Editing The Valley of Darkness:The Main Plot (section)

=== The Truth Behind the Darkening: ===

To cut to the chase, the truth is that the valley is mostly in the Plane of Shadow (PoS).  The Shadow Lord Hexablacorps (a silly name I gave him, that has no meaning) put certain events into action over the past millennium that ultimately resulted in a very significant portion of the valley being shunted so that it is mostly in the PoS.

Much to Hexablacorpse's shagrin, the great ritual event only brought the valley into his plane partially.  His original intent was to bring the majority of the valley into his plane.  By saying the valley is partially there, and that he wanted the majority it, is to make a very deep statement of magical theory.  The movement of the valley to the PoS would not be a physical movement, as all great minds of magical theory understand, the valley, and all other geographical, as well as many very old or very magically powerful buildings and constructs, already have physical representations in the PoS, it is the spiritual and magical existence that important to Hexablacorpse.  It was his desire to make a passage between the PoS and the valley much easier for he and his kind.  

If his original plan had succeeded as Hexablacorpse had intended, then not only would he, and the denizens of his section of the PoS have direct access to the valley, there would also be easier movement from the PoS to the Prime Material Plane of Toril.  However, as it worked out, only the weakest of his subjects have any access to both the sliver of the Prime Material Plane of Toril, in the form of the valley, but they have an even more limited access to Toril as a whole.  Hexablacorpse has found this to be infuriating.
