They gave up, I cleared the dungeon with Lorelei and her 1 stack. If that female archer hadn't arrived, it would have been a surrender on turn 117, but instead, I started to gain momentum from the second turn. There were 3 accessible castles and another one further away, which I could see from the map, with a treasure and a crown. My opponent had a better position, and it seems he took advantage of it, which led to a loss in the castle (3). Thanks for the game.
I didn't play one important turn correctly, and the result was a loss that shouldn't have happened. Thanks for the game.
