Sovereign End is the Act 3 trophy for the final push on the Khan. It unlocks in Eternal Blue Sky, the assault on Port Izumi in Jogaku, Kamiagata.
Finish Heart of the Jito, then speak with Yuna at Jogaku Temple. Infiltrate Port Izumi, find the Khan from a high point and see the fight through to the end of the tale.
Talk to all four allies at the temple first. It is optional but adds context before the battle.
You duel Khotun Khan a second time while poisoned. The Khan uses all four stances, and you finish him in this fight.
