Great Inagua is an island of the Bahamas, which was home to a sizable plantation owned and operated by the French Templar Julien du Casse up until 1715. In September of that year, in order to claim El Arca del Maestro for Nassau's defenses, the pirate Edward Kenway assassinated du Casse and subsequently took ownership of the island, including a manor overlooking the cove.
Over the next several years, Kenway invested heavily in the development of a settlement on the island, improving the docks, beachfront, and the manor itself. Following the British retaking of Nassau in 1718, Great Inagua became the new base for the remaining pirates of the West Indies.
In October 1722, before leaving the West Indies to return to England with his daughter, Edward gifted the island to the Assassins, who had elected to abandon their base in Tulum in the face of repeated Templar attacks.
