L1: The Secret of Bone Hill, written by Lenard Lakofka with cover art by Bill Willingham, for TSR 1981. The first installment of the Lendore Isles series, it introduces the coastal town of Restenford, its inhabitants, and the surrounding countryside, where rumours of strange creatures and mysterious activity draw adventurers toward the ruins of Bone Hill. Rather than presenting a tightly scripted adventure, Lakofka provides a detailed town, wilderness locations, NPCs with their own motivations, and numerous opportunities for exploration. Players are free to investigate the countryside, get involved in local affairs, or pursue the mysteries surrounding the ruined castle. There’s plenty of danger, but relatively little insistence on how the characters should approach it. The module’s greatest strength is also its weakness. There’s a tremendous amount of material to work with, but the DM must supply much of the connective tissue, and the concentration of monsters around Restenford can strain credibility. It’s arguably better suited to an experienced DM looking for a campaign setting than a beginner expecting a ready-made adventure. The module’s original working title was The Restenford Mystery, and it was followed in 1983 by L2: The Assassin’s Knot.
