Time

The old man's logic was simple. Dyon was a mortal. It was impossible for him to have transcended and still retain his mortal body. Even those who managed to perfect their mortal bodies on the mortal plane were simply gifted high level immortal bodies in return. They would retain their constitutions, but they would ultimately still be immortals. 

Such transcendents were incredibly well respected. They didn't face the same stigma mortals and lower level transcendents did. 

"… I would have sensed it already if she transcended. This means that she hasn't." 

"What did you just say?!"

The old man's calm demeanor cracked. The weight of such words was far more than they seemed. They all but confirmed that Dyon was a transcendent. But how the hell could a transcendent have a mortal body?!
