Time...flows strangely here, I've come to gather. I doubt that you hit your head, and I do believe it to be something of this place.

When last I saw you, you were leaving Fodlan. Your people had left Dierdru in advance of the Imperial army. We fought, and you went into exile. Our conversation was brief, but you entrusted the Alliance to me in the interest of Fodlan unity.

The last thing I remember was defeating the Immaculate One, and the unification. If you have more specific questions, I will answer as fully as I am able.
