Interesting question and some interesting interpretations but what about
Isobel who is getting her mojo from Selune in the inn (and doesn't want to go with Marcus) but has an empty sarcophagus in the Thorm crypt and then shows up at the Ketheric Thorm fight (and still calls on the Moonmaiden for aid).
Nightsong who is she and where does she fit in? Nightsong, Nightsong, find the Nightsong. So you find the Nightsong and
1. She is killed by Shadowheart - are there any repercussions? Or
2. She is freed and she zooms off to attack Moonrise except that the next time you see her she is a captive again.
Why does the description of the three figures you get in Act 1 describe Goulash as a handsome you elf yet when you meet him he looks like he been living rough and and has a hangover of biblical proportions.
What's in it for the three stooges if they turn everyone into mindflayers?
Why can Winged Horrors fly in the attack on the inn but in the illithid colony under Moonrise you can push them into the chasm and to their death.
Tune in next week for more thrilling adventures . . .
