The Alashan city control center functioned as the primary building in the underground city located in Alashan. This structure was responsible for generating the power that fueled the entire city; any harm inflicted upon its internal components negatively impacted the city's technological infrastructure. In addition to its role as a general energy provider, the control center also supplied the energy required by the Guardian of Forever, the entity responsible for protecting the entire city.
Approximately during 0 ABY, the Rebel protagonists, Luke Skywalker together with Leia Organa, managed to get inside the control center and inflict critical damage, which resulted in a city-wide power outage and the destruction of the Guardian of Forever. Nevertheless, after the Rebels had departed from the planet, power was restored to the massive complex, suggesting a form of self-repair capability.
