I posted this on the Wizard forums about the Weave and the Spellplague:
The Weave touches all living beings giving them access to magic if they learn how to access it. (In fact it was retconned from actually being tied to the lifeforce of everything in Toril). Without Mystra's constant attention, the Weave frayed and collapsed.
Imagine a net under constant tension. Parts of the net are tangled and parts of it are missing, though they are a small part of the total construct. Without the constant application of counterforces in certain parts of the net, it starts to unravel.
Near the dead spots the starting wave is stronger with ropes fraying wildly but as distance from those spots is gained the unravelling calms down. The wave of this unravelling is uniform as per the shape of the dead spot.
Near wild magic spots the net will unravel wildly. It will create swirls and eddies, untangle in different speeds because of cross effects and possibly even allow for small islands of calm within the affected zone.
In areas where the net was strongly anchored it will stay stable until all forces around it are uniform, then the net will simply collapse uniformly.
All these effects would of course work against each other. Still the majority of the net will unravel in good order without much fuss.
It stands to reason then that all the places and creatures touched by the weave will be affected when those strands that tie them to it are cut. The more violently ropes that tie them fray, the greater and wilder the affected changed will be.
