Path of the Vanished (B/X)

From publisher blurb: It has been 50 years since the purple-sailed ships terrorized the coasts; however, they have returned, and this time they have become more ruthless and horrifically efficient. Entire villages disappear in a single night; no survivor nor corpse has been recovered. Darker still is the purpose that drives these new Raiders as those that they captured do not appear in any of the black markets, near or far. A brave group of adventurers managed to defeat the Raiders in the past, and such a group must be summoned to follow the Path of the Vanished! Path of the Vanished is designed for characters levels 1-7 for the B/X game system.
