This is a quest given by a lord of a friendly faction. A lawless villain killed one of the quest giver's men, so he has put a bounty on the killer's head of 300 denars. If you wish, you can execute judgment and collect the bounty. Luckily, you're given a lead, the friends of the victim think the killer is hiding out with his kinsmen in a specific village. Falling to the fugitive's blade will leave you knocked out. You will recover a short while later, however you will not have another chance to attack the fugitive.
