Well, both Forrester and Kalanyr are trying to redirect the missiles.
I have a ruling to make on that.
The missiles are redirected, but Forrester and Kalanyr were not working in tandem - there was no time for them to work in tandem.
The missiles redirect, in all directions.
There were only 500 missiles, fortunately.
Half of them fly up into space.
One quarter fly off and hit random parts of Oerth.
The remaining one quarter hit the Flanaess in random locations.
Some even turn and nose-dive directly into the ground.
The entire world of Oerth lights up like a sun again, as the huge explosions go off (they are 200 megatons, NOT 200 gigatons or 200 terratons ... Mr Draco, I thought suicide was Rhialto's tactic!)
There is obviously wide spread mass destruction and carnage.
However, by some stroke of luck, none hit close to cities.
Close enough, that is, to do more than moderate damage.
It is the countryside that gets it, and the unfortunate population out there, but there there are fewer people.
The major woodlands of the Flanaess all burst into flames, either from direct hits, or from the radiant heat.
Fires break out across every city in the Flanaess from the flash effects.
Millions of people are permanently blinded, and millions are burned, some horribly.
In the battle raging in the midst of the Flanaess, everyone - even the Demons, stops fighting and gapes as the whole world lights up around them.
Ironically, the light helps the good guys.
The Shade cannot abide or tolerate light of that magnitude ... they are especially vulnerable to it.
By the thousands, the Shade scream in their death throes, bursting into flame, and fading away.
Those that escaped that fate, are blinded and stunned, unable to fight.
Unfortunately, a greater part of the attacking force was also blinded.
The assault against Acererak by the forces of the Dark Union comes to a sudden halt as the world lights up around them, and half the army is blinded, having the misfortune to be looking towards the blasts.
Aren't you glad antimatter bombs don't cause radiation?
