Xenoblade Chronicles DE: Part 44: The March Through Galahad Fortress
Galahad Fortress is the stronghold of Sword Valley. Fiora is waiting inside, but also, so is Egil.
Solve some puzzles involving finding some switches and keys, and wreck any Mechon that stand in your path.
Also, take note of the battle music. It has changed, both the music when you initiate a battle, and the music that plays if the enemies does first (and that music reminds me of Devil May Cry).

At 4:30 - 5:45, I realized that being KO'd runs on a time limit. I have Party Gauge meter ready to be revived with, but neither of Shulk's allies had a smart enough AI to remind him and pick him up off the ground. If you have to wait too long for this to happen, the game just automatically forces a respawn, anyway.
I'm guess this lasts about 1 minute and 15 seconds before the respawn happens? I kept this in the video because it was kinda funny to see for so long.
Wake UP, Shulk!

The main course of action you will do here is turn off the turbines in the Ether Input Stream, then reach the elevator near there at the Preparation Bay.
That green liquid is ether. You can swim in it, but it will burn like lava, so just stay out!
