From publisher blurb: The Demon Tower of Valdig Fel is the first adventure specifically set in the Isle of Eldisor Hexcrawl Campaign Setting. Designed for use with Labyrinth Lord, it is easily adapted to any OSR-Style Role-Playing Game. The Demon Tower of Valdig Fel is an ancient, much-storied flying citadel in the shape of a demon’s head. Since the death of its creator during the Wars of Succession following the Fall of Eldisor, it has passed through the hands of countless villains, who have used the flying tower to raid, pillage, and enslave the peoples of the Ivory Plains and beyond. Terrible tales of wizards, demons, and dragons follow in its wake. And now it has drifted into a tree-lined ridge near Wulf’s Ferry… right in your own backyard! What are the inhabitants up to? Are they here to raid or to trade? What of the rumors of centuries of treasure hidden within? Are you brave or foolish enough to find out? The Demon Tower of Valdig Fel is designed for use with Labyrinth Lord and other OSR-Style Role-Playing Games. Designed for use for a party of 4 to 6 adventurers of 5th to 7th level, its dangers can easily be increased or decreased for more powerful or less experienced parties.
