This doesn't surprise me sadly, the Kingdom of Falderen has had a long and terrible relationship with the Yladians, as such each side as performed many atrocities to one another. In fact, the main reason Astorea was formed was due to these politics, as we, the players, carved out a piece of Falderen to give the Yladian's shelter. The best I can suggest is to advise their kind to stay within our borders, they will face nothing but persecution to the East.
