The Saint Emperor grew in that way.
As he based his growth path on the Void and tried to reach it through his own power, his entire being turned into something that would be the perfect fuel for Damien.
Damien held respect for the man, but that didn't stop him from using Devour.
No, it was precisely because of that respect that he chose to devour him.
Because the Saint Emperor couldn't die here.
If his existence became a part of Damien, he would forever live on.
And as Damien would gain everything the Saint Emperor had, he'd finally be able to understand the man without any gaps in his perception.
So he used the Authority.
Unlike the usual scene that took place, the wisps of pitch-black mana manifested by the Void gently wrapped around the Saint Emperor's body.
As it cocooned him in its embrace, he became a cluster of light particles that drifted into the heavens.
