Speed

Base: MOMENTUM

Physics: Kinetic energy. Increasing the velocity of the body itself — not just locomotion but reaction speed, processing speed, the entire kinetic envelope of a living system.
Signature: The displacement. Not the motion itself — you often don't see that. The air that moves after they do. The papers that flutter. The dust that lifts. The sense that something just happened in the space you're looking at and your eyes were not fast enough to be part of it.

F-rank. Faster than makes sense. Not inhuman — an F-rank Speed user won't outrun a horse at full gallop — but in burst, for a few seconds, they move with a quickness that makes the eye lose them and find them again one step later than expected. The tell is the head: they turn to look at things before the things happen. A ball thrown across a training yard and the Speed user's head is already tracking the landing point while the ball is still rising. Reactions happen in the wrong order — they flinch before the noise, step before the floor shifts, catch something falling before anyone else has registered it leaving the shelf. The air signature is nothing at F-rank — a faint stirring, the kind of draft that could be an open window. The user's own experience is the more interesting tell: they describe the world as slightly slow, the way a conversation feels slow to someone who has already worked out what the other person is going to say. Their heartrate during burst is elevated for minutes after, the cardiovascular cost of the body moving faster than its own cooling system can manage.

E-rank. The blur begins. An E-rank Speed user in burst is visible but indistinct — the outline smears, the limbs trail afterimages that are not magic but simple retinal persistence, the eye holding the last position while the body has already moved to the next. Fast enough that sparring partners begin aiming for where the Speed user will be rather than where they are, and fast enough that the prediction is often wrong. Air displacement becomes audible: a sharp fft at the moment of acceleration, the sound of a body punching through air that wasn't expecting to be punched through. Their training shoes wear unevenly — the balls of the feet ground down, the heels pristine, because an E-rank Speed user has already shifted to a movement pattern that keeps weight forward, always forward, always ready to go. The smell of heated rubber from training-yard floors after sprint drills. The specific friction-burn on the forearm from grabbing a wall to stop, because the body learned to go before it learned to stop.

D-rank. Transition from fast to not there. A D-rank Speed user in burst crosses a room and the room notices — papers lift from desks in the slipstream, candle flames bend and gutter, dust lifts in a line tracing the path just taken. Fast enough that the sound of movement arrives after the motion is complete — you hear the fft and the Speed user is already standing still at the new position, and your brain has to reconcile the sound (they were there) with the sight (they are here). Sparring at D-rank becomes a problem of input: the partner can't track fast enough, so they fight by prediction and sound, and the Speed user exploits both. The body at D-rank runs hot — not Fire-hot, not mark-related heat, simple thermodynamic waste heat from a biological system operating at speeds the body's cooling was not designed for. They flush red during sustained burst. Sweat comes fast and heavy. The heartrate spikes to ranges that would alarm a physician.

C-rank. The sonic threshold. A C-rank Speed user at full burst moves fast enough that air compression becomes a factor — not a true sonic boom, not yet, but a pressure wave ahead of the body that shoves dust and loose debris outward in a cone, and the sound of their passage has shifted from fft to a sharp crack, the whip-snap of air closing behind them. They cross a training yard and the yard has a visible line — a dust trail, a scuff mark, a brief ribbon of disturbed air — tracing where they were a half-second ago. In combat, they are not invisible but unparseable: the eye tracks a smear of motion, hears the crack, sees the consequence without being able to reconstruct the action that caused it. Other Speed users at lower ranks can track them, which is why Speed-on-Speed fights are the only ones where the audience sees what's happening in real time. The user's body at C-rank has adapted: the cardiovascular system runs hotter, the cooling is better, the sustained burst window has extended from seconds to minutes. But the cost shows in the joints — knees, ankles, hips — the repeated high-speed direction changes grinding cartilage faster than even a ranked body regenerates. A C-rank Speed user who has been at it for years has a particular careful quality in how they walk at normal pace, the knees carrying memory of speeds the walk does not reflect.

B-rank. Hard to track visually. A B-rank Speed user at full burst is a displacement event — you see the departure (a crack of compressed air, a burst of dust from the launch point) and the arrival (a crack of deceleration, a burst of dust at the landing) and between them, nothing. The eye cannot follow. The brain fills the gap with a smear, a suggestion of motion, but the information was never received. What the bystander tracks instead: the slipstream — a gust of wind that hits a half-second after, strong enough to flatten hair and rattle shutters. The dual sonic report — one at departure, one at arrival, paired cracks of a body breaking and re-entering human-speed airspace. The debris trail — a line of lifted dust, moved pebbles, scuffed surfaces tracing a path the eye couldn't follow but the ground recorded. In repose, a B-rank Speed user seems normal until you notice the eyes. They track things you can't see — insects at the edge of vision, dust motes in a shaft of light, the specific vibration of a bowstring being drawn in a crowd. Their attention is faster than their body now, which means they spend most of their lives watching the world happen in a tempo they've outgrown.

A-rank. Invisible in sustained motion. An A-rank Speed user at full burst is not visible. Not blurred, not smeared — absent. The body moves between positions faster than light reflected from its surface can reach the observer's retina in a coherent image. What remains: sound (a continuous crack-crack-crack of air being broken and resealed, a whip snapped at a rhythm too fast to count), wind (the slipstream at this speed is a weapon — papers become edges, gravel becomes shot, the air itself becomes a wall), and consequence (targets struck, positions occupied and abandoned, a fight over before the audience registers it has begun). Other marks destabilize in their wake: candles extinguish, a Fire user's flame flattens and tears, dust patterns dissolve. Standing near an A-rank Speed user who is not fighting is standing near absolute readiness — the coiled attention, the eyes that have already mapped every exit, every threat, every trajectory in the room, and are now waiting for the world to present something worth moving for.

S-rank. Faster than nervous systems can process. An S-rank Speed user at full commitment moves through a space and the people in that space do not know they have moved until after they have stopped. Not because the people are slow — because the human nervous system takes approximately 150 milliseconds from stimulus to comprehension, and an S-rank Speed user crosses a combat space in less. They act in the gap between the stimulus and the response. A sword is drawn and the Speed user has moved behind the swordsman, disarmed them, and returned to their original position before the swordsman's nervous system has finished telling him his hand is empty. The sound at S-rank is weather — sustained rolling thunder following the user like a personal storm system, the continuous creation and collapse of pressure waves as the body punches through atmosphere at speeds the atmosphere resists. The slipstream strips paint, breaks glass, flattens crops in a line. The thermal wake is visible — the air behind an S-rank Speed user in burst shimmers with friction heat, a corridor of warm disturbed air that takes seconds to dissipate. In repose, the paradox: perfect stillness. An S-rank Speed user at rest is the most still person in any room, because they have achieved a relationship with motion that makes stillness a choice rather than a default, and the quality of a chosen stillness is different from the stillness of someone who has nowhere to go.

SS-rank. Between moments. An SS Speed user moves through space so fast that the distinction from time-manipulation becomes academic to the observer. A blink, and they have crossed a city. The air between departure and arrival is a catastrophe — a corridor of superheated, compressed, displaced atmosphere that collapses inward with a thunderclap heard for kilometers. The ground along the path is scored — not footprints but friction burns, the surface heated by the speed of passage, a dotted line of darkened stone tracing where each foot touched down for an instant too brief to measure. They perceive the world in a tempo that makes everyone else statuary. A thrown punch from an A-rank is a slow event they can study, admire, walk around, and choose how to respond to before the fist has traveled an inch. The processing speed that accompanies the physical speed is the true weapon — not just fast movement but fast cognition, fast perception, fast decision-making, the entire system running at a clock speed that makes every engagement a foregone conclusion.

Population context. SS Speed practitioners in the founding era were not warriors. They were messengers. The founding houses valued SS Speed not for combat — at SS, combat is trivially won — but for moving information between fronts, between continents, in the time it took another house to draft a letter. The sealed archives record one who delivered a signed treaty from the Sundric Reaches to the Ironward Citadel in Carath — six weeks by ship — in under an hour. The signature on the paper was still wet when it arrived. The guild considers SS Speed extinct. The courier trails — corridors of scorched earth between ancient cities — are still visible from high ground, grass growing differently where the ground was heated two hundred years ago.

SSS-rank. The practitioner is velocity — the relationship between a body and the space it occupies, expressed as a variable the practitioner sets. Stillness is a speed they choose. In their presence, the concept of position becomes fluid — they are not at a location, they are in a location the way a river is in its banks, currently here, fundamentally in motion, the stillness an illusion produced by the observer's inability to perceive the movement. Every particle of air in range knows their passage. Every surface remembers contact. The atmosphere carries a permanent, low-level turbulence — a restlessness, a sense that the air has not been still in a very long time and has forgotten how. When they act, there is no sound. Sound requires the observer to be present in the same temporal moment as the event, and at SSS the event is finished before the pressure wave can form. What the observer perceives is: nothing, then everything — the world rearranged, the fight concluded, the work done, and a silence that is not silence but the absence of the sound that hasn't arrived yet. It arrives later. Sometimes much later. The thunder finds you minutes after the Speed user has stopped and poured themselves a cup of tea.

Population context. SSS Speed existed in the founding era. The sealed archives do not describe what they did. They describe what they left: paths. Permanent corridors of altered atmosphere between the great cities of the Pre-Compact world, where the air still moves slightly faster than it should, where dust never quite settles, where a dropped feather falls at an angle because the air in that corridor remembers a direction it was pushed in ten thousand years ago and has never fully forgotten.
