Scatter

Scatter learned the one-way arrow the day she spilled her whole winter store.

She'd spent all autumn gathering a neat, bunched-up pile of seeds — concentrated, tidy, hers. Then she knocked it, and the seeds scattered across the whole forest floor, every which way. And she sat down, sure that if she just waited, they'd somehow roll back into a pile.

Her grandfather, an old chipmunk with a knowing twinkle, found her waiting.

"They'll gather back... won't they?" young Scatter asked hopefully.

"Not on their own, little one — not ever," her grandfather said gently. "Scattered things don't un-scatter by themselves. That's the way of the world. But—" he held up a paw before she despaired "—that doesn't mean they're lost. You can gather them back. You just have to do the gathering — pick each one up, carry it, re-pile it. It costs you fresh energy, real work. The universe won't tidy up for free. But you can tidy it, if you're willing to spend to do it." He winked. "That's the whole secret. Things spread out for free. Gathering them back always costs. Life is mostly the good work of gathering back what the world keeps scattering."

Young Scatter got up and re-gathered her seeds, one by one — tired, but no longer despairing. She'd learned the arrow only points one way for free. You can push against it — you just have to pay.

She scampered to PowerForge at twelve, because a place that studied energy ought to know which way it drifts.

Volt, her mentor, met her at the gate. "Which way does energy go, left alone?"

Scatter set a hot stone in a bowl of cold water. Slowly, the stone cooled and the water warmed, until both were the same mild temperature. "It spread," she said. "The heat left the bunched-up hot stone and spread into the water, until everything was even." Then she waited. "And it never un-spreads. The water never gives its warmth back to make the stone hot again — not on its own. Energy left alone always spreads toward even, and even is where it stops." She tapped the bowl. "That one-way drift is why you can tell a movie is playing backward — because scattered things un-scattering is something that never really happens."

Volt felt the evenly-warm bowl. "You are appointed," he said.

In her workshop, Scatter showed the arrow everywhere. A drop of dye spreading (never un-spreading). A hot drink cooling to room temperature (never spontaneously re-heating). A tidy room drifting into mess over a week (never tidying itself). "It's all the same arrow," she said. "Concentrated, useful, bunched-up energy always drifts toward spread-out, even, hard-to-use energy. That's why a battery runs down, a fire burns out, a warm house goes cold when the heater's off." Then she gave the working rules: left alone, energy always spreads from bunched-up to spread-out — never the reverse, never for free; spread-out energy isn't destroyed (the total is still there, Keep's books still balance) but it's much harder to use — a mildly-warm ocean holds enormous energy that you can't easily do anything with; and you can push against the arrow — gather heat, tidy a room, re-charge a battery — but every single time, it costs you fresh, concentrated energy to do it. "A student asked why we can't just 'recycle' the waste heat from everything forever," Scatter grinned. "Because gathering spread-out heat back into useful energy always costs more than you get — the arrow charges a toll every time you push against it. You can fight the scatter. You can never fight it for free."
