Rappan Athuk, the legendary mega-dungeon by Frog God Games and Necromancer Games is nothing more and nothing less than a good, old–fashioned, First Edition dungeon crawl updated for D&D 5e.  Very difficult, Rappan Athuk will truly strike fear into the hearts of the most stalwart adventurers. It offers legions of inventive traps, tricks, strange features, and monsters -- many of them never before seen. It affords numerous opportunities for roleplaying, but anyone willing to brave these subterranean halls better arrive ready to rumble, or their lives will be short indeed.
