The reaction that El'Rion might have expected wasn't the one he received. If anything, he was underwhelmed.
Leonel had already seen just how far apart the strengths of various Races could be. Setting aside the Spirituals, there was himself. When that figure in the blood pool moved, it had to be understood that Leonel's Dimension didn't change, the only thing that changed was how much access to his own personal talent he had. That meant, the man who could kill Ancestors, and even Overlords, as though they were wet tissue paper, had been the very same Sixth Dimensional Leonel.
Of course, that was still not as impressive as El'Rion who was only in the Fifth Dimension. Though the latter had said Quasi Sixth Dimensional, this was the reality. Quasi or not, it was still the Fifth Dimension. However, it wasn't enough to completely upend Leonel's reality.
