From the publishers blurb:
Things not always go the way they are supposed to. It's not uncommon that an adventure, especially in a long campaign, can be greatly derailed due to a player who has got no experience, does not think an action enough or just screws things up for the fun of it. Whenever this kind of things happen, the Master must find a way to fix the situation and give the characters a way out of their trouble, and a second chance to succeed.
This adventure is designed to take characters out of trouble if they get arrested for murdering some guards or other citizens. For this kind of crimes, the guilty characters are punished with death by green slime in Glantri.
The adventure can be set in any bigger settlement in the Principalities. The characters must be held captive in a prison in that town or nearby.
