Monte Cook, the mind that created some of gaming’s most storied megadungeons—including Return to the Temple of Elemental Evil, A Paladin in Hell, Ptolus, Dungeon-a-Day, and The Darkest House—now brings you Jewel in the Sky. Backed by a team famous for elegant and imaginative design, awe-inspiring artwork, amazing production values, and innovative, super-usable products, Monte brings his immense experience and imagination to a huge dungeon filled with excitement and surprises!
Vocurro. The Jewel in the Sky. An eight-mile-long island floating 1000 feet above the distant mountains. It’s famed for the magnificent Crystal Cathedral, and riddled with inveigh mines—source of the precious, gravity-defying mineral that powers airships and so many mystic applications. It’s long been coveted by the powerful and the magical, who over the centuries have built untold catacombs, fortifications, and dungeons on and in this famed floating isle.
Vocurro is also home, unknown to all, to the hidden base of the visitors. These strangers from the stars have for years visited Vocurro in secret, posing as natives when it serves their purposes. And they’re equally interested in the strange properties offered only by the mysterious mineral inveigh.
Now the visitors have lost contact with their secret base. And over the centuries magic has corrupted technology, and technology has corrupted magic. By anyone’s standards—natives and offworlders alike—Vocurro has become a very strange, and very dangerous, destination.
What happens when magic and technology don’t just merge—they collide and corrupt each other? And along the way attract demons from another plane; a shadowy cult with a mysterious agenda; a cabal of powerful figures making Vocurro the nexus of their schemes and plans; and more?
Delve into Vocurro’s daunting maze in this massive dungeon adventure. Explore its dank and ancient passages, discovering mysteries, riches, dangers—and loads of surprises. Jewel in the Sky fits easily into your fantasy world—or in any space opera sci-fi setting. Because you can…
Dungeon fantasy or space-opera sci-fi? Jewel in the Sky is two megadungeons in one, because you can play it either way! No matter how you play it, you’ll discover interesting twists that take your players’ imaginations to places they’ve never been.
- Through what magic might a clever sorcerer turn a simple communication device into a weapon that threatens the entire world?
- How can unquiet ghosts and fusion radiation possibly exist in the same world—and what happens when they mingle?
- How does an AI cope when it finds itself abandoned on a planet where magic and spellcraft dominate?
- How does a lone android survive when the magical energies of a strange new world begin to alter it both physically and mentally?
- And how does a sleeping god react when these events begin to wake her?
Play Jewel in the Sky as a classic fantasy dungeon filled with strange and unusual discoveries. Or drop it into a space opera sci-fi game, and play as the visitors reclaiming their base on a world unlike any ever encountered. It’s specifically designed to play either way—and to deliver twists and surprises that will make this dungeon crawl a weird, exciting, and memorable adventure!
