"Yes. Thanks to that, we were able to find the foundational formula the entire Castle of Separation was built on. Though confirming the contents and building our own answer to it took a considerable amount of time.”
“‘Build’ an answer?”
With a gentle smile, she opened her hand, revealing a single jewel.
"All the rooms, all the hallways…all the Magic Circuits running through the Castle are now buried in this jewel. It took me almost half a day to finish.”
My master’s eyes went wide at the realization of what that meant.
“Wait, you don’t mean…”
“Precisely.” Luvia’s face bloomed into a sweet smile. “I’ve decided to take the Workshop that is the Castle of Separation for myself.”
Just hearing her say it aloud left me speechless.
She was like a parasite.
Or maybe closer to the computer viruses I had heard about since coming to London.
Even I, who knew next to nothing about magecraft, could instinctively feel the dreadfulness of those words. A Workshop was something a magus created after years, decades, generations of labour. If a Magic Crest was an artificial organ, then a Workshop was like an artificial world.
It was a method of pure brute force. While my master attempted to break everything down and solve every mystery of the Castle, even if it was as a magus, Luvia had taken on the entire Castle at once in half a day.
It was like Don Quixote, taking up arms against a windmill.
