just curious. That floating orb of light that is played off as something of oryx leading us along from our first mission. Could that instead be somehow the queen? There is for sure more to come in this story though one way or the other. I also think you have the story correct with the queen and Eris.
Couple of Toland quotes:
“I too, am detached from my source. The charming Ir Yût made her introductions, and I was very pleased to meet her. We had a conversation, a little tête-à-Yût, a couple of old wizards exchanging definitions.”
"Now I fly between green-black suns in the labyrinth beyond Crota’s god-star. This is the Overworld, the Sea of Screams, where the throne-universes of the Great Hive fester in eternal majesty. I move among them. I map the shapes and connections of this world”
Which sorta led me to believe that light may be what is left of Toland
