Metamagic
- Postulate of Invariance
- Axiom of Least Contradiction
- Verity of Exclusion
Metamagic is the art of manipulating the laws that govern magic itself, that is, the seven rules listed above under the other schools. It is the principle focus of Secret of the Sixth Magic, wherein it is discovered/formulated (which may explain why no associated aphorisms are given, due to its newness). Wielding Metamagic involves suspending the current rules, replacing them with new rules, and reinstating the rules—the greater the skill of the Metamagician, the greater the difference between the old rule and the new one may be.
The Postulate of Invariance states that there can only be seven rules governing magic; the Axiom of Least Contradiction states that the seven rules that are in effect are those that best match the (non-magical) effects occurring during periods when the rules are suspended; the Verity of Exclusion states that those who are capable of wielding Metamagic are inherently incapable of wielding any other magic and vice versa.
