Darth Decimus, mastermind of the Corellian invasion and leader of the Empire's planetary forces, has established his central command in the former offices of the planet's Trade Tariff Service. Moff Tarandon recommended the building's use on the grounds that its function was now obsolete, and that enemy forces would likely ignore it in favor of attacking the Legislature Building.
Darth Decimus wasted no time transforming the former government office into an Imperial fortress. The structure's main entrance is under heavy guard and the only access to Decimus himself is via a single secure turbolift. The few Corellian bureaucrats in the building when Imperial forces arrived either pledged themselves to the planet's new government, or fled their offices via any route possible.
