From publisher blurb:
A Swords & Wizardry Mini-Dungeon
For 4-6 Adventurers of Levels 4-6
An orc warchief has gathered his forces near a mystical artifact capable of moving them anywhere in an instant. He must be stopped and his army routed before he gains control of the device.
The Bridgeway is part of a series of mini-dungeons designed to drop into existing adventures or campaigns. Use them as side quests or a way of getting in a quick adventure when you’re short on time.
