Allenthrellus, looking haggard and exhausted, communicates to Iuz:
In a few hours, Iuz, the Shade attack will go off.
It cannot be stopped by any force we possess, or by any force we are aware of, including the Diadem of Dreams.
Nor can the Diadem of Dreams blunt it's effects, or stop it's advance.
There will be an explosion - an explosion equivalent to a Supernova.
This explosion will be an explosion of negative energy.
A blast wave of Shade, travelling at thousands of times the speed of light, will pass outward from the main blast.
In a fraction of a second, it will reach Toril's sun and extinguish it.
In about one second, it will reach Toril and literally eviscerate it into Nothing.
Allenthrellus leans heavily against a supporting wall, and continues:
The Weave will be destroyed when this happens.
The Shadow Weave will be pulled into the explosion, and will magnify it.
Melkor's prison will be destroyed, and his essence pulled into the explosion, which will magnify it.
Within a minute, the blast wave will reach, and shatter, the Crystal Sphere that holds Realmspace, and pass into the Phlogiston.
The Phlogiston will freeze into a solid at near Absolute Zero, a labyrinth of darkness the likes of which the Spheres have never seen, barring only the Prison of the the Lady of Pain.
In less than one day, the leading edge of the blast wave will hit Greyspace.
Greyspace will be completely destroyed ... only a burnt out ember will remain, and that of Oerth's sun.
In one and one half days, the blast wave will reach Krynnspace.
In two days, the blast wave will reach Mystara.
In four days, the blast wave will reach Athas.
You cannot stop it with your 11th level magic.
WE cannot stop it with our 12th level magic.
Those whom you call the Deities cannot stop it, for their power is bound up in it.
Before the blast wave exhausts itself in the Phlogiston, it will have destroyed more than a dozen Crystal Spheres.
The blast wave will travel through the Ethereal Plane, starting at the point of the blast.
The Ethereal Plane will shatter and be destroyed by the blast - the Border Ethereal will collapse, and withdraw from the leading edge of the blast.
Anything in the Ethereal Plane that is in the way of the blast, will be destroyed.
The blast wave will travel through the Astral Plane.
It will crash against the First Layer of the Outer Planes.
It will finally be halted there by the combined might of the Powers of the Outer Planes.
(Now Allenthrellus really staggers, and falters, then communicates slowly and painfully)
The blast wave is keyed to you.
Remember how the Elder Ones came directly to Greyspace?
Remember how they came directly here, when all of Reality lay between you and them?
The blast is keyed to you in this way.
It doesn't matter where you go, or how far from here you flee.
You could travel to another dimension, another reality, and it would follow you.
Perhaps, in the Outer Planes, you might survive, and then again, you might not.
The Powers (Allenthrellus falters further) are vey displeased with you.
We know ... we have felt it.
You will receive no protection from them.
They will not intervene to save you.
The God Emperor, Kalanyr, and Kas did not have the power needed to save their people.
The blast wave will pursue them, keyed to them specifically - it will pass right into the 50th level of Mechanus if necessary.
(Allenthrellus staggers, and says mournfully)
Melkor planned his attack very well.
The Red Poison from hundreds of worlds is the initial fuel.
The hate of the Shade for all that lives is the necessary explosive.
And ... and the suicide of billions of Shade will cause a chain reaction.
(Allenthrellus staggers, and says weakly)
There is a way out ... a way out for you people ... a way to survive ... we tried to help you ... but ... against power of this magnitude ... it takes more than mere ... power to ... stand against it.
You must ... become greater than ... you dared to hope to be. You must ... somehow ... you must somehow ... you must somehow put aside the hate and fear that has so defined ... your existence ... only then ... is their hope.
