Based on the original work by the grandmaster himself, Gary Gygax, Necropolis is an epic desert adventure series for 5e D&D and Swords & Wizardry. Previously published by Necromancer Games as a d20 system adventure, it has been entirely updated and revised by Mark Greenberg, co-author of The World of the Lost Lands by Frog God Games.

This grand adventure is set in the Triple Kingdom of Khemit, on the continent of Libynos in the Lost Lands, the world of Frog God Games and Necromancer Games. Necropolis is designed for a party of 6–8 seasoned characters starting between 7th and 9th level and will challenge even the most experienced players.
