 * Evelyn gets pulled into the Astral Plane and finds the C Team battling the Sanguilith. She tries to help them but her attacks get redirected onto her allies after Lathander gets taken over. She then gets sent back to the Material Plane before the C Team finally vanquish it, releasing all the trapped gods.
 * The Acq Inc team finally leave Ravnica, only to find themselves in Avernus. They run into the Jim Clone, who is now a lich and a warlord, calling himself 'the Real Jim Darkmagic'. Somehow Evelyn was also transported there, and was forced to watch the lich's magic show over and over.
