"A wizard's power came from knowledge, from an understanding of the world."
"This power was objective, reproducible, and beyond doubt." As Angel spoke, he gently raised his right hand, a patch of light resting in his palm. "Take this Light Spell, for example. It is the lowest-level cantrip, yet it contains the energetic essence of the wizarding system."
"In the Southern Region, it was called the Light Spell; in the Eastern Realm, it was called the Glow Spell; in the Northern Territory and Western Continent, it was called the Radiance Spell."
"The names differed, and the effects varied slightly, but the foundational model used to construct this cantrip pointed toward the same principle."
Angel extended his left hand and constructed a peculiar geometric framework in his palm.
"This is the cantrip model of the Light Spell."
"As long as one makes slight alterations or extensions based on this model, it is possible to..."
Angel gently blew at his left hand.
Several new nodes appeared on the geometric model, automatically linking themselves to it like building blocks with matchsticks.
When the new matchsticks were added to the model, the Light Spell in his right hand, which had originally emitted a faint white glow, turned into blue light like cold fire. The bright warmth brought by the previous radiance also became several degrees more bleak and chilling with the shift in color.
"See? With only slight changes to the model, the manifested effect of this cantrip can be altered."
Then Angel blew several more breaths.
The cantrip model in his left hand continuously sprouted new "little matchsticks." At the same time, the Light Spell in his right hand changed from a beam of straight light to rainbow light, then became blazing like the Sun, then cold and silent like phantom light...
