Considering the attempted Coup against Melkor, I was considering ruling that the Shade were halting their Coup de Grace against Anabstercorian's Penumbral Hub.
Then I looked at how many Powers were Attacking the Shade.
The Seers of the Shade could clearly see an attack was about to commence against them, and that this attack would be massive.
Perhaps if they had not detected this incoming attack - perhaps if there had been no incoming attack - the Shade would have decided not to go ahead with their attack.
Perhaps reason would have prevailed (that is, I would have Ruled the Shade did not attack.)
However ...
The Seers DID see a massive incoming attack.
Reason was cast aside.
Seeing their imminent destruction (the odds said they would suffer 100 percent destruction ... they simply got lucky) they struck.
The result, is rather sad:
In Greyspace, lit by the purple sun, perhaps there was nothing more beautiful or majestic as the Penumbral Hub.
A slender, graceful ring, only partially completed, fully 70 million miles in diameter, encircling that sun.
Built of Sunstare, the mysterious illithid substance, it was miles wide and miles deep.
Eloquent towers and shapes adorned it's length, great windows looked out into Wildspace.
Here was the beginning of a whole new civilization, an evolution of both illithid and non-illithid alike, a new beginning.
The Shadow closes around the Penumbral Hub.
In the Shadow, the Penumbral Hub withers.
The Sunstare, gleaming in the sunlight, rusts, cracks, becomes brittle.
The atmospheric pressure on the inside becomes too great for the weakened metal.
Piece by piece, area by area, giant explosions begin obliterating the Penumbral Hub.
Those caught inside are caught in the 11th level Coup de Grace.
They wither as their bodily fluids evaporate, turning into dried up husks, then finally crumbling into ash.
A terrible astral howl, the voice of a million souls in agony, rocks Greyspace, as those souls wither into ash also, consumed by the power of Shade.
The explosions continue, the surface of vast parts of the Penumbral Hub turn black.
Eloquent windows shatter, towers break off, dropping towards the sun, great cracks appear in the main superstructure.
There is a great wrenching, the sound of tortured metal breaking and shattering, and the Penumbral Hub breaks in half completely at one spot, thousands of pieces of it richoted off into space, hundreds of people screaming as they are flung helplessly into the ether.
Finally, though, the Knights of Neraka (who are still without their leader, Mina) bring their 11th level magic to bear.
Powerful light springs up, clashing with the Shade, producing spectacular whirls and eddies across Wildspace.
Great shields go up, stopping the loss of air, saving the lives of millions of beings.
11th level magic fortifies the Sunstare, driving back the withering effects of the Shade, enabling those parts of the Penumbral Hub yet uncorrupted to withstand the assault.
When it is over, the Penumbral Hub is severely damaged, and millions are dead.
Effectively, the Penumbral Hub is half destroyed.
However, half of it is not destroyed, and still reflects the purple sunlight back in Sunstare glory.
In the half that survived, towers still stand, great windows yet look out into Wildspace, great minds survive, and the lore of the illithid is yet preserved.
