From the author's Foreword: "Inferno is based primarily upon the poem "Inferno" by Dante and is also fitted as a scenario into my campaign, Nidevellir. My purpose in writing it is twofold -- first, to answer the perennial question of Judge's when the party finds a cursed scroll: "GO DIRECTLY TO HELL!!" now what do I do? And secondly, to provide a power base to the evil immortals in the campaign. There may arise occasions in which an irate Cleric will geas some poor fighter into returning something that is on the Devil's plane and this allows the character somewhere to go for the adventure."
