Suddenly summoned into the great sky castle of Stormridge Sanctum by the magical incantations of Clovis Tempestas IV, the characters are tasked by the foppish storm giant finding the source of the infestation plaguing his wine cellar and purge it before he loses any more of his precious libations. After being set down in the cellar, they must contend with environmental hazards in a domain built for a creature ten times their size.
