Mountain of Mystery

[2] Dimension Six, based in Englewood, California, appeared in 1980 and published a number of products that year for fantasy role-playing including Furioso, The Nine Doctrines of Darkness, and Mountain of Mystery.

[3] The latter is a typewritten 24-page saddle-stapled softcover book designed by Ken Richart, with artwork by Carol Knight, Michael Carroll, and Vandy Vandervort.

In the September 1980 edition of The Space Gamer, Aaron Allston was not impressed, and thought the work of converting this generic adventure to a specific game system such as AD&D was not worth the effort: "All the conversion-ease claims might be overlooked if this were an imaginative or fun dungeon.

"[1] In the February 1981 edition of Dragon (Issue 46), Tony Watson mentioned the low production values: "As a general rule the artwork is acceptable, but varies greatly in quality and craftsmanship.

To make [this work] flexible enough for use with different systems, there have been a lot of minor details omitted that will have to be added before play begins."
