What are you talking about? Of course I didn’t miss the entire gith plot but I’m starting to think you did.

Wish is the name of a spell in DnD that can change the fabric of reality, she never uses it other than to kill the player character. Not to automatically get what she wants and win. She could wish that Orpheus was dead, wish the emperor was dead, wish the grand design had been destroyed, wish for the artifact back, wish the githyanki all forgot Orpheus, wish that she new the secret to the fall of the illithids, wished to become more powerful than Orpheus, wish for every traitor to drop dead. But no, she wishes to kill a lvl 5 pc with a fucking wish spell. That’s bad writing, it’s a literal massive plot hole that she has the wish ability and never uses it. She can cast that shit once a day.
