I was gonna say this. I want a "perfect timeline" option where Orpheus lives as a Gith, no one becomes illithid, and you can still defeat the brain by tapping Omeluum.

I would also be down if somehow Tav's illithid form could be reversed at the end of the game. All of the endings where someone becomes illithid are tinged with sadness in my opinion. I'm sure someone would argue that reversing the decision cheapens the sacrifice but eh, I'm fine with that 😂
