The Fall of Emon

This is when the Chroma Conclave invaded and destroyed part of Emon, triggering the start of the Chroma Conclave arc.
Directly before the Chroma Conclave showed up, Uriel Tal'Dorei was in the process of stepping down and forming some sort of parliamentary system. It is unknown if this was related to the timing of the invasion, but it probably wasn't.
Shaun Gilmore was conspicuously missing during the invasion (this was called out by Matt), despite him having walked to the event with Vox Machina. It hasn't been clarified where he was to my knowledge. Shaun Gilmore did mention dueling Thordak at some point, but this would either have needed to be after Vox Machina ran to Greyskull Keep, or somewhere else.
During the invasion, Umbrasyll and Thordak were seen in the sky, then Vorugal was seen destroying Allura Vysoren 's tower, and then Raishan came over the wall and confronted Vox Machina .
The dragons then continued eastward towards Westruun and fucked it up. Seemingly Umbrasyll stopped at that point.
We then have word of Vorugal taking down the floating islands of Draconia. Raishan likely stopped at some point between Westruun and Draconia, probably somewhere in Wildemount?
