The Multiverse — Hex Version (1986)

With the Immortals Set in 1986, the first official diagram of the cosmology of the planes made its debut. This makes my visualisation somewhat obsolete, but I will continue to update it for the sake of completeness.

There was a major change to the cosmology this year, which quickly becomes clear if you compare it to the previous versions: the planes of fire and earth have switched positions! This seemed like such a fundamental change that I wondered if it was a mistake, but Frank Mentzer himself confirmed that the Immortals Set configuration is the correct one.

The Immortals Set also added the idea of finite and infinite planes. This unfortunately makes my “1 hex equals infinity miles” scale wrong, and to reflect this I have included an infinity symbol beneath the names of each of the infinite planes.

Chronological Map (February 2022)

This map is part of the Mystara 1986 series of chronological maps. It is an updated map, incorporating all available sources and made internally consistent with other maps in its series. But it only uses sources published in or before 1986.

For more information, see Appendix C: Cartographic Chronology.
