Prime Energy Classes

The following energy classes form the metaphysical basis of magic.

In theory, a spell may draw mostly from a single Prime energy class.

In practice, many real magical workings are compound. A stable effect often requires:

Because of this, the Prime energy classes should be understood as the deepest layer of theory, not always the most practical everyday language.

When a compound spell draws from two or more Prime classes, each class is evaluated independently against the caster’s affinity for it. A caster with strong Ignis affinity but weak Aqua affinity working a fire-healing combination handles the Ignis component cleanly while losing significant energy in the Aqua component. Both losses are real and both count toward the spell’s total cost.

The weakest individual affinity in a compound casting sets a practical ceiling on the working’s overall stability. A single low-affinity component can destabilize an otherwise well-controlled spell, because the caster cannot govern what they do not feel.

Specialists therefore remain efficient within their domain even in compound casts. Generalists bear moderate loss on every component. No inherent advantage favors pure casting over compound or vice versa; it depends entirely on the caster’s actual affinity profile.

For cross-school and cross-method adjudication, conversion outcomes are evaluated by tiered qualitative bands rather than fixed universal numbers. This keeps doctrine consistent while allowing institutions to apply local standards.

A pairing becomes inherently unstable when the core functions of its component classes directly contradict each other. Contradiction arises from opposed directionality: one class drives a process while the other resists, reverses, or erases it in a way the energetic system cannot reconcile.

Unstable combinations do not fail cleanly. They function — but the unresolved tension produces involuntary side effects, and the working scales unpredictably. A small casting may barely register the instability; the same pairing at greater power may spiral well beyond the caster’s ability to govern.

Three pairings are canonically recognized as resonant oppositions:

These pairings are not forbidden. Practitioners have built disciplines around managing them. But they demand high affinity in both classes, careful method selection, and the understanding that the working will always cost more than a clean, compatible combination would.

Beyond resonant oppositions, certain pairs are recognized in established theory as either naturally harmonious or naturally resistant. This is a matter of energetic compatibility, not moral judgment.

Harmonious pairs have complementary core functions. In practice this produces lower energy loss per component even at moderate affinity, greater combined stability than either energy would achieve alone, and a tendency for the working to consolidate itself under pressure rather than fragment.

Resistant pairs produce waste rather than instability. Their functions do not oppose violently but fail to reinforce each other: energy from one component that neither class can stabilize simply dissipates, increasing cost without proportionally increasing power.

Canonically harmonious pairs (well-established in received theory; not exhaustive):

Canonically resistant pairs (well-established in received theory; not exhaustive):

Note: Aion + Ignis and Lux + Umbra also appear among the resonant oppositions above. The two categories overlap: all resonant oppositions are resistant pairs, but not all resistant pairs produce the involuntary side-effect pattern characteristic of resonant opposition.

Several compound pairings are recognized widely enough that they have accumulated common names and teaching lineages. These are not formal schools — cultures may classify them differently — but a practitioner who names one will be understood in most contexts.

This classification is important because it:

If a spell cannot be explained in terms of one or more Prime energy classes, it likely does not belong cleanly to the current system.
