Yeah you could scan them with the ghost the one just though the door represents oryx the outside right was crota and the outside left was an unknown god they didn't have records on or something according to the ghost, my ghost didn't say it but my friend said it was his said it was female so that's why when she spoke about a queen after the fight I was like ooooooo maybe. This is destiny there will always be more questions then answers
Hmmm. Could there be more statues? It could possibly be Savathûn or Xivu Arath. But if one was Crota then perhaps the other was one of Oryx's daughters. I always look for symmetry in these things and the obvious suspect is the Mother of course.
Form Verse 4:6 - Eater of Hope:
"You are Crota, my son. Welcome.
I fought my way out of hell to make you. I fought my traitor siblings and I fought the swarming corpse of Akka and I cut my way back into my own court, the High War, which had been usurped. Once I had made war on Savathûn, and crippled her tribute so that she could never challenge me, and once I had tricked Xivu Arath, and poisoned her tribute so that she could never again try to take my tablets, and once I had arranged my own lineages so that I would be greatest among the Hive and secure on my throne — then I found a mother to make spawn.
One of those spawn was you."
It is never revealed who the Mother is. Unknown, female Hive... she fits the bill I'd say
