So before we move on, I would like to give my guesses on what this actually means

So, Warring Royalty is the chess pieces. I mean, it was implied since Nanaquin talked about “good vs evil”

Every chess board is fought with Kings, something that my poor Imp Traveler has bad memories of

The Timeless Expanse was what John set off. Because he entered this world of where ever the fuck, he expanded the chess board.

So now there will be a greater war. And based on the destruction going on on Earth, as well as the references to different planets, this war isn’t contained to this plane.

Agents, Exiles, Consorts, and Kernelsprites. There are main types of players here in this world. Agents to probably work for the kingdom, Exiles like Mr. Desert Dude who reject it, Consorts who help rule it, and the ever wonderful Kernelsprites who will act as guides for our main players.

Underlings and Denizens is a bit self-explanitory.

And finally, the names of our 4 Players. Heir of Breath, Seer of Light, Knight of Time, and Witch of Space. They have to be John, Rose, Dave, and Garden. There is no way around it.

Garden is the Seer, she has been doing future-vision stuff since she was introduced. Rose is the Witch. She does have some occult stuff going on. The Knight and Heir is a little more tricky. I want to say that Dave is the Knight since he has swords, leaving John as the Heir. But I have no Idea what “Heir of Breath” even fucking means, even as a vague job title.
