I believe the Queen created the Aura with the Harbringers. This makes perfect sense and follows the same principles as VOG. In VOG Kabr made killing Atheon possible by sacrificing himself and creating the Relic. Now TTK. At first I thought the Queen is the Aura and guides us through the entire Raid and is the one thing in the Raid that makes it possible to Kill Oryx. See the similarities? What I would like to hear from others is that Aura? (I believe this is the "hidden friend") How did it get there? Who is the hidden friend? The Aura guides us just as the Queen instructed her "Hidden Friend" to do.
