Thinking on Jägers and trolls. There’s definitely a tendency for trolls – or sometimes giants, ogres, boggarts or devils – to appear in a story that goes:
- A human comes into contact with a troll, usually in a dispute over land, ie, wanting to cut wood or plough somewhere a troll is dwelling and considers his. Sometimes, though, the troll is threatening the human with less reason.
- The troll agrees to a contest or a bargain.
- The human cheats. Agreeing to split a crop on grounds of what grows overground vs. underground and then sewing wheat or potatoes depending on the troll’s choice, eating contests where they mostly hide the food in a bag, mowing contests where they put iron rods in the troll’s part of the field, etc.
- The troll not only plays fair but seems oblivious to the idea that anyone might not.
- The troll accepts his loss and goes away baffled and angry. (Or, sometimes, is tricked into killing himself.)
Othar implies something like this is the best way to catch Jägers. Draw them into a game or contest and then cheat.
