Under Legatus Nael van Damus, the Vllth Imperial Legion constructed Castrum Novum to house the lunar transmitter used to call down the satellite Dalamud. Legatus Gaius van Baelsar and his XIVth Legion subsequently confiscated the facility. They have used it as military stronghold since, and expanded upon the mining and refining capacities of the place to produce munitions.
