As an Adventurer, you never know who you might be working for or what beast you'll be sent to dispatch next. There's only one thing for certain: if there's enough money or glory to be had, you're the right person for the job.
Admittedly, when the farmer came running into town claiming his crops had been torched, you hadn't anticipated a trap. By the time you realized that the farmer was luring you into a bandit ambush, they already had you captured. At least your Double Hanger kept your swords safe! Now, if you can just wiggle out of those ropes enough to grab a hilt... bandit notices and takes your swords and your Double Hanger for himself.
You really need to rethink trusting farmers.
