This is about the ending of SoA/start of ToB, so you might not want to read this unless you`ve played so far yourself.

After killing Irenicus in the final battle and the ceremony in the temple with Ellesimes speach, my party was transported (after the cinematics) to the "Ancient place with the stone heads" in ToB where Illessaire should attack you. My main char, a level 20+ Monk however, was not transported there and was stuck in the temple. Talking to Ellessime resulted her repeating the speach (no more Amulets of the Seldarine however) and the cinematics. Nobody else wanted to talk to you, but you could leave the temple and walk around Suldanessalar (where Elhan was still telling you to go kill Irenicus), but not re-enter. After I got the rest of my party (who had transferred to ToB) to talk to the stone heads, Illessaire appeared in Suldanessalar and attacked my lonely monk (much to the annoyance of the rest of my party, which had filled the ToB area with Delayed Blast Fireballs and Elementals ). I killed her pretty easily (I had already gotten to level 4 of Watchers Keep after all) and was then happily reunited with the rest of my party in the Pocket Plane, after which things went back to normal (or how normal things can be when you`re the son of a god and you`re trapped in the Abyss with a Solar greeting you...).
