The Multiverse (1984)

The Companion Set formalised the concept of the multiverse and planes in the D&D game world. This isn’t so much a map as a conceptual diagram, putting the words of the Companion Set into visual form. There was no such diagram in the original book; this one is based entirely on the text itself.

It’s useful to visualise the setup in 1984, two years prior to the Immortals Set’s diagram, complete with its own revisions and additions.

Chronological Map (August 2021)

This map is part of the Mystara 1984 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 1984.

For more information, see Appendix C: Cartographic Chronology.
