One of the original D&D classics, The Isle of Dread is a hex crawl wilderness adventure. It focuses on surviving primitive beasts, dinosaurs, and pirates while uncovering the mystery of the island's inland city, where a great treasure awaits.
CM3 is part of a series, CM1-CM9, from 1984-1987, for upper-level ("Companion" tier) PCs. Sabre River offers a mix of tactical encounters with challenging monsters, a region-wide mysterious curse which needs to be investigated, its cause understood, an especially interesting volcano setting for one set of encounters, and great treasure hordes. Although part of the CM series and potentially part of a campaign including PCs claiming and holding dominion over territory, the adventure itself does not include any large-scale battles or war-planning. You are the guest of the count, one of your allies and the strongest man in the region. Your sojourn has been pleasant, a nice change after weeks of battle. Suddenly the courtyard below your window is filled with the noise of galloping horses. More Guests? You yawn as you look out. But these people arriving look more like tax collectors than guests. You decide to give your attention to something more interesting, like dinner. Relax while you can, friend, because these new arrivals are about to lead you to a crimson sailor, a cozy Tower of Terror, and a river with an aching heart. Sabre River includes a complete campaign setting, new NPCs, dungeon and wilderness encounters, and a mysterious story. TSR: #9119, published 1984
