Kan'na was full of question marks.
Her mentor hurried to explain, "Runes are mere instructions and connections for mana to follow. These these are laws!"
"I don't understand."
"When we create a spell we write runes for mana to follow. This instead forces the mana to follow its command, or in this case law."
"How is that any different?"
"Rune instructions have set rules to follow for the mana to flow properly. You can simply do whatever with this."
Kan'na raised an eyebrow, "So it's runes without rules?"
"No it is the rules."
. . .
Kan'na spent the next couple months testing the limits of these new runes. With extensive research she had figured out the limits and behavior of the runes.
She could do anything she wanted with them on a minor scale, like when she separated the mana types. However on a larger scale they followed a single rule. It has to be for all.
