Ren closed his eyes, remembering what he'd seen through the Mantis's eyes in those final moments before destruction.
Two hollows, one filled with a pulsing crystal that glowed like a heart, the other empty and waiting. And Sirius's chest with that hollow at half depth, incomplete somehow.
What was missing…
Ren recognized that system because he'd created one for the egg he'd given Luna.
The Celestial Tiger's system.
Sirius's Gold-rank beast was the one crystallized in the door. Not the Black Serpent.
That meant something. Had to mean something significant about the door's requirements or Sirius's situation.
Did the door need a Gold-rank beast in each hollow? Julius and Selphira had Gold beasts too, so maybe they hadn't approached because they knew what would happen if they tried to open it?
All this had left Ren with more questions than answers…
Always more questions than solutions, the universe mocking his attempts at understanding.
