Ghost of Tsushima's first act ended with Jin rescuing his uncle, Lord Shimura, and expelling the Mongols from Castle Kaneda. Lord Sakai finds himself at an interesting crossroads heading into Act 2. In order to save his uncle, Jin was forced to rely on tactics that Lord Shimura himself finds dishonorable. Yet, without these actions, there is little doubt that Shimura, and the island of Tsushima as a whole, would have been trampled under the feet of the Mongol invaders. This struggle is at the heart of Ghost of Tsushima.
