Thing is, technically he hasn't really enthralled her?; if we're going by her description her mind is still there but chained except when working together, being enthralled would mean she had her mind blown out and rewritten into whatever the emperor wanted it to be which is what makes them great spies. But he didn't and kept her around collaborating with her for over a decade. The extraordinary circumstances in the very least do make them long time collogues and friends in the technical sense or, if you like, in the worse case the emperor totally enthralled her, still yes, they are totally bffs and whatever more he likes because he rewritten her mind to be just so. At the very least not technically lying.
Aside from Astarian (only triggered once), Gale 'eventually' coming clean is still being forced by the fact he can't suppress the bomb anymore, Were you in romance with shadowheart? I'm pretty sure she never reveals stealing the prism until laezel calls her out on it Also Wylls can't talk to you about his contract, not the fact he's sold to the devils; mizora even tells him he was naughty for not telling us about her
"Robbing Gith race of their future" is hilarious because the githyanki want nothing more than to have world spanning empires like the illithids and enslave everyone. The souls thing is new, cause other sources dance around it aside from mind flayer liches, still required to craft and trap in a phylactery. But its larian's story so we have to go with that.
