But were the borders on the Crystal Sphere "hard"? Put in other words, if you kept distancing yourself from Oerth and further into Greyspace, would you eventually bump into a physical, invisible wall? Or would you keep on going unless you knew how to exit that Crystal Sphere? And now, the reason why this might be relevant to this thread, though it's merely speculation: if the latter were to happen, than wouldn't the Phlogiston be better thought of as some sort of "hyperspace", a "layer" to the Prime Material (however odd that would be!), or even a Transitive Plane that shortens travel time (Plane of Shadow, anyone?!?), instead of merely a part of the Prime Material?

1.Each Crystal sphere is hard and solid.
2.Crystal Spheres are not invisible, so you'd have to want to crash into a solid curved wall.
3.You can think of the Phlogiston as ''HyperSpace'', it fits well enough.
4.Technically, Spelljammer wise, each Crystal Sphere is it's own ''Prime Plane'' as each Sphere has different laws of physics, magic and such.
