Trier was already in the grip of a disaster on the level of a god's descent. If Abner used the Calamity Seal to draw on the City of Calamity's power as well, there was no telling whether an even greater disaster might follow...
After all, that Sefirah corresponded to "Calamity of Destruction, Origins of Disaster." That symbolism was no joke!
What's more, the Calamity Seal had also been deeply tainted by the Unknown. If he threw it into the "door" Roselle had built in imitation of the Night Emperor and Mr. Door, there was no telling what might happen...
Finally, according to what he had learned through Insight, throwing in an object bearing a Sefirah's aura might not be enough to control the Sefirah's power through the seal of the Gray Fog. In other words, whether it could resolve Trier's crisis would come down to luck...
So it would be best for someone bearing a Sefirah's aura to go in personally...
With that thought, Abner stopped hesitating. He took the Book of the Dead out of Alvin's Quiz Maze, pulled out a white card, and slotted it into his belt.
The next moment, rousing music rang out from nowhere:
"Transform!"
"Blessed moment...
"The supreme, the benevolent, the exalted, the mighty Death Archon—
"Lord of the Dead!
"Vincent Miranda!"
Pale light flashed. A tall figure clad in striking armor adorned with phoenixes and Feathered Serpents stepped out of the Historical Gap and merged with Abner.
The full-face armor then appeared on Abner, marking his return to his state as the Lord of the Dead.
Abner had refrained from using another Historical Projection charm even when facing the Demoness and the Divine Sword because he had been conserving his Spirituality for an emergency.
After all, he was already sustaining Lilith's Reinhardt projection.
