Inferno is the first original 5th Edition Campaign Setting adapting Dante Alighieri's "The Divine Comedy" into a tabletop roleplaying game.
Dante's Guide to Hell is the game's "Player Handbook," and it focuses on the Lost Ones, living beings forced to enter Hell, including 12 brand-new Archetypes with a 1-20 level progression, setting specific rules, and a deep description of the INFERNO itself.
