Help, Planescape people! Shemeska and any others!
All right, so to preface- in 1e and 2e, the quasi-elemental planes are at the points where the Positive and Negative Energy Planes meet up with the elemental planes. So where Positive meets Earth, you have Mineral; where Negative meets Air, you have Vacuum; and so on.
Now, in 3e's Manual of the Planes, one of the options is to treat the Plane of Time as the Temporal Energy Plane. So it seems logical that, where Time meets the Elemental Planes, there would be temporal quasi-elemental planes. So my question is, what the heck are these planes?
