Is there any way Taox could be Eris? How else would she have three eyes other than if she was a member of the humanoid krill species that didn't get corrupted into the hive? I always thought it was strange that being trapped on the moon caused her to become part hive and grow two more eyes. What if she had them to begin with? She's evidently a major player in the story with her dialogue both in game and in grimoire with the queen. So is it possible? Do we have grimoire confirmation that she was human when she went down into the pit? There is clearly a strange psychic connection she has with Oryx.
