From publisher blurb:
Fire and Frostbite
The dragon-blasted stellarium inches toward destruction as the glacier grinds itself to its doom between two mountains. Treasure and eldritch lore will certainly be found within, but you are not the only ones who have come to claim its secrets.
Stellarium of the Vinteralf is one of the Ennie award-winning Trilemma Adventures by Michael Prescott. This version contains the original dungeon, expanded to include ELEMENTAL stats and a flavorful cast of player characters with their own agendas and motivations.
Drop Stellarium of the Vinteralf into your campaign or play it as a one-shot. Hand out the provided characters, place them at the entrance of the site and you can enjoy a session of gaming right away, with as little preparation as a board game.
