The Aethervane campaign exists within the larger Multiverse that contains all D&D campaign settings that are being played and have ever been played. The Multiverse is a shared fabric of lore that all D&D campaigns draw from and iterate upon without interacting directly with each other. For example, in the Aethervane universe, it is possible to travel to the City of Brass or to encounter Lolth, as players in countless other campaigns have done, but each campaign has its own iteration of these aspects. If, in the course of the Aethervane campaign, Lolth is destroyed, that does not mean the same happens in all other campaigns. And although the basic gist of the City of Brass may be the same in every campaign, its exact features and history as portrayed in the "Aetherverse" are unique to Aethervane.
When in doubt, the various planes, settings, and deities that are part of standard D&D lore exist and behave as described in the officially published 5e sourcebooks. That being said, any number of new worlds and gods can and will be added onto the default lore over the course of the campaign.
Traveling between worlds and planes is what ties the scattered Aethervane settings together. Aside from spells like plane shift and gate, which can be cast only by high-level mages, there are two main ways to travel the Aetherverse:
In each campaign within the D&D Multiverse, there are typically a number of extradimensional planes of existence, but the exact number of planes and their cosmological arrangement varies from campaign to campaign. The Aethervane campaign uses what is known as the “Great Wheel” arrangement (the default model for D&D 5e, as outlined on pages 300-303 of the Player’s Handbook and detailed on pages 44-68 of the Dungeon Master’s Guide).
