I've been doing my own conversion of Planescape (using a LOT of what Planewalker is doing and just tweaking stuff for 3.5), but one thing that's bugging the bejeezus out of me is the Plane of Shadow. I'm totally up in the air as to whether to keep it as a Plane itself or toss it back to Demiplane status.
Quick note: I'm sure all of this has been discussed before, but a quick search yielded nothing, so hopefully this isn't a repeat (if it is, somebody point me the right way and I'm there).
I've got most of the PS books, as well as most of the 3.5 stuff, but I just can't seem to grasp what the big consequences are for the Plane of Shadow. I like the Ethereal being the link between Prime worlds as opposed to the Shadow, but is there any other things it'll effect?
Your comments, questions and suggestions would be much appreciated! BTW, this is my first post, so howdy to all you stylin' planewalker (and Planewalker.com) folks! PS is the best campaign setting I've ever discovered, so keep up the good work too. [end schmoozing]
Howdi, neuronphaser. Welcome aboard. Don't get too comfortable; we'll be grilling you in no time!
Although this is not canon, I've always thought of Shadow as being the border region between the Positive and Negative Energy Planes, with Light and Darkness blending to create Shadow. Intersecting Shadow with the Prime Material Plane creates the Inverted World, where your evil doppelganger rules the world. As such I consider Shadow to be more of a matter/elemental plane than a transitive plane.
The 3E interpretation elevates shadow to being a separate transitive plane almost like the Shadow found the Amber novels of Roger Zelazny. It is a place where different realities meld together, and you can travel through shadow to any other place in the imagination. Even back to 2nd Edition D&D!
