He's the first mate on the Jackdaw, which is Edward Kenway's pirate ship. Freedom Cry actually takes place 15 years after AC4, reveals Ubisoft. The Season Pass will contain single-player add-ons.
It's not all 'map pack' nonsense with Ubisoft's plans for Black Flag, as they intend a number of additional adventures in single-player as well as more customisation.
As of now the Season Pass contains the following:
▪ Freedom Cry: Born a slave, Adewale found freedom as a pirate aboard the Jackdaw as Captain Edward Kenway’s second-in-command. Fifteen years later, Adewale has become a trained assassin and finds himself shipwrecked in Saint-Domingue with no weapon nor crew, starting a new adventure of his own.
▪ The Exclusive Kraken Ship Pack – Only available to Season Pass owners, this pack includes personalization elements for the Jackdaw
▪ New ways to personalize the player’s pirate experience – Additional single player missions, weapons, skins, and collectibles
▪ More Multiplayer Mayhem – Unlock new characters for an even more expansive multiplayer experience
