Like Prefabricated Garrison Bases the Polaris-class Prefabricated Base is a structure, prebuilt, and transported to its location of use. Unlike its inspiration, its launched all together, and lands of its own power. Though the Templars built these structures, as they wished to be prepared, only 5 were ever built because conquest was not their purpose. Four of the five were carried inside Templar II-class Star Destroyers.
