The film has several explicit references to the AD&D game. A map during the opening credits contains the name "Yeenoghu", a demon lord from the game, and another demon lord from the game, "Jubilex", is mentioned by the characters several times. Also, several references contain the names of AD&D adventure modules (published scenarios). Berek mentions that Dorian helped him in the Ghost Tower of Inverness, a reference to module of the same name (C2). Nim asks Lux what happened to her brother at the "Barrier Peaks", a reference to the module "Expedition to the Barrier Peaks" (S3). Lux makes reference to the Shrine of the Kuo-Toa, a reference to the module of the same name (D2).
Magic runes seen in the film come from two sources. The first source is the set of zodiac symbols from astrology. The second source is The Chaosium's role-playing game "Runequest", which was a competitor of the original D&D and AD&D games in the '70s and '80s.
Lux's name itself is a game reference. Strategic Simulations Inc. produced a series of computer games based on AD&D, one of which is called Pool of Radiance In the game, you have to search out passwords for unlocking certain locations. Lux is one of a trio of passwords you need for an island keep filled with skeletons. They are Lux, Samosud, and Shestni.
