|Customs Anti-Piracy Campaign|
The Battle of Mos Le'Harmless ensued when Rabid Jack's fleet, led by This Albatross, and accompanied by The Hangman, controlled by Mi-Gor attacked the island of Mos Le'Harmless. The united resistance of the region, gathered under pirate legend Gentleman Mallard, was similarly large, but its need to reserve troops for land combat meant that much of its fleet could not be launched to meet the oncoming warships.
Rabid Jack could not claim the island, and was eventually driven south from the island chain. Defeated and weakened, Jack's fleet fled to the Cursed Archipelago, an uninhabited island chain abundant with dark magic.
