1) Near Winded, there are only large trees. Perhaps it's worth simply approaching them and taking a look around?
2) Besides the elementals, is there definitely nothing else that appears there?
3) Are you already tired of picking up chemical potions from the mages? As they say in the tavern: "Many novice wizards believe that if they have mastered a couple of simple spells, then they can easily mix potions afterward. Corpses of mages who overestimated their knowledge of chemistry are still found in the area."
Maybe I missed something about the island? Maybe I needed to do something?
