[The Tetherer frowns at the mention of other gods. They're... aware they must exist, in some fashion, but everything they've been taught since an early age was that they were one of the only three. And the three don't Create anything. They simply monitor and curate the worlds.

The cycle of Separation, Tethering, and Destruction. That was all there was.]

This is the first I've heard of it. Your world must be... outside of my purview.

[Since that's fairly large scale, and if someone was consuming realities, they'd be aware of it almost instantly.

Could there be worlds other than those that were Separated from the original world, where everything existed?]

Or perhaps there are worlds that were never Tethered. They are countless, after all. Well, it sounds like an incredible story, either way. You'll have to tell me the whole thing sometime.
