My Dear Friend,
I had a feeling we wouldn't have a chance to talk before Vizima, so I leave you this message. I know there's much we both wish to say, but there will come a time for that later. In any case, a letter is no place to broach topics of such importance to us both.
So, why I write you now: you have something waiting for you at the royal palace in Vizima. Consider it a gift from Emhyr and myself. You can pick it up at your leisure after your audience with him. When you exit the throne room, simply follow the covered walkway in the courtyard, turning right at the corner, then take the first door on your left. You'll be inside a chamber with a fireplace. Take the door in the back right to the adjoining room. There, under the window, you'll find the chest with your gift. But in case these directions prove too complicated for you, I'm certain the chamberlain would not hesitate to lead you there himself. Expert tracker that you are, however, I expect you'll manage.
Your friend, Yennefer
