Beast From Far Beyond

Last session, the party was face to face with the Emperor in the middle of his ritual. In between them were the children, weapons at the ready to slow the party down. And they were successful. The party was not even able to touch the Emperor as he finished the incantation. The world turned to dust around them leaving on the party to deal with the true form of the Beast From Far Beyond. Standard methods of harming the Beast does not work anymore. They had to coordinate their action so that the Foundation of the World artifacts end up within the body of the Beast before it could react to their defenses. When they succeeded the party as tossed off to different planes of existences, leaving them separate but with a familiar being ahead of them. The Emperor.
