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.

Revisions

For detailed notes, see the posts for each individual source map at the links above. With the Immortals Set’s revelation about Immortals having Home Planes, I have added lists of Immortals to the Textual Additions to each previous source including them. All such sources have been included in the Sources list above.

• Immortals — This list collects all the Immortals (or in older sources gods) referred to in previous products. For those sources with a map in which to list Textual Additions, I have added them there, too. Since Spheres of Power did not exist at the time these were written, an appropriate Sphere has been assigned based on alignment and/or elemental association. At times I have invoked the hindsight rule to reference Marco Dalmonte’s Codex Immortalis, but if the evidence at this time suggests otherwise, I have gone with the most likely Sphere rather than that in the Codex (for example, placing Cretia in Entropy rather than Thought).
  • Sphere of Matter: Forsetta, one of the “major gods of Vestland”, a “Lawful Order” supporting “belief in authority” and “good deeds” (X3 page 3b), N’Grath (IM1 page 20).
  • Sphere of Energy: Pflarr (B10 page 4 etc).
  • Sphere of Time: The Spuming Nooga, a “neutral order” believing “that a person must strive against the circumstances of his life to make the best of a short existence” (X3 page 3b).
  • Sphere of Thought: Oloron, Lord of the Skies, a “deity” (X1 1981 page 22b and 1983 page 23c).
  • Sphere of Entropy: Cretia, the “god of the Ethengarians”, a “chaotic god” which the text describes as “grotesque” and “hideous” (X3 pages 4ab, 18a, 24b); Drekk (IM1 page 3a, 21); Idris, an “ancient and evil being” and an “evil goddess” with temples and clerics in Denagoth espousing “Bribery, torture, blackmail, and self-gratification”, who resembles a “beautiful woman” and uses the black dragon as her symbol (X11 pages 10a, 11c, 16c, 48b, 58c); Kiranjo the Minotaur, a “bull-headed deity” with “foul priests” (MSOLO2 page 4a); Stodos, Master of the Icy Wastes, an “evil god” (MSOLO pages 13 & 23); Tapu, “pig god” of the kara-kara (X8 page 2b).
• Outer Planes — The Immortals Set made it clear that each Immortal had their own Home Plane among the Outer Planes. Although at this stage there were no names for these planes, nor indeed any kind of detail at all, I have decided to mark these planes on the diagram. There was no suggestion that these Home Planes were sorted into areas based on Sphere, and the diagram should not be taken to imply any plane’s physical location on the Astral Plane. In the absence of any kind of information about locations, I have simply marked them in a way that makes them easy to find.
