I had a thought concerning Lisanna.

Spoiler for 198:

What if Mystogan had sent Lisanna to Edolas? Like he knew that maybe the people of Edoras might try to capture her and send her to Edoras as a prisoner to keep the DS in check when they made their move. Basically hiding her in plain view and knowing that the Edoras FT would take care of her until the time is right. The people of Edoras would just think she was the Lisanna of Edoras and would just see her as any other member of Edoras FT.

If the DS didn't fight then FT was likely finished so it was a necessary sacrifice. Perhaps memories of the events of that day were altered slightly to keep it secret.
