The renegade dwarf wizard Owlbeard has allied with evil forces from the Underworld and launched an attack on his former dwarven clan. While the dwarven clan battles Owlbeard’s legions in the open air and upper caves, the player characters are on a mission to sneak through the deeper reaches of the Underworld to locate the wizard’s secret lair and assassinate Owlbeard. As the player characters make their way through the Underworld, they must survive various perils, possibly make some allies, and race against time to eliminate Owlbeard before the wizard’s forces defeat the dwarves. Level 3 characters provided, or bring your own.
