A Complete Guide to the Cosmos - A Summary of Multiverses

by Giulio Caroletti

We have long discussed the Nature of the Normal Tetraspace and described the Prime Planes, the Multiverses and the Outer Planes and their peculiar features. Here is a Summary of some of the Multiverses; their description is presented in the next articles.

(Name of Multiverse)

Prime Plane: indicates RPG or literary campaign worlds appropriated as planets for the Prime Plane of this Multiverse.

Immortal Structure: details briefly the structure of the godlike hierarchy. "Free Godhood" is the standard AD&D type of godhood, with mortals able to become gods, gods slain and so on. "Spheres of Power" means that there is an Immortal Hierarchy of some sort, similar to that of the D&D Mystara campaign, or some other very hierarchical and rigid good vs evil or chaos vs law. "No Gods known" is a situation like Ravenloft or Dark Sun where there are no recognised gods or pantheons, because gods are too distant or simply not present. "Forbidden Ascension" means that there is no way to ascend to godhood in that Multiverse, as godlike beings forbid and prevents that situation from happening.

Outer Planes: gives a small description of the Outer Planes of this Multiverse.

Connected Primes: these Prime Planes may be reached through gates in the Ethereal from the mentioned Multiverse.

Level of Outer Being Influence: It is what it seems, just a description of how much the Outer Beings are able to influence the Multiverse through their vile scheming and telepathic abilities.
