Dalton the Usurper

From publisher blurb: Lord Peyton has hired you as scouts as he lays siege to nearby fortress. The goal is to capture a warlord named Dalton. As the fortress falls, your liege offers a substantial bounty on the miscreant's head. The reward is too much for you to sit on the sidelines any longer and you spy an opening in the curtain wall and charge forward! This adventure setting was designed for 5th Edition AD&D for the Filbar Campaign, for four PCs at fourth level.
