The Star Destroyer of Tiber Saxon, an Imperial I-class Star Destroyer, belonged to Tiber Saxon, who held the position of Governor of Mandalore. During a mission to Mandalore executed by Clan Wren, Clan Kryze, and various members of the Rebel Alliance, the Star Destroyer was stationed outside Sundari, the capital city. The mission's objective was to obliterate the Duchess, an arc generator housed inside the AT-DP Arc Cannon Prototype. The Star Destroyer was ultimately annihilated by the mission's conclusion, alongside "the Duchess," the AT-DP Arc Cannon Prototype, and Saxon himself, with the ship plummeting to the ground close to Sundari's base.
