Xenoblade Chronicles/Galahad Fortress

Be mindful like Sword Valley that this place would inaccessible after a fight with Gadolt at Mechonis Field. There's not a lot to do here.

Go forward to the opposite side to get the key and take down a room full of Mechons in a small room! When your done, go to the elevator and go down. Go to the control panel and go left and right on opposites sides to unlock the piston area control. Go around the piston area and shut it down. Go all the way, pass the control panel to the now open room. Continously take down Mechon's until you get to another elevator area.

Saving Fiora
You should battle all Mechons except for the Silver-Faced Mechon. Your team then falls down to the next area with no chance of escape. Do your best to resist Silver-Faced Mechon and attack Egil until parts of his health disappears.

A cutscene will show Fiora turning against Egil and falling off the platform, along with the team. Is this the end? Find out on the next page.
