This is the first tale of the second act. It will start as soon as the "Shadow of the Samurai" tale is completed. You won't be able to use the fast-travel option until you complete it.
With Lord Shimura freed, we can take the fight to the Mongols and reclaim Castle Shimura, the strategic heart of Tsushima Island that has recently fallen to Khotun Khan.
My uncle and I will ride ahead to scout the battlefield. Together, we will plot our moves to reclaim Castle Shimura - and our home.
Rewards:
1. Speak with Yuna / Walk to the keep with Yuna
This tale starts the next morning, in the garden where you fought Ryuzo. Yuna will inform you that your uncle wants to talk to you and after a while you will be able to head to the castle.
2. Speak with Lord Shimura in the keep
Enter the castle and talk to your uncle. You will talk about your recent "exploits" and about Yuna's future. He'll agree to help her get to mainland if she helps him get his castle back.
3. Optional: Speak with your allies
Before you go to the stables, you can talk to your allies: Lady Masako, Sensei Ishikawa and Kenji and Taka (they are together). You will find them all outside the castle.
4. Ready your horse at the stables / Speak with Yuna
Go to the stable and talks to Yuna. When you tell her what your uncle told you, she won't be happy about it. After a while, Lord Shimura will come to the stables and you and him will ride for reconnaissance.
5. Mount your horse / Wait for the gates to open / Ride with Lord Shimura / Clear the way to the lighthouse
Follow your uncle. When you get to the Old Togo rice fields, you'll come across a Mongol patrol. Help your uncle to kill them all.
6. Ride with Lord Shimura / Defeat the Mongols
Follow your uncle to Fort Ito and kill the Mongols guarding the gate. Then the gate will open and more enemies will run out, which of course you also have to get rid of.
7. Reach the Mongol alarm / Defeat the Mongols guarding the alarm / Speak with Lord Shimura
When you enter the fort, you will hear the sound of an alarm.
You must get to the other side of the fort and kill all the Mongols who guard the alarm. When you do that, approach your uncle and he will inform you that you must move quickly back to the front gate.
8. Reach the front gate with Lord Shimura / Defeat the Mongols / Speak with Yuna
Run back to the front gate. When you get there, Yuna will join you, and she will get rid of most Mongols who will try to attack you with an explosive arrow. Kill those who survive.
Then you will be able to talk to each other and you will decide to go to the lighthouse to light it and thus give some hope to people of Tsushima and send a message to Khan.
9. Travel to the lighthouse
Go to the lighthouse. When you reach the foot of the lighthouse, Lord Shimura will make a promise to Yuna that he will help her get out of the island once she convinces the people of Yarikawa to help you defeat the Mongols.
10. Climb the lighthouse with Lord Shimura / Reignite the lighthouse
Go to the top of the lighthouse and light it. Lord Shimura will tell you what your next steps should be, and then you will automatically get back to the fort.
11. Listen to the woman / Speak with the warrior monk
When you get down, a woman will come up to you and inform you that one of the released prisoners - a warrior monk - wants to talk to you. You'll find him a few steps away. Come up and talk to him. His name is Norio, and he'll tell you his story.
12. Follow Norio
Follow Norio and he'll show you the pit where he and the other prisoners were held.
13. Exit the fort's northern gate
Then leave the fort throught the north gate, which is the one near where the alarm was. You'll talk to Norio for a moment and then this tale will be over. Some new quests will appear on the map and in your journal.
