But it doesn't fit. You use tadpole powers. You dream the dream lover. She gives you greater tadpole powers. You use them. She returns in your dreams and increases your transformation. You are gaining more illilthid powers. She promises you the ability to rule at her side. All of it is illithid based. It's not gith. You are becoming a very powerful true soul.
I don't know. It would be kinda weird to be the weapon. That would mean that a gith weapon was using mind flayer powers, harnessing them and honing them. Wouldn’t that be an abomination to them?
Are all the powers necessarily illithid or tadpole related? I had always assumed that they were, and certainly the dialogue options specifically say “illithid” but perhaps it’s more complex than that. Gith also use psionics, or perhaps the sentience in the box is something else entirely that nevertheless can manipulate illithid-like powers. We don’t know that the gith created what’s inside the box, even if they did create the box itself.
I agree not everything perfectly fits the idea that the dreamer is related to the box, but we know so little about it that those could still be explained away. As could potentially the things that don’t fit about the dreamer being on the side of the Absolute, such as the fact the tone of the dreams is entirely different from the vision of the Absolute, that the box responds to that vision but not the dreams, and that in that vision the voice is asking for help finding the weapon which the dreamer doesn’t ask about.
It still feels as though there are loads of ways this can go, and it’s fun to speculate.
EDIT: By the way, I don’t think that using the tadpole, assuming that’s what we’re doing, is *necessarily* what the Absolute would want, either. There’s presumably a reason why the cult have been set to kill survivors from the ship. Perhaps they actually don’t want people going around using the powers without having completed the full process that involves forgetting about the tadpole.
EDIT 2 (ANOTHER QUESTION): By the way, do we think that the vision of the Absolute as we enter the goblin camp is targeted specifically to us, or is it being broadcast to all True Souls and we happen to get caught up?
