First off, the gorgon thing rocks. Especially the green smoke.
In my particular game, one character stole a lot of supplies from the character who was supposed to be the party's mentor (a supernatural blacksmith). Then, after finding out what was going on, he attempted to murder one of a group who was blackmailing the smith. The blackmailer barely made it out alive. From that, there's a chain reaction of events that leads to the blacksmith's death.
Then during a catch up session last week, the friendly party ninja tracks down the group of blackmailers, successfully kills one while she's sleeping, and nearly kills a second after a pitched battle, but can't bring herself to.
The result? The circle of vengence continues!
