Level 16: Crystal Labyrinth - Waterdeep: Dungeon of the Mad Mage

Level 16: Crystal Labyrinth. Githyanki recently turned the Crystal Labyrinth into an outpost of their interplanar empire. It houses a gate to Stardock, a hollowed-out asteroid in orbit around the planet Toril (one of many that form the asteroid cluster known as the Tears of Selûne). Together, the Crystal Labyrinth and Stardock are designed for four 14th-level characters. Those who defeat the monsters on this level should gain enough XP to advance halfway to 15th level. Before running this level of Undermountain, you should review the "Gith" entry in the Monster Manual, because it contains information that will help you roleplay githyanki effectively. Additional information about githyanki society can be found in Mordenkainen's Tome of Foes, although that resource is not required to run the Crystal Labyrinth. What Dwells Here? Githyanki tracking a splinter colony of mind flayers to Undermountain seized this level and turned what was once a crystalline maze into a fortress. From here, they launch attacks against the mind flayers on level 17. The githyanki also transformed Stardock into a crèche: a fortress dedicated to raising and training young warriors. Because creatures do not age on the Astral Plane, the githyanki must bring their offspring to the Material Plane to mature. Unfamiliar with the asteroid's actual name, the githyanki refer to Stardock as Crèche K'liir. The Original Crystal Labyrinth Undermountain: Stardock, written by Steven E. Schend and published in 1997, was the third of three modules in the short-lived "Dungeon Crawl" series of adventures designed for the second edition D&D game. Waterdeep: Dungeon of the Mad Mage presents alternative versions of the Crystal Labyrinth and Stardock scaled for fifth edition and this product. If you want to expand this level of Undermountain, the original adventure would be a fine source of inspiration.
