Firstly, the Awoken were born from the Collapse, from when the Traveler died, the combination of Light and Darkness created the Awoken, "the Awoken are my family now", " I still bear the scars", meaning that the Awoken weren't always her home, something cataclysmic transformed the Awoken, possibly indicating she is a "firstborn" Awoken. "Our beautiful creation", that is her family-the Awoken, the Reef. Eris is most definitely human, and she has probably developed a relationship with the Queen prior to the battle, she obviously knew her at the time she asked Mara to help end Oryx, but Eris is human. "All part of the plan". Mara knew more than she let on. She knew, or at least guessed she would not win the fight around Saturn. At the last bit of her saying, " Guide them, my Hidden friend," she is talking to Eris, as she is known to be part of the Hidden. Eris having powers we don't yet know? Possibly, that Orb she carries speaks to her in some way. I'll have to disagree with Cliferhex on the Taox theory. She didn't have three eyes before she went into the Pit, she also had a Ghost before going into that Pit. The Krill evolved into Morphs, such as the Knight, Mother, King, etc, not simply a cloak to their appearance, and Taox is a mother morph, meaning she would look similar to a wizard.
