Well today someone broke into a good neighbor's town and as he did not have the skills or stats to enforce his own justice I offered to help. He's been robbed twice in the last week and he has supplied our town with clay and soil for virtually nothing but protection and some gear/materials we have.
After about an hour of travel I came to a series of palisaded forts and one stupid thieves HF. I should have taken a screeny of the reeks pointing to it, but after the travel and it being almost 5 a.m. I was tired and not thinking about documenting this for posterity's sake.

Those walls going up were a good idea.
There was a guy roaming around with terrible English. I decided to investigate the area and see if we could recover the stolen objects peacefully. Unfortunately, the actual items (A large chest full of seedbags, ranger gear, and a metal plow) were secured in two forts N of this one under construction. I asked the guy to open the forts so I could retrieve the items. He stated he had no key then hearthed away. He then reappeared and walked out of one of the forts. I will admit, that pissed me off. I decided I was done with this place and asked the victim what he wanted to do.
Here was our message.

(I realize now I should have just killed his HF and summoned him back on my own turf, but meh if you want to avenge scum, come get some.)

After I killed the perpetrator I asked the other guy to return the items, he refused. I let him live but told him to stay away from our area.
And the end result is one thief dead, one community warned. They get to keep the thieves spoils and this guy gets to restart with the understanding you don't fuck with someone's village. Especially if you're ultra retarded and leave your hearth fire out in the open.
