Daevon is a city near Ard Carraigh, the capital of Kaedwen. It is in this general area that Geralt, Ciri and Triss were travelling when the sorceress was struck with an unfortunate case of gastritis. They tried to stop at a fort but were refused entry and advised to catch up with a caravan that had passed through the day before.
“
I's to be in Daevon in two days! the greeve yelled, shoving a short notched stick with a symbol branded into it under the knight's nose.

“
I understand. I will leave immediately. I have no choice — I have to turn back towards Daevon or Ard Carraigh.
