Here is a brand new, stand-alone encounter for your adventures in the underworld. In this variation on the "bridge-guarding troll", your party will have to find a way to make it past Gornug, a fallen giant now deformed by his time in the underworld. Gornug's body may be twisted, but he still guards his property fiercely, and his friends below tend to agree !
The encounter is mostly based on roleplay, with the possibility of combat if things go wrong or your party is particularly belligerent. The encounter flexible and can be run with any party, although lower level parties may struggle in a straight up fight.
Have fun with the encounter !
