permitted the Guild to have some of their transactions located here. There is only one planet in the Heir System, Dar.
Dar is the Heir System's only planet. All of the Smuggler's operations of The Guild are located on Dar, and in fact, the former Master Executive Polder's personal estate is located there reminiscent of the former subgroup.
The Imperial Observation base was created to monitor everything that has happened in the The Guild. Several high powered communications devices are located here, to notify the Emperor's Hammer about any possible disturbances within the Guild. The Imperial Representative housing is located there, and when the Chief Procurement Officer visits Dar, he/she will also stay at the Imperial Observation base.
The Platform Sern orbits around the planet of Dar, much like a moon. It is basically used to house any materials smugglers bring in, until a transport can be schedule to take the materials down to Dar. Most credit transactions below 20,000 credits take place on the Platform Sern. Anything above 20,000 credits will be paid on planet, by one of the members of the High Council.
The Smuggler's "Exchange" is where smuggler's will go to learn about new smuggling jobs and/or get paid for jobs they have already done. It is also a pleasant locale to socialize with fellow smugglers and merchants while listing to numerous bands.
The Smuggler's Training School is where smugglers may take courses on how the Guild works. The High Moff and Imperial Representative are in charge of managing the school.
The Guild Storehouse is where any items that aren't in immediate need are kept.
