Adé sailed with this group of men for many years, honing his skills as a sailor. In 1715, he was captured by Spanish authorities, who decided to send Adéwalé to Spain, and loaded him into one of the galleons that made up their perennial treasure fleet. Thanks to a hurricane, as well as a young Welsh pirate named Edward Kenway, Adé escaped. Freeing more prisoners along the way, Adé and Edward commandeered a brigantine and set sail just in time to beat the worst of the storm. When the hurricane passed, Adé was free once more.
Adé became the quartermaster aboard Captain Kenway's ship, the Jackdaw. Operating out of Nassau for a time, they grew wealthy off their spoils and lived the lives they had always dreamed of. But Adé was a man who valued the democratic ideals of this pirate community far above the spoils they acquired while living it. And as he saw Edward Kenway fall deeper into a spiral of selfish greed and pointless glory, he wondered if there wasn't a more noble cause he might adopt to suit his ideals.
In 1716, Adé first encountered the Assassins in Tulum. He returned in 1719, where he spoke with their Mentor Ah Tabai and asked him many questions about their Brotherhood. After hearing answers that pleased him greatly, Adé joined them. For the next fifteen years, Adéwalé faithfully served the Assassins. But in time, he became increasingly troubled by memories of his past.
In 1735, Adé's ship was caught in a storm, and he washed ashore near Port-au-Prince. There, he met Bastienne Josèphe and Augustin Dieufort, whose passion drew him to the Maroon cause. In the following years, he used his skills to help rebuild the Maroon resistance in Port-au-Prince. He fled Saint Domingue in 1737 after killing the governor, Pierre, Marquis de Fayet, and returned to the Assassins.
When Adéwalé learned of the terrible earthquake that struck Saint-Domingue, he returned there to help the friends he'd left so many years ago. In the midst of the tragic loss of thousands of lives, Adé was met with two surprises: He was the father of Bastienne's son, Babatunde Josèphe, and that a charismatic and volatile Maroon leader named François Mackandal had created an Assassin Brotherhood in the region.
The Templars took advantage of the chaos to steal two artifacts from Mackandal and fled west. Adé set out after them, but not before promising that he would return to help rebuild Port-au-Prince, its Brotherhood, and his new family.
