I'm starting to realize I really enjoy it when people sneak in variations on the core canon for Exalted. I mean, we've had lots of wack things happen that aren't spelled out (the Broken-Winged Crane was our first Devil-Tiger, Pluto was his daughter and she birthed the Maidens, the Abyssals killed off all the deathlords, etc), but what I actually mean is places where something unseen in canon was the case all along or happened long in the past.
The first time I saw it was when Skeptic Tank made the Locust War happen during the Shogunate; by the time our characters showed up, Gem had been built on top of the remains of Excellent Icon of Governance/New Yugash. Perfect Unblinking Eye (Soulsteel) went on to found Paragon, and the only other Alchemical, the Jade Caste Upright Tenet of Worth, took off to the West to help people where he could.
Bystanderman is really great for these. In the first game he ran for me, my Night Caste fell into the dimension Nowhere, where things that could have happened but never did end up. It had some cool connection to Five Days Darkness and the Ebon Dragon.
In the next game, he referenced the second moon in the sky (Autochthon maybe?) and my Sidereal mentor spoke of "The Faction" in Heaven. My Solar met a handful of deathknights and Infernals but not a single Solar, and all Immaculate philosophy spoke of anathema as silver moon monsters. The story in the end was that every single Solar but one died in the Usurpation and was caught by the Jade Prison. When the deathlords and Yozi broke the prison, they got every shard, so my Twilight was actually the last Solar.
I was just wondering if you guys had any stories of vast departures from the original canon?
