When I was thinking about the Illithids having maybe an overarching aim with their targets, I was mostly thinking Doppelgangers plot in BG, they wanted nobles dukes etc but they're not being too discriminate...poor Phydia. I think the machinations of the Absolute and the Mind-Flayers aren't the same, so some people are for them and some are for the cult.
I'm not too upset by our parties, 'specialness' because at this stage I'm reading into a lot of their backstories and looking for ways they might be related to our main storyline. Lae'zel is easy, Shadowheart too, I might be spoiled on who Cazador is, and as for the others, we'll see.
As for Tav, well I've had thoughts on it
already, basically I'd like to be given tools that allow me to incorporate a MC better into the world. A prologue for every character being my best case scenario.
