Yes, there should be more references to what has happened to us, in camp dialogs, if no where else. Did we have friends in that town, etc.
I seriously missed something haha, what town?
We are taking about the cinematic where the ship fly over the town, snatching up people. I am assuming that where we got picked up but now thinking about that why would a Drow be there? I have no idea where my Drow was snatched from.
Anyway, the background is at the beginning the ship is snatching up people to then implant these modified tadpoles in.
You are right that it is not just the town show in the cinematic because we have Goblins and Minthara with tadpoles. The Mindflayers must be snatching people from several areas.
I can answer the drow bit.
By this point there is a significant population of drow living on or near the surface. This includes both Seladrine Drow and Vhaerun-worshipping Drow.
4th edition storyline had an event were a large portion of drow were re-accepted back into the Seldarine which resulted in them returning to their original skin colors among other things. I personally didn't like that bit of story which came along with the deaths/removal of Vhaerun and Eilistraee, both of whom I find as more interestingly developed gods than Lloth. It was basically an excuse to remove not-Lloth drow by declaring them no longer drow. With 5th ed, they've brought back Eilistraee and Vhaerun. I personally would still tend to stat the Seldarine Drow as Wood or High Elves (because they've been on the surface for a couple of generations mostly) but they are culturally in the lore considered drow again.
But to summarize up, there's a significant minority of surface dwelling Drow in the Sword Coast regions. If your Drow is Lloth-sworn....that's another question entirely....but with the growing number of openly existing surface-drow communities it is likely that Lloth-sworn have started sending spies up.
