In the end, if the Prince of Abolition who had helped Cheek ambush Aglaia Constantine, the Demoness of Apocalypse, was not the Night Emperor, then who had it been?
The later Blood Emperor, Tudor? Or another Sequence 1 of the Black Emperor Pathway that I didn't know about?
Tudor did have a motive... I remembered that when the Red Angel had hunted Sauron and Einhorn, he had been distracted by guarding against Cheek and ended up being "stewed" into hotpot...
Perhaps Tudor and Cheek had made a deal?
As he pondered, Abner glanced at the theater screen again. This time, it displayed a scene connected to the River of Eternal Darkness.
The image showed an ornament fashioned from gold. It resembled a slender bird, surrounded by wings formed from pale flames. Layers upon layers of light flickered within its bronze-colored eyes, as though they concealed one illusory door after another.
This was the legendary form of Gregrace, the Phoenix Progenitor.
I had confirmed before that the earliest special soul associated with the River of Eternal Darkness was Gregrace, the Phoenix Progenitor. However, after her fall, the Sefirah Imprint seemed to have been controlled by Vincent Miranda, the Lord of the Dead, before later falling into the Goddess's hands...
When I explored Observer Castle a few months ago, I saw the Projector Dead Spirit Vincent had left behind... Since he had been there, he might well have tampered with it.
So, just like the one belonging to the God of Luck, I shouldn't touch it for now!
In any case, there was a ninety-nine percent chance that imprint of the sefirah was in the Goddess's hands, so its whereabouts were fairly clear.
Having made up his mind, Abner switched away the image on the screen, revealing the final Mother Nest scene.
