Find Constantin at the Palace Walkthrough
Constantin has left your squad, but Captain Vasco is now forced to help you – accept his services.
Follow the marker and find Siora, the daughter of the local clan leader, near the palace. Following the cutscene, she will automatically get into your group. You’ll have to temporarily remove Kurt or Vasco. Make your choice and then go inside and go upstairs. Talk to Constantin about everything to start a new quest.
