Though the Empire's population is by and large areligious, the most practiced religion is Expansionism, a small but outspoken group that believe the Empire has a divine right to rule Tempestas. Though seen as a crackpot cult by most, many of the Board of Directors and the higher military hierarchy are open Expansionists, and it was them who were the strongest proponents of the War of Fire. Even now, Expansionists deny that the War of Fire was unnecessary, and it's common for them to hold animosity towards the Tempestian Union for what they see as hobbling the Empire's destiny.
