Viewing post in Stuck in the Underdark with S'rami
Mirimiel is supposed to appear after S'rami's mother is no longer a statue and you leave the strange room. Then you're supposed to ge back to the Underdark City with the two of them. Then you should be able to access the Dark Elf pub and talk to of the npcs and it should trigger the next chain of events.
