The Incantation Hub, a special type of Control Core, was both a home for the soul and the spellcasting core for the Puppets Allen would design.
Miniaturization was an unavoidable hurdle.
Gabriel's Incantation Hub was, in essence, a "Magic database" that relied on six book-sized Rune Boards. To shrink it down to a Puppet's scale, each Rune Board had to be compressed to the size of a playing card.
This meant that the precision of the Rune inscriptions needed to increase by an order of magnitude.
Fortunately, Allen could solve this problem with the "Miniaturized Parallel Rune Inscription Technique" he had learned from the Association's knowledge base.
But he soon discovered a new problem.
After increasing the precision, the number of Runes per unit of area skyrocketed, and the Magic Power interference between them rose exponentially. It was like a highway jammed with tens of thousands of cars, where a chain-reaction pileup could happen at any moment.
