I'm back. There's a few changes in New York. A.I.M. has always owned the Tower in Tribeca, where you all once lived. I learned that the hard way after I portaled in. Qeng Enterprises appears to own the oldest Avengers Tower, too. That's different than before.
The Sanctum hasn't moved. Nothing has changed at any Sanctums. This Earth is still protected from interdimensional and mystical threats. And despite all of these breaks in our reality? This universe remains fractured but whole.
Before anyone asks where I was: it's hard to turn down a summons from the patrons of the Mystic Arts. They wanted me to take part in a 5,000 year war on another plain of existence. It took some time not to piss them off.
