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.

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.

The elemental square

The elements follow the classical (Aristotelian) square of qualities: 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:

• Fire + Air (heat) → lightning / storm-fire
• Fire + Earth (dryness) → magma / forge-heat
• Water + Air (wetness) → mist / ice / tempest
• Water + Earth (cold) → mire / clay / the deep places

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 the refinement chain: pure is distilled by burning fire against water or air against earth.
• 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. Mastery of all four is honestly achievable — the ledger already prices it (four elements' worth of pneuma channeled through four repertoires); 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 — their own breath.

Carrying pneuma: pools and condensation

Pneuma's natural home is a living body. Its physical form exists to move it between bodies and vaults:

• Internal pools. Absorbed pneuma sits in bounded per-element pools (plus pure). Casting draws from these pools directly — a mage at a fire vent draws breath; there is no ammunition management in the moment of casting.
• Condensation. Because the pools are bounded, the craft of condensing pneuma into physical form — crystals, vials — exists to get it out of bodies and into banks and marketplaces. Condensed pneuma is inert until drawn back in. Storage, stockpiling, and all trade happen in condensed form.
• Deepening the breath. Pure pneuma can be worked inward to permanently expand one's internal capacity — consumed gradually through deliberate practice (the ledger rule applies: capacity grows from pure channeled, never pure merely held). This is the shared long-term track for every archetype, and capacity matters for every element's pool, not just pure.

So typed pneuma is spent outward (spells, attunement) and pure is turned inward (capacity, healing, the self).

Casting and transmutation

Casting an elemental spell consumes pneuma of that element from the caster's pool. There are two ways to keep the pool supplied:

• Absorb typed pneuma — at sites, from kills, or from condensed crystals. Anyone can do this, attuned or not. Harvested pneuma is always the efficient fuel.
• Transmute from pure. A caster attuned to an element can convert their own pure pneuma into that element on the fly. Transmutation is gated on attunement (the unattuned cannot do it at all) and is always lossy — deepening attunement makes it less wasteful, never free. It is an emergency reserve, not self-sufficiency; the deepest fire adept still tops up at the vent before a real fight.

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.
• 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, the opposite direction of flow. The warrior also deepens their breath like anyone else, on pure won by their own effort.

Trade

• Condensed typed pneuma is the market good — freely tradeable fuel. Trade sells fuel, never power: the same handful of fire pneuma does more in deeper-attuned hands, so the caster is the catalyst, not the consumable.
• Pure pneuma is not node-harvestable and not freely traded. It is made — refined by annihilation of opposed pairs (always lossy), or generated by one's own effort. Whether annihilation-refined pure may be sold (as fuel-grade, distinct from self-cultivated) is still open.

Open questions

• What does deep pure attunement concretely grant the warrior? The cosmology is settled; the payoff is not.
• May annihilation-refined pure be traded, or is all pure bind-on-refine?
• Ambient dynamics: should weather and time shift local pneuma abundance (storms surging air)?
• Concrete numbers everywhere: pool capacities, transmutation/annihilation loss rates, condensation costs.
