I have read up about Planes, about the Great Beyond, basically the whole of http://www.d20pfsrd.com/gamemastering/environment/the-planes and http://pathfinderwiki.com/wiki/Inner_Sphere
I was wondering how to handle if a Material Plane gets destroyed or it disappears. A friend of mine and I both have different perspective on this. I think that nothing happens except for the link to the Material Plane disappears. My friend thinks that if the Material Plane get destroyed, the whole Inner Sphere gets destroyed.
I do know that we can get creative when it comes to our own interpretation, but I was wondering about Pathfinder lore interpretation. How is it handled, according to lore?
