Hola!
Look at this interesting downloadable file.
In this site http://www.candlekeep.com/
Search for this: Also by Jared Rascher's, a fantastic article based on the recently announced events in 1385DR, entitled Anatomy of an Apocalypse.
And download this: Anatomy of an Apocalypse.
I mean, is it canon? Because if it is so, I'm so happy if Shar is going to die forever. 
Uh? More precisely?
it's how fan handled all the 1385 DR mess, I would be glad that this is canon but it's not
this thread explains it:

Now I see.
Do you know which is the canon FR explanation of this disaster?
from the Grand History of the Realms
and this

So what's so different about Mystra dying this time?
the difference is that Shar now somehow blocks the ascension of the new Mystra :roll:
But without the weave the shadow weave cannot exist.
The last is the shade of the 1st. Without the 1st the other one will die. And if the shadow weave dies, so will do Shar.
I'm really wondering how torilian wizards will use raw magic without the weave...
Maybe they will use the power of the Tree of Soul.
They did before the fall of Netheril. The Serpent Folk certainly had no problems with magic and that was long before the ascension of even Mystrl (Mystra's predecessor).
Now if only when they'd done their reboot they'd just had those two goddesses kill each other off and the backlash be things going back to their pre-Weave configuration with resultant devastation and de-stabilized civilizations I would be happy.
By now RPG designers should have learned not to make this mistake. There should never be a Divine Entity who controls magic. Gods who are renowned magicians and patrons of magic yes. But magic should always be a force to be used rather than a thing over which any entity has total control.

you can't apply logic when it comes to 4e and spellplague
Mystra is the Weave, meaning she is the interface for accessing raw magic. Magic of Faerun states that the shadow weave is an echo that interface, and is under control of Shar but it's not Shar (that's why Cyric wanted to steal it). When Mystra died before that interface was ''rebooted'' immediately cause Ao cared, and accessing raw magic without the weave would be dangerous, in 4e it's not :roll: . The Weave had existed throughout the entire history of Toril (including the Serpentfolk time).
The horrible abomination of adventure called Anauroch: Empire of Shade retconned that Shar doesn't need the Weave, but wants to destroy it so that her Shadow Weave is the only way of casting magic. In 4e shadow power source replaces the Shadow weave, She created Shadowfel, probably from the plane of shadow and the negative energy plane.
Sorry, but I disagree.
Shar beleives she is not influenced by the shadoweave. But she is.
Remember how the weave was created? Selune used a part of his essence to generate it.
If the Shadoweave is the precise opposite of the Weave, so did Shar, with the difference that the Shadoweave is not a separate deity, like Mystril was, but still a part of Shar body.
I don't know and care about their inconsistency
the Weave was created from essences of Shar and Selune, original Mystryl had a dark side, it's speculated that the shadow weave was created much later
I can ask around if you want
Ok 
no, it's a fan's take on the crap that is spellplague
current FR designers stick to divine soap operas
