Oh, hey, I do agree with you. I mentioned earlier upthread that I'm basically shouting at the wind. TSR rammed Planescape into the core identity of D&D and there's no going back now. I just lament the fact that we have to follow this canon because I find it so incredibly stifling to creativity. It's just not my bag and I was hoping that 5e, like 3e and 4e, would strip most of it out again.
C'est la vie.
Really, all you need to do is to tell your players something like "In this game, there is no Great Wheel. I've created my own cosmology. You'll learn about it through play, so make no assumptions about any worlds beyond your own, and be sure to consult sages or do research before interacting with any extra-planar [or whatever you want to call them] creatures. Consider this a warning." Be sure to give them the evil DM look, complete with a smile that will give them nightmares. They won't forget. If they're proactive, make a one page printout for what their characters think the afterlife is like, or whatever, to give them a basis to go off of.
