On a dark night in the Sea of Storms, the Hailuga Kingdom's fleet with the blessings of the seas and the Hollyma Kingdom's fleet with the blessings of the Master of the Night declared war on the Sumerian Freedom Union. Together, they raided King's Port, a crucial port in the Sumerian Freedom Union, destroyed the Sumerian Kingdom's main fleet, the Penetration Fleet, took over King's Port, and inundated the Sumerian Freedom Union nonstop with their soldiers, thanks to their advantage on the seas.
The two kingdoms attempted to force the Sumerian Freedom Union to surrender and sign the treaty of common ownership of the magic crystal system and border trades. However, they faced fierce resistance from the Sumerian Freedom Union.
