A remnant of the autonomous AI fleets developed by the TriTachyon Corporation. Illegal under Domain (and Hegemony) law, and an abomination to the Church of Galactic Redemption, the First AI War saw these creations purged from the Sector. At least that is how the official histories tell it.
The Radiant battleship was an outrageous blue-sky design created by some naval architecture unit given special indulgence by a TriTach VP's bloated grandiosity. Both the official and existing unofficial histories of the First AI War never mention this class of ship ever being produced because an integrated phase skimmer could never be stable on a ship of such size. Surely it would explode into an infinity of curiously whorled short-lived child-dimensions upon initiation of the first skip.
Nonetheless, here it is.
The Radiant is a rare, powerful Remnant battleship. They are normally only found commanding Remnant Ordos, the largest battle fleets of the Remnants, in systems with red beacons.
Like other Remnant ships, the Automated Ship skill is needed to recover and effectively use Radiants.
