Mystery of the Snow Pearls is a solo scenario for one character, although it can be adapted to group play. The player character must solve the riddles of an evil mage to regain the magic pearl which protects the character's village.
The player is a Companion level elf, responsible for safeguard one of the four, magical pearls that protect the land of Tarylon. Milgo, an evil wizard with a sense of humour, challenges the elf to find and return the lost item. Without it, the entire region is threatened.
This adventure uses a "Magic Viewer" - a piece of colored film - to reveal the hidden results of the player's choices. This includes encounters, puzzles, and traps.
Mystery of the Snow Pearls was written by Anne Gray McCready, with a cover by Larry Elmore, and was published by TSR in 1985 as a 32-page booklet with an outer folder, and also includes a large map and colored film.
