It was a tier 7 spell with the power to cut through space itself.
The technique could be considered Grand Magus Zenonia's inheritance, which Emery received when he devoured the female Grand Magus.
Over the past 15 years, as Emery's primal core slowly recovered and his understanding of the law of space had deepened, this formidable technique, along with the terrifying tier 8 spell [Black Hole], had become integral parts of his hidden arsenal of spells.
However, despite their potency, both spells were considered incomplete—each marred by missing and broken runes that Emery had been trying to fix over the past few years.
Note: his primal core has not yet fully recovered.
