Pneuma

Pneuma is the animating spirit of the world — breath, life-force, and the fuel of all magic. Everything alive contains it; to be alive is to carry pneuma. It is both a collectible resource and the foundation of character progression.

The Three Laws of Pneuma

Long before scholars gave it a name, every breath-worker's first teaching held the same three truths, and no apprentice has yet found cause to doubt them.

I. Vitality. Pneuma is the force that underlies all life. To breathe is to live, to live is to breathe — they are one and the same.

II. Attrition. No shaping of pneuma is without loss. Pneuma may be imbued with an element, and imbued pneuma unmade back into pure, but nothing crosses that threshold whole — the deeper one's affinity, the less it leaves behind, but never nothing.

III. Affinity. Every element embraces its neighbor and attacks its opposite: what is close may be joined, what stands in opposition, forced together, unmakes both, leaving nothing but breath beneath them. So too an element draws close only to the one who spends it, and remains a stranger to the one who merely holds it.

I. Vitality

It is why a mountain spring runs cold with both water and earth at once, never one alone; why a slain salamander gives up fire enough to warm a hand, though it lived its whole life on nothing grander than insects and shade; why even the stillest hermit, who has never lifted a blade nor spoken a spell, wakes each morning a little fuller than the night before.

II. Attrition

An alchemist who forces fire against flood in a crucible is left with pure pneuma, always less of it than the two elements held between them — the loss is not a debt owed to anyone, only the price of the crossing itself. It is the same toll paid when pneuma is drawn from a vent into a body, or unmade from pure into a spell: some part is always spent on the shaping and never seen again. No teaching, however deep, closes that gap to nothing.

III. Affinity

A flame held near a gust becomes a storm's lightning; held near stone, a forge's magma. But hold flame against flood, or wind against mountain, and neither survives the meeting — only breath remains, and less of it than either side began with.

So it is between a breath-worker and the elements they touch. One well-versed in fire draws deep from a vent that leaves a stranger with almost nothing for the same reach; and to call that breath back out again, shaped as fire or frost or storm, costs less and carries further the closer that bond runs. The bond itself is built only one way — by spending, never by holding. This is why the deepest fire-sworn in the world still kneels at a vent before battle, and why no buyer of pneuma, however rich, has ever purchased their way into closeness with an element: coin buys the breath, never the affinity to shape it.

Forms

Pneuma exists in one pure form and four elemental flavors it takes on when steeped in the world:

1. Water
2. Fire
3. Earth
4. Air

Pure pneuma is the unflavored animating spirit itself. Life is not a fifth element: healing, growth, and other "life magic" is pure pneuma work, since mending a living thing means handling unflavored spirit directly. Earth is cleanly stone, soil, and mountain.

By Law 3, a person never carries elemental pneuma internally — only pure. Elemental identity lives in the world (sites, creatures, condensed crystals) and in a person's mastery of each flavor, never in a body's own reserve.

The elemental square

The elements follow the classical (Aristotelian) square of qualities (Law 1): fire is hot+dry, air is hot+wet, water is cold+wet, earth is cold+dry. Opposites share no quality — fire↔water, air↔earth. Neighbors share exactly one, and only neighbors can combine:

Element	Qualities	Opposite (annihilates to pure)	Combines with → hybrid
Fire	Hot + Dry	Water	Air → lightning / storm-fire; Earth → magma / forge-heat
Air	Hot + Wet	Earth	Fire → lightning / storm-fire; Water → mist / ice / tempest
Water	Cold + Wet	Fire	Air → mist / ice / tempest; Earth → mire / clay / the deep places
Earth	Cold + Dry	Air	Fire → magma / forge-heat; Water → mire / clay / the deep places

Laid out geometrically, neighbors sit adjacent and opposites sit across from each other:

                 FIRE
              (Hot + Dry)
               /       \
        EARTH             AIR
     (Cold + Dry)      (Hot + Wet)
               \       /
               WATER
            (Cold + Wet)

Hybrids stay physical. Water+earth is mud and clay, never "growth" — verdant life magic belongs to pure pneuma, not to an element pair.

A hybrid spell consumes pneuma of both parent elements, and its mastery feeds both attunements. Hybrid casters are naturally neighbor-pair specialists (the storm-caller and the frost-caller share nothing), with no extra machinery.

Opposition

Opposition lives in the world, never in the soul:

• Annihilation. Opposed pneuma forced together cancels its flavors, leaving pure pneuma at a loss. This is a craft, not a cast: anyone can force two opposed typed items together — an alchemist's bench, not a caster's own body — and it requires no attunement at all, because Law 3's mastery only governs a person's own drawing-in and shaping-out, never a reaction between two inert items. Annihilation is how pure enters trade: it cannot be node-harvested directly, only refined this way or generated by a person's own effort.
• Interactional counters. Counters are verbs, not percentages: water quenches burning effects and extinguishes fire walls; each element counters exactly one and is countered by exactly one. No flat damage multipliers.
• No attunement opposition. Deepening one element never impedes its opposite (Law 3: mastering one flavor never costs another). Mastery of all four is honestly achievable — the ledger already prices it; no wall is needed.

Where pneuma comes from

• Elemental sites and nodes. Typed pneuma is drawn in at places where an element runs strong — springs, vents, groves, currents. Abundance is a gradient, not a zone: everywhere has some of everything, and sites shift the local mix. A mountain riverbank yields both water and earth. There is no "fire area."
• Creatures. Everything alive carries pneuma and releases it when slain. A fire spirit yields fire pneuma — it was life-stuff steeped in flame. An ordinary animal yields a trickle of pure. Drops are not arbitrary currency; you are releasing what animated the creature.
• The self. Every character slowly regenerates pure pneuma just by being alive (Law 2) — their own breath. Deliberate practice (exercise, meditation) can push this harder than passive regeneration alone, though it remains far less efficient than engaging the world or the market.

Carrying pneuma: the pool

A person's own reserve is a single, unbounded pool of plain pure pneuma (Law 3). There is no separate reserve per element, no capacity to grow, and no cap to hit. What varies by flavor is not how much you can hold, but how efficiently pneuma moves across the boundary of your own body in either direction:

• Absorbing. Drawing typed pneuma out of the world — a crystal, a vent, a fresh kill — and into your own pool always converts it to plain pure. How much pure you get out of a given amount of typed pneuma is set by your mastery of that flavor: a fire adept draws deep from a vent that leaves a novice with barely a trickle.
• Condensation. Pneuma also moves between bodies and vaults without ever entering a person: typed pneuma condensed into crystals or vials (or pure, refined by annihilation) is inert, storable, and freely tradeable. This is the only form pneuma takes while it is not inside a living thing.

Because absorption is where pneuma stops being effort and starts being currency, everyone — caster or not — feels their own mastery here first: a well-attuned fire warrior fills their pool at a vent faster than an unattuned one, before either of them ever spends a drop.

Casting

Casting a spell spends pure pneuma, shaped into the spell's flavor as it is spent (Law 3). There is only one path: draw on the pool of pure everyone carries, and pay whatever your mastery of that flavor makes the shaping cost. An unmastered flavor is not blocked, just expensive and weak; a mastered one is cheap and strong. This is symmetric with absorption — the same underlying mastery governs both directions of the boundary — but the two are trained together, since mastery is built only by spending, never by gathering (see the ledger, below).

Progression: the ledger

Progression is resource-bound, not time-bound. The rule:

Pneuma channeled through a cast becomes that spell's experience. A spell's accumulated experience is its mastery. Your attunement to an element is the sum of mastery across that element's spells.

Consequences, all deliberate:

• Spending is progressing. There is no tension between using pneuma and growing; hoarding is never correct. Absorbing pneuma into your pool, on its own, grants nothing — only pneuma actually spent through a cast or an exertion builds mastery (Law 3).
• However you play is how you align. Attunement is derived from what you actually cast, not chosen from a menu.
• Attunement cannot be bought. Pneuma held grants nothing; only pneuma channeled counts. A rich buyer skips the gathering half, never the casting half — two gates, one for sale. Cast throughput (cast times, cooldowns) is therefore the progression pacing lever.
• Practice casting counts. A cast need not accomplish anything to leave residue — channeling fire into the air is legitimate practice. The pneuma cost makes it self-limiting.
• Grinding a cheap spell is self-limiting by construction: it burns real gathered resources slowly.

What attunement does: it makes your spells in that element stronger and cheaper, and grants passive effects. It does not unlock spells — individual spells are learned from masters, spellbook drops, and quest rewards, then deepened by use.

The warrior

The non-caster is not outside the system; they are its internal practitioner. Elementalists channel external, typed pneuma drawn from the world; a warrior cultivates the pure pneuma of their own body through exertion. Physical effort invests pure pneuma into weapon mastery, which sums into pure attunement — the same ledger (Law 3 treats "a cast" and "an exertion" identically), the opposite direction of flow.

Trade

• Typed pneuma — sites, drops, crystals — is the primary market good: freely gatherable and tradeable, and the raw material for both absorption and annihilation.
• Pure pneuma cannot be gathered from the world directly. It only exists refined — by annihilation of an opposed pair (a craft anyone can perform, always lossy) — or generated by a person's own effort (self-regeneration, deliberate exercise). Refined pure is a legitimate market good like anything else; trade sells fuel, never power, since the same handful of pneuma does more in a more deeply attuned pair of hands.

Open questions

• What does deep pure attunement concretely grant the warrior beyond weapon mastery? Likely tied to how elemental imbuing works, which is proposed but not yet designed.
• Should warriors and other non-casters reach elemental effects through imbued gear (weapons, armor)? Proposed, not yet designed — deliberately deferred until the base pneuma system above is settled.
• Is there a "death" or corrupting force opposed to pneuma? Largely rejected as a new substance in favor of death being a violation of Law 1's annihilation (destruction with no pure residue) and undead being beings whose Law 2 self-generation has failed — but this is explicitly deferred until the base system above is fully settled.
• Ambient dynamics: should weather and time shift local pneuma abundance (storms surging air)?
• Concrete numbers everywhere: absorption and casting efficiency curves at each mastery level, self-regeneration rate, annihilation loss rate, condensation costs.
