Eriadu Droid Foundry

The Eriadu Droid Foundry was a massive underground complex beneath Eriadu City on the planet Eriadu.

Characteristics
Only three entrances/exits existed in the foundry. The first entrance was a secret door inside the throne room of the Eriadu City Palace. The second exit was a one-way emergency elevator which led further underground to a small hangar in the side of a cliff which contained an escape shuttle. The third exit was a large room filled with elevators for transporting the factory's products to the surface.

The functions of the factory was controlled by a series of command terminals in various small control stations throughout the complex, each of which were slave-linked to a master control terminal in its own room. The standard command terminals each controlled a sector of the factory, and could adjust the speed of construction, what resources were used to make the components, and assign maintenance and guard duties to the various droids stationed in the complex.

The master control terminal was capable of overriding the commands of all the other terminals in the factory, and could be uploaded with schematics for virtually any droid, starship, or weapon which fit within the core parameters of the foundry's capabilities.

History
It is unknown who exactly built this factory in the first place. It was speculated at first to be the Confederacy of Independent Systems, but historians, using records recovered from the main computer's memory banks confirmed that it had been in existence for an unknown amount of time before the formation of the Galactic Republic.

It is likely that it was used by the supposed ancient empire that was said to have controlled Eriadu (along with much of the Outer Rim) in the years before the Republic, but no one has been able to confirm this hypothesis. In any case, the factory was discovered by the Confederacy of Independent Systems during the Clone Wars, and put into production. Unfortunately for them, however, a Republic attack on Eriadu City forced the Separatists to abandon the foundry. The Republic forces never discovered the complex.

Decades later, when Eriadu was captured by Sith forces under Darth Persia, the factory was once again discovered when Persia's apprentice, Darth Imperious, accidentally stumbled across the secret entrance in the palace. Shortly after that, guards were posted inside and the factory was put to work for the Greater Sith Empire.
