Iorgu’s runaway pig and what happens to her
Iorgu keeps animals in Laslea, and his side quest On the Run starts when one of his pigs breaks out of her pen. He tells Coen she likes to root for apples near the bridge, so begin the search there and follow her tracks. She bolts more than once, and at one point you have to take her back from Kuno before walking her home.
Returning the pig is not the end of the quest. Coen learns she had a good reason to run, and the journal records two outcomes: Iorgu slaughters her, or Coen talks him into selling her instead.
If she is spared, she can turn up again after the sacking of Laslea in the follow-up Pig in the Middle. Follow her when she tries to lead you somewhere, and she digs up a hidden cache for Coen to take.
