"Magicules are basic magical particles that permeate our world," Mari explained as she picked up a thick book from a shelf filled with several others. "Magicules are believed to be the essence of magic, the source of power that magicians and wizards manipulate to perform extraordinary feats."
She opened the book and showed Victor a simple illustration of a magicule, depicted as a small glowing sphere surrounded by a vortex of energy. The structure was similar to the atoms Victor Shieldman had seen a few times at his school on Earth, but the core was intensely bright, like a ball of light.
