When the Horothrium started exploring space, they utilized the Si-vlade fighter to escort their colony ships. Over the centuries, this single fighter has undergone technological improvements, but has remained mostly the same in appearance. It is a light interceptor fighter that possesses light shields and quick strike weapons. It requires only one pilot. The fighter is extremely cheap to produce and with the large numbers of willing recruits to train, pilots are never in short supply. The fighters are often launched in swarms from a Vanglon Carrier and are considered expendable in most situations.
