Aurora almost brought Winter and Summer to the brink of war somethign that didn't happen in the last 1k years (Bob is 1k year old and he doesn't aware of it) we can assume base on info in Summer Knight that it might have happened when last ice age start or end, couple of millions of years.
Not to mention Aurora first tried to give Winter the power of Summer Knight and then Summer Lady attempting to ruin the balance totally (something that didn't happen before) and throw the world into for ever Ice age, extinguishing all life probably on Earth , might even end the Summer court and ruin the entire powers balance in DV.
One of the things that keep Titania or Mab in check is each other, no Mab or no Titania mean they will roam freely causing......
A coming of never ending Ice age seems to me pretty heavy
then some plague heavy as it is
Remember plague can roam as long it is has prey when it eaten all its prey it die , so if it is hitting hard it will vanish even faster after everybody died
and there will be always survivors at least not human.
read the theories of why Dinosaurs no longer roam the earth, it wasn't the meteor that killed them all or the blast from the impact it was the fact 1k years of total winter is what brought their end (assuming it was a meteor and not a result of Winter winning the war
)
If DM prophecy didn't exists what would have happen ?
The knights would still gather in Chicago they follow evil regardless if there is prophecy or not.
Dresden would have help them fully from the start, instead been kept out cause of half prophecy and then hunt the full one to find he is totally needed.
So something is off it appear in my opinion.
Another Question maybe we will get a new WoJ, did a war among the Fea courts brought the end to the Dinosaurs (due to 1k years of nuclear winter, dust cover the atmosphere causing no light and warmth reach the surface ? )
