It is a world of darkness… With the principal demon vanquished, the October Gathering saw some strange and unfortunate events.
The bulk of the Sword of Caine were defeated and slaughtered. Some escaped to try and find a way to re-summon their dark master. A rare few surrendered and were either welcomed back by their Shield of Caine brethren or given sanctuary among the Camarilla or Anarchs. That these few individuals had unique abilities, rare lore, or juicy blackmail was surely a coincidence.
Although some naively sought peace, the pact between the Shield of Caine and other Sects quickly started to dissolve. As the Sabbat reclaimed the Sword of Caine as their banner, old grudges set aside once again heated up. The Sabbat of any history were once again unwelcome in Atlanta.
While all this was happening, Don Giovanni saw his opportunity to realize a long-lived dream of turning Atlanta into an unliving Necropolis. Members of the Domain were dispatched to halt his necromantic plan.
Simultaneously, a small Pack of Sabbat still loyal to demonic forces had gone grave robbing. Another team was dispatched in order to prevent the war from returning.
Don Giovanni was able to begin his ritual and the Sabbat were able to sacrifice themselves to bring back a weakened form of their prime master. Despite this, the Kindred of Terminus fought hard and were able to put down both Don Giovanni and the Demonlord.
If only one of these things had occurred, as happened with the demon lovers in other Domains, perhaps the fallout would not have been so bad. Unfortunately, the backlash of both partial rituals, as well as the death of two powerful beings, led to a supernatural backlash.
It seems to have only affected supernatural creatures. But most Kindred in Atlanta died. Some quietly, some laughing or screaming, and some exploded where they stood. The rest were rendered in some painful and horrifying manner, with eyeballs exploding or the strength of their blood being attacked.
To prevent the power vacuum from leading to an all-out war, the Inner Circle and the Anarchs met and agreed to settle the area quickly. Powerful Kindred ejected from their own Domains and Territories thanks to their own Sabbat summonings were sent to maintain peace and order in Atlanta. How long they hold those positions and can maintain the status quo is anyone’s guess.
