For this one, I'm 100% sure you get a very small dialogue option with Orpheus, who will dismiss it because he doesn't trust you, and doesn't know what the Netherese Orb is. I think you need Gale in the party, talking with Gale within the Astral Prism isn't necessary
Should this have been a completely viable option? Probably, yes. Its one of the moments where a high difficulty persuasion check would have been highly appropriate, but Larian really didn't want it to be a true option.
Yes that's the problem: Mindflayer or mindflayer?
- Withers: why?
- Ghithyanki people arc
Both of these are likely to create hype for a definitive edition, or a sequel.
I am not that optimistic to be honest: They have too much to fix to add a lot of new content, while a sequel... well by the time they make it everyone would have forgotten this forgettable main story so any BG4 would probably start fresh.
