Halaster's Lost Apprentice

A lost passageway on the upper level of the most infamous dungeon in Faerûn has recently been uncovered. When a patron hires a band of adventurers to brave the dangers of Undermountain, a search is on to uncover secrets of an apprentice of the dungeon’s lost creator – Halaster.



“Undermountain: Halaster’s Lost Apprentice” is of course set in Undermountain, the infamous Waterdeep dungeon that was originally described in Ruins of Undermountain (1991). This adventure just barely touches upon Undermountain’s vast delves, but it nonetheless shows how the setting has changed with the Forgotten Realms Campaign Setting (2008) update. The first level of Undermountain now contains “Downshadow,” a community peopled by “down-on-their-luck adventurers, criminals, and folk scarred by magic.”

Halaster’s apprentices, known as The Seven, have long been important to the mythology of Undermountain. City of Splendors: Waterdeep (2005) and The Grand History of the Realms (2007) together name all seven: Arcturia, Jhesiyra Kestellharp, Nester, Marambra Nyghtsteel, Muriel the Misshapen, Rantantar, and Trobriand the Metal Mage. Apparently there was also one more “Lost” apprentice, who appears in this adventure. Sadly, there’s not much detail on her, as there just isn’t space in the terse Encounters format.
