There are times when you miss so obvious a connection that its easy to bypass the forest for the trees in this case the rpg trees. This is the case with Empire of the Petal Throne rpg & Kevin Crawford's Worlds Without Number.
And this got me thinking about the pleasure planets, colony worlds, etc. creations of the Human Space Empire. We know that Kevin Crawford did a rules light play version of Empire of the Petal Throne back in 2015 available from Tankard's Tavern here called Swords of the Petal Throne. My question becomes just how far did the Human Empire get & how many of those worlds are still out there?!
We know that the Human Empire were using planar technologies & universes to power certain devices & artifacts aka the eyes and other magic items. This is very much in keeping with some of the Jack Kirby like technologies of Kevin Crawford's WWN rpg. And yes the Godbound uses some of the same technologies. But the scale of Godbound vs Crawford's WWN rpg are a bit off. So let's concentrate on Worlds Without Number for a moment. Let's say that shattering of the planes by the taking of Tekumel causes some of the background of Stars Without Number in the form of the Scream. This event shatters the planar gates & splits the various Earths in Worlds Without Number as well. This might also explain the stranding of the Starship Warden & the fluttering of the Nexus gates on Arduin.
