I'll just tell you, it was Hjalmar.

No, it's on a desolate island, and you're trying to help solve the problem which makes it unlivable.

Avoiding spoilers, one of the major quests has you approach and help someone fight some monsters. In that same place there is a skeleton with a key in it for a different side quest.

After you finish fighting the monsters, a dialog cutscene triggers with the person you just helped, but there is a small window of time between the combat ending and the dialog cutscene starting when you actually loot.

I feel this in my bones

I'm curious, why left?
