Hawaii

A small island chain in the middle of the Pacific.

History
While the Royal Guard was chased away from their homeland and Japan, the Guard docked in Hawaii, along with the U.S. Pacific Fleet. The Guard heard that the Empire was destroying convoys out to Hawaii. The Guard escorted a few more vessels into Hawaii safely. A few days later, a word came through that the Empire was to invade and occupy Hawaii. After some heavy naval engagements with cruisers, a large twin-hulled superweapon breached the defense perimeter and occupied Hawaii.
