Positive​/Negative no longer Inner Planes in 5e. Is there a story behind that or just liked it better that way?Do they still touch the Inner Planes in such a way as to form quasi-elemental planes (e.g. positive + air = lightning)?

No, that was the main change. Still realms, just weirder/more abstract than elemental ones

Thanks for responding! Can you clarify what you mean by “still realms”?They're planes, places you can visit (thought positive/negative are pretty difficult to survive in)
