From publisher blurb:
Guthe Bridge once carried traffic between Kaldor and Azadmere, the kingdom of the Khuzdul. Today, the collapsed bridge and abandoned gatehouse on the west bank are familiar landmarks to the mercantylers who ply the Silver Way, which passes the ancient bridge about half way between Naniom Bridge and Zerhun. To most folk, the abandoned ruins are a relic of a bygone age, a belief the Khuzdul are happy to encourage. Few know that the cliff alongside the gatehouse hides an underground outpost, now abandoned but still watched by the Khuzdul.
The Guthe Bridge article describes the history and current situation of the ruined bridge and outpost. It includes color GM and player maps of the area around the bridge and full descriptions and color floor plans for the levels of the underground hold and gatehouse. Information is also provided about how the Khuzdul will respond to any "uninvited guests" exploring the hold.
