Xenoblade Chronicles/Egil

When you're ready, talk to Miqol and you should be ready to go. There will be more cutscenes but it's not worth detailing it, except Shulk is doubting whether he can go on.

There's only one way to go and that's forward. A teleport on the bottom of the very top section is available to use if there's anymore sidequests for you to finish. The only downside is you can't use the warp so you have to run all the way to areas where you need to go in terms of unfinished sidequests. Anyway, you'll encounter a Mechonis Generator and a machine guarding it. Take it down and take the main teleport directly to Egil's mammoth cockpit machinery!

After a cutscene, your job is to take him down but that's not all. You have to take down three energy devices within the two minute time limit. Once it's over there will be a cutscene that will change partially everything. Dickson shoots Shulk down, revealing that he's Zanza's disciple, plus at this point, Central Factory and Agniratha is inaccessible. Lady Meyneth sacrifice her life against Zanza, coming out of their bodies and Egil makes his last stand.

With Shulk out cold, go all the way to Miqol and escape in the Junks.
