The ship was named in memory of Jedi Master Belth Allusis, who died while leading the final stand to defend the Bothawui planetary shield at the Second Battle of Bothawui during the Great Galactic War.
The Allusis was the setting for a battle between Republic, Sith, and Mandalorian forces after Clan Varad hijacked the ship out of the Republic shipyards at Fondor.
