I walked into the inn at Arinbjorn, and it triggered the starting scene for the Lighthouse quest (The Phantom of Eldberg) where the two hostile guys approach you. As I was only there to play Gwent, I *didn't* speak to Jorund after the exchange. When I went back later and did the rest of the quest, Stranger in a Strange Land didn't trigger. (And no, I hadn't already done King's Gambit).
