Altan is the Mongol warlord who terrorises Otsuna and the main enemy of Yuna's Tales. He steals food and medicine and works with Japanese slavers. He stays hidden until Jin and Yuna strike at his allies.
Fit for the KhanFit for the Khan is the Act 3 side tale that gets you the Mongol Commander's Armor. A blacksmith's apprentice at Jogaku Temple sends you to retake four Mongol-held spots in Kamiagata, each holding a piece of armor made for Khotun Khan.In Message in Blood you clear his camp, then duel him while Yuna and his guards watch. He is a defender type, so stay patient and break his guard. He mocks Jin as a hypocrite who kills for himself. His guards attack once he falls.
The way Altan and his allies die spreads the Ghost's legend fast, and some villagers start to fear Jin. Jin and Yuna decide they are still on the right side of the line.
