The formation's transmission within the light barrier was exquisitely intricate, enough to make even you marvel and itch to study it. But this was clearly not the time to research formations. The greater matter came first.
Fortunately, the Double Pupils were innately wondrous, and since you yourself were proficient in formations, having witnessed the bronze mirror vanish with your own eyes, you had memorized the entire process by which it triggered the formation and transmitted itself away.
