Ronin had entered the Silva Magic Energy Chamber of Commerce to shop, but that didn't prevent him from gathering plenty of information along the way.
And Hook, eager to close the deal, told him practically everything he knew and was permitted to share.
Besides the prices of various goods, Ronin discovered something interesting—Demon Cores.
As he understood it, a Demon Core was the source of a Magical Beast's Magic Energy, functioning much like a battery. After Hook's explanation, he gained a deeper understanding of their purpose.
Demon Cores were crystalline. Even when ground up, they remained granular and could still react with Mana, which was why they could be used as an ingredient in Mana Ink.
Furthermore, when a Mage used their Spiritual Power to perceive an intact Demon Core, they could sense the Magic Patterns within it.
These Magic Patterns were the key to a Magical Beast's ability to use Magic, and also the origin of how early Mages came to master them.
