Speaking of lore, though, something that
@TalonofAnathrax mentioned last night kicked something in my brain. Lemme find it, one sec.
Oh, and in the past DP has heavily hinted that Tiamat is strongly linked to it. We know that she has power there and mighty servants upon that plane, and that the Sundering (and event focused on our Plane, which Tiamat seemed to rule at the time) began where the Shadow Plane touches ours (in Asshai probably).
So we have a Sundering event that is implied to have begun where the Plane of Shadow touches ours. We have
extremely heavy implications that Taimat is strongly linked to and holds a vast amount of power there. We also know that Valyria
destroyed Chromatic dragonkind as a race on the Plane of Balance through the ritual that turned them into Valyrian dragons. And it's nothing less than destroyed, don't fudgeaboutit. And then...well. We have
this.
"You strain the weaving. It will come sooner now,"
The Sundering obliterated Valyria, the bastion of a power built not just on the summoning of devils and blood sacrifice, but also the utter annihilation of Chromatic dragonkind as a species on our Material plane. I can't imagine that Tiamat would have taken such complete eradication of her primary source of worshippers well. So she turns to the Plane of Shadow, a Plane that we know breeds paranoia and distrust. Shadow creeps into the spaces between the light, no matter the source, and finds cracks through which it can spread. There's a story already on record about how the Plane of Shadow can bring down an empire; Neverwinter Night's 2. Now, to be fair, what happened there with the Guardian becoming the King of Shadows was exceptional. Karsus' Folly had to occur, breaking the existence of the Weave for a bare minute, but that was enough. And Ilfearn fell as a result.
To put this another way, the Plane of Shadow is one well known for creating horrors that reach through breaks in the light. The failing of magic was only one part of the Sundering, itself an inter-planar cataclysm that shattered the links between realities so terribly that they've still not fully recovered. It's a fragile system the the Material and all else exists in, and Tiamat had every reason to seek vengeance on a world that had snuffed out her children. She's nothing if not vicious when it comes to her reprisals. And note what Syrax said in that dream.
It.
It implies a thing, but a thing doesn't have to be inanimate. Valyria fell in fire and a rain of blood, but if the Sundering didn't
start there, how did it travel? How was it possible to keep at bay, if only for a while? That strikes me as more a spell, or a creature, one that even Gods couldn't fight. Any plane can make those, but the Plane of Shadow is uniquely suited to it. In the FR continuity, Shar made the Shadow Weave as her own way of stopping the Goddess of Magic cutting her off from it - a power Mystra did possess, she just couldn't stop true worshippers gaining divine power. The Shadow Weave gave Shar access to magic that Mystra couldn't control, did the same to her worshippers, and also was part of what allowed Mystra to eventually be
murdered, which loosed the Spellplague on the multiverse. Let's repeat that: on the
multiverse.
To wit, a theory. The Sundering wasn't (just) an Event. It was a Thing. A creation of shadow and magic and divine hatred and spite and maybe even death as well - for all we know there once
was a deity of magic, and the Valyrian gods were only trying desperately to hold back the Sundering - and in doing so actually made the end results
worse. But imagine. Taimat is called the Mother of Monsters. She earns that title. But she's still a mother, and even if her children are pawns, Valyria
murdered not just them, but their legacy as a species.
Valyria was the heart of magic, and that is a good reason for why the Sundering broke it so. But it was also the Empire that humbled a truly spiteful deity in the worst way, and then gave her centuries to orchestrate vengeance.
Think about it. I might be wrong, but if I'm
right...
