Expedition to the Burrow World IV

This subtle and cool black energy was oh so familiar to Grimm.

He recalled the time when he was still a sorcerer-apprentice, at the final stage of the Eternal Darkness Territory at the ingenious Tower of Ruins. That, and the materialized spiritual energy of the Nightmare Shadow sealed within the Sabbatic Goat Staff he was holding in his hands at the moment.

They all emanated the same aura as this pure black giant's phantom.

After a few pauses to recoup his strength, Black Isotta finally struggled his way out of the crack and descended upon the Sorcerer World.

At this moment, the Stigmata Sorcerer had completely transcended the pressure from the higher life levels of the official sorcerers. All restraints were dropped as it cast a vast shadow so great that it could cover the entirety of the sun's rays.

This overwhelming feeling of pressure was like a cane that whipped down hard on Grimm's heart. His entire body trembled as though it went into a brief seizure.
