The Borealis was a Gazelle-class DropShip in service with Clan Ghost Bear. On 8 May 3067 it took part in the Trial of Possession dubbed Trial of Retribution, also known as the Second Naval Battle of Alshain, on the defenders' side (against attacking forces from Clan Nova Cat). In this action it was attached to the Fredasa-class WarShip Black Ghost.
Later reports described the Ghost Bear defenders having underestimated the Nova Cat attackers, and losing their entire force. Although the Ghost Bears achieved a pyrrhic victory, only a named few of their WarShips survived the battle, suggesting that the DropShips involved in the fight including the Borealis were all destroyed.
