Available: After Silas marries another female
Character Recruited: Sophie
There are six villagers to the southwest corner of the map while Sophie, Silas' daughter will approach from the northeast. As soon as the battle starts, you'll be forced to split your forces to two, one heading west towards the fortified island in the middle of the map and another one with Silas heading north to meet up with Sophie. You need to have Silas talk to her in order to recruit her.
Once you have Sophie in your party, you have to make your way to the enemy forces. You can block the villagers from moving in the fortified area by placing an ally on the bridge. This will force them to take the longer route but you have to make quick work of the enemies in the fortified island. Later in the mission, more enemy reinforcements will appear from the forts so make sure you have allies stationed there to be able to intercept them immediately.
The boss of this map, Nichol, will not move from his fort. However, he can be captured so make sure to finish him off with Orochi's Capture command. It's recommended to save your game first before attempting to capture him. If you managed to save all the villagers or at least five of them, you'll get a Partner Seal and Energy Drop at the end of the ending scene.
