A blockade fleet, belonging to the Galactic Empire's Imperial Navy, established a blockade around the planet Mon Cala following the outbreak of a mutiny directed against Imperial rule. Admiral Tyrus Meori commanded the fleet, which was comprised of six Imperial II-class Star Destroyers. In the midst of combat with the Alliance Fleet alongside the Mon Cala Mercantile Fleet, the Mon Cala ship known as the Aurora Flare executed a suicide attack on the blockade's flagship, resulting in its destruction when Imperial personnel triggered the Aurora Flare's coaxium payload. This opening enabled the rebel naval forces to break through, however, Imperial vessels proceeded to obliterate The Regency situated on the surface of Mon Cala.
