From the Kickstarter:
The heroes are sent into the Devil Lich’s crypt to destroy her before she can return to power, as foreseen in a prophecy. However, the unknowing heroes have actually been tricked into entering her crypt to free her from her prison. If they are truly heroes, they will uncover the deception and defeat the evil Devil Lich before she can unleash her dark designs on the surface world.
Created in homage to Gygax's classic with the goal of providing an even greater challenge, Crypt of the Devil Lich became an instant legend when it was first run as a tournament dungeon crawl. After all, this is the adventure with a mummy dragon, the hall of prophets, and a castle suspended by chains above a lava sea - not to mention a legendary villain! Now, more than 15 years after its original Gen Con debut, we are updating it for the 5th edition and DCC rules sets.
Perhaps the most cherished dungeon crawl ever published by Goodman Games, Crypt of the Devil Lich has been completely updated and converted to new rules sets. It’s ready for your table: are your players ready for the devil lich?
