The story between her and Sandrah starts with Tarnesh even.Yeah, k, make *Tarnesh give the speech* if Imoen is any kind of mage, the how she got it, aka what you chose during the Imoen speech in the start in Candlekeep was, there doesn't need to matter AT ALL ! Does it ? She could be a 20th level thief and 44th level mage, but if you prevent a check being made there... life won't go on as it could if you just bothered to check for it. Same as if Gandalf wouldn't have bothered to return to his old friend birthday party, he wouldn't have "inspired" the 4 hobbits to go toward the human village, and soon the whole would have looked a bit different. With a nice Orc army among the hobbit town rebellion, or what ever.
*plot point* be it what ever it is. Does the Bhallspawn want Edwin to be a non evil, make the talk allow you to choose, and make the quest starts to check for needed patterns, not non essential other choices that might had made sense in the scenario where the train never stops between the start and end spots.
Of course if Tarnesh ends up dead before he meets Imoen the mage, the quest never needs to start, it is the unseen hand of the killer that opted this option and he can learn to live with it. .
