And you would be quite far off the mark in assuming the
MotP was the planes as envisioned by EGG. And you need not take it from me, as he has opined so many times, including the "Q&A" thread on this board. (Which isn't to slam the
MotP, its author, or its fans.) Indeed, Moore's Astral Plane article in
Dragon and DCS's
Queen of the Demonweb Pits present remarkably different views of the Planes than what was served up in
The Dragon early on by EGG, or in the
PHB, or by Kuntz and Ward in the
DDG. What's a DM to do? Pick which one(s) work best for him or her and go with it, of course. Which seems to be what you and I are doing.
