I had the opportunity of interacting with Arcanas before.
While I didn't have any Magic back then—since I was Inept—I was able to understand the fundamental structure and code associated with the items.
Of course, it was only surface-level knowledge.
What I researched was not the Magic in the Arcanas, but the items themselves. The ones I saw were in the form of cards, and they had vein-like circuits embedded in them.
It was a mystery how such small things could hold phenomenal powers, so I buried myself in the research.
I wasn't able to complete the project, but it was enough to figure out the fundamental rule of storing Magic in these items.
When I started attending Ainzlark and then found the Oasis, I figured it would be good to try something like that—as a last resort.
And so, I pumped lots of Mana into the thing, reinforced it by condensing the materials used to manufacture the item, and made a gradual assimilation process.
If I was too fast, the project would fail.
