A dream visit from Sehanine is an interesting idea (Or whatever deity saved you from that fall when you fell out of the nataloid). They could kick off a convo after the fall cutscene with a more trusted but vague source... I like it. However, that would be a lot of work for Larian and critics would be fast to point out the parallels between Divinity 2's prologue and BG3s.
So while there are some excellent ideas, personally I prefer to focus on the simplest solutions, Adding cut-scenes is complicated business. Altering existing dialogue is much easier. Especially if you are simply truncating an existing line so that certain things are simply not said. The good news is a solution that simply cut certain lines short and removes other lines would also be ease to do as a mod. And as a modder, if Larian doesn't address this, I would probably make that mod myself. But... I want this game to do well and not everyone installs mods. So I would prefer in this case that Larian address the issue themselves.
So anything would be welcome. A dream visit from a god. Making NPCs say less... or more. An elder tablet that you pick up to get the codes needed to open the door to the nataloid and the narrator tells you about visions of thralls being kept awake to maximize the parasites progress with the host. Other ideas are welcome.
