The night left fingerprints on the windows even through the blackout cloth. Kael woke to the small, obedient square of the LED panel and the smaller, less obedient square of fear under his ribs. He put the ledger on his knees and let the day grow a spine.
"We do not need to be brave," he said.
"We need to be correct," Mira answered.
Nox: "And tuned."
Renn, careful: "And on the dots."
[System: Day Plan] - Mission A: wire the Bell - Light link at A1 (reed switch - > Power Box Mk I) for silent visual alerts. - Mission B: unlock and use Traces & Reagents to run first tests on STAIRS - 2/BLUE - DUST. - Mission C: deploy Noise Pot decoy under the stairwell; practice lure - and - evade on human scouts. - Secondary: update safe - walk floor grammar; add 'wait squares' at choke points. - Reward: +1 PC for functional Bell - Light link, +2 PC for successful reagent analysis, +1 PC for decoy trial without contact.
PC available: 27.0.
Knowledge available: Bio/Chem T0 - > Traces & Reagents (cost: 2 PC).
"Today we teach the bell to blink," Kael said. "And we ask the blue to confess or at least stutter."
He purchased the node.
[System: Knowledge Acquired]
Traces & Reagents installed.
Effects: +field tests for pigments, proteins, oxidizers; +improvised indicator prep.
PC remaining: 25.0. - - - Bell that blinks
He scavenged a reed switch from a dead magnetic window sensor in a junk drawer that had survived three apartments and two breakups. He taped the reed to the inside frame, parallel to the door's edge, and fixed a small magnet to the knob string so that any motion would change the field and close the circuit.
He wired the reed through a resistor to the LED strip's control line on Power Box Mk I and soldered a tiny transistor tapped from a toy car to amplify the blink. He added a toggle so the system could be silenced without tearing tape in the dark. He labeled the toggle with a line and a circle because words near alarms can betray you when your mouth forgets shapes.
"Test," Kael said.
Mira turned the knob by a whisper. The paperclip bell clicked once. The LED panel blinked twice: a brief, polite star in the room.
Renn grinned despite sleeplessness. "That is beautiful," he said. "It is like a thought turning on and off."
Nox nodded. "Thoughts that blink mean we live."
[System: Craft]
Bell - Light link operational.
Effect: silent visual alert; +response speed in quiet hour.
+1 PC.
Kael wrote BLINK PROTOCOLS on a clean page and sketched the wiring like a map to a place he already loved. Rules beneath: - Blink = door touched. - Double blink = knob turned enough to move paperclip. - Solid = manual ON for work. - Never blink at windows. - Toggle to silence during hymns only if two humans awake.
He underlined the last rule twice. Humans lie. Rules do not. - - - Blue dust on a plate
Traces & Reagents arrived in his head with the plainness of recipes. He cleared a patch of table, boiled water, and laid out the jar labeled STAIRS - 2/BLUE - DUST, cotton swabs, scrap glass from a picture frame, a dribble of vinegar, a pinch of table salt, a dot of dish soap, and the bleach bottle. He explained every step to the room because teaching was how he made his hands honest.
"Control: dust in water on glass." He stirred a tiny smear with a drop. "Observation: particles settle slow, binder likely oily."
"Test one: soap micro - emulsion." He added a micro - drop. The dust dispersed better, leaving a faint turquoise tinge, then clumped again. Mira's nose wrinkled. "Smells like paint and pennies."
"Test two: bleach. Tiny. Watch for oxidation." He wicked the smallest breath of bleach into the mixture. The turquoise shifted toward green for a second, then paled, and a faint ammonia bite rose.
"Test three: vinegar." He added a drop at the edge. No fizzing. The color did not care.
"Test four: salt." He sprinkled a grain. No drama.
He drew conclusions with a pencil that did not lie: "Pigment likely phthalo or similar. Binder not purely water - based. Trace protein possible from the ammonia hint when oxidized. Could be contaminated by environment or intentional additive."
Mira watched his face. "So?"
"So it is paint," Kael said. "And also not just paint."
Nox grunted. "People paint with what they have. People also smear with what they are."
Renn said softly, "Bleach hurt where they touched me. Maybe they mix something that likes to be skin."
Kael nodded. "Procedures: if blue on skin - > soap and water first, then dilute bleach brief, then rinse, then barrier cream if we ever find some. If blue on wall - > leave it for now unless we need to erase grammar."
[System: Analysis]
Blue dust: pigment plus probable organic contaminant.
Action: treat with hygiene protocol; do not burn indoors; avoid inhalation.
+2 PC.
He labeled a small jar with a piece of tape: BLUE/CONTROL, and another: BLUE/BLEACH, and set them aside in a box that said DO NOT PLAY on a sticky note only he would obey. - - - Wait squares and floor grammar
Thread improved the path. Mira chalked small hollow squares at two choke points in the corridor where allies should stop and wait for visual confirmation before proceeding. She circled each once, then blew dust across them so the marks became a secret you had to want to see.
"Wait means live," she said. "Dots mean go. Squares mean still."
Renn practiced, moving from dot to square without looking down, watching only Mira's hand signs. Kael timed him and wrote: Scout latency improved. He considered being proud and then agreed to be a little proud.
[System: Path Update]
Safe - walk grammar expanded: dots = move, squares = wait.
Effect: +ally coordination in trap corridors. - - - Noise Pot and returning scouts
Under the stairwell, Kael set the Noise Pot: a tin can half - filled with pebbles, hung by a paracord run through pulleys to Anchor - 2. A tug would jostle the pebbles and create a sound far away from their bodies, like a ghost rehearsing.
At midafternoon, footsteps arrived: a trio moving with more caution than yesterday's thieves. Kael recognized the cadence of men who had learned a door can be a teacher. He put two fingers down: hold. He tugged the cord once, gentle.
The pot rattled under the stairs, harmless and suggestive. The scouts paused, then flowed that direction like water toward gravity. Mira gave the hand sign for ready. Nox smiled a private bar smile. Renn's breath went quiet.
They watched from the angle as the trio reached the stairwell mouth. The first man prodded the darkness with a broom handle like a superstition. The second held a knife low, eyes slit, scanning for lines at ankle height. The third stayed back, peering upward toward floors unknown.
"String people," the first muttered, almost respectful.
Kael tugged again, softer. The pot whispered. The men advanced half a step and then half a step more. They did not see RN - 4; it was behind them. They did not cross it; they had approached from the other side. Good. RN - 4 remained a friend for later.
"Do we... do we bite?" Renn breathed.
"We do not owe them teeth today," Kael said. "We owe ourselves a proof that the corridor can be empty on command." He tugged twice, cadence like an invitation. The men followed the sound into the stairwell, then stood listening to the building's long throat. After a minute, they retreated the way careful men retreat: backward, eyes on the dark, mouths bored. They left. No contact. No tally for blue.
Mira exhaled. "I like when the world obeys pulleys."
"So do I," Kael said.
[System: Decoy Trial]
Noise Pot effective. Threat diverted without contact.
+1 PC. - - - Blink tells a story
Near evening, the reed switch blinked twice without the paperclip click. Mira's head snapped up. "Light blink double. No click."
Kael pointed at the toggle: on. Nox rolled silent to the door. Peephole: empty hall. Then a shadow that did not cast itself right. He stared a second longer and saw it: a thread of blue paint brushed onto the knob string itself, so thin it was trying to be a rumor.
"Someone touched our string," he said softly.
Kael's jaw found a new angle. He cut the string free, coiling it like a dead snake, and installed a new length with the magnet taped under a tiny sleeve of black cloth. He moved the paperclip bell two centimeters. He wiped the knob with bleach and then with water and then with contempt.
Mira's mouth was very small. "They are trying to write us," she said.
"We are unwritable without our consent," Kael said. He wrote in the ledger: BLINK WITHOUT CLICK = tamper condition. He underlined it until the page felt the pressure.
[System: Security Update]
Tamper condition defined; hardware rotated; signature reduced. - - - Blue's outside sermon
After the tamper, they checked the alley again under the hymn, moving like obedient punctuation. On the wall beyond RN - 4, a new phrase had appeared in taller letters, painted over older tags: BRING LIGHT TO THE CRO W N. The O in CROWN was a circle with a dot. The spacing was wrong. The grammar was wrong. The need was loud.
Nox shook his head. "They are begging."
"Or baiting," Kael said.
Mira drew a tiny L - shaped mark near the ground, almost gone as she made it. "If someone bored follows, they will find a dot after the corner."
"Breadcrumb," Renn said softly, understanding the shape of an invitation that is not a trap.
They did not go around the corner. - - - Light discipline, refined
Back inside, Kael dimmed the panel with a small resistor he spliced in, so that it did less to the room and more to their eyes. He hung a folded cloth as a baffle and cut a narrow slit so the light made a stripe across the table and left corners in darkness. The world felt like a stage where they were both actors and audience, and that felt correct.
He added a rule to Light Discipline: blink test every hour; never ignore a double blink; rename blink patterns in words everyone can say under stress. They rehearsed: blink, double, solid, dead. They said the words until they felt like tools.
[System: Procedure]
Light Discipline v1.1 written. Effect: +response, - false comfort. - - - Moral math and small dissent
As they ate, Mira picked at her rice. "I want to draw a big word," she said suddenly, surprising herself. "I want to write NO on the wall over WE COUNT YOU. Not for them. For us."
Kael considered. "We do not participate," he said.
"I am tired of not participating," she said. "I want to tell the wall to shut up."
Nox chewed and watched the table like it might answer. Renn said, "Maybe the wall wins when we write. Maybe it wins when we do not. Maybe winning is the wrong word."
Kael looked at Mira and then at the crown and then at his hands. "We can draw a box around their sentence," he said at last. "Not over it. Around it. It will mean: contained. It will mean: we decide where it lives."
Mira's shoulders lowered. "I like that," she said. "I like boxes."
They stepped out on the hymn and drew a thin rectangle around WE COUNT YOU, with corners neat and corners square. They did not touch the words. They contained them. Then they left the hall to decide how it felt about that.
[System: Counter - mark]
Containment box drawn. Effect: morale + small (Thread). Blue response: unknown. - - - Quiet Court: the day that blinked
Kael read the audit by stripe - light. - Bell - Light link wired and tested; blink patterns defined. - Traces & Reagents unlocked; blue dust tested; procedures written for skin and wall. - Noise Pot trial successful; scouts diverted; no contact. - Path grammar updated: dots (go), squares (wait). - Tamper event detected: blue on string; hardware rotated; condition logged. - Blue outside escalates "BRING LIGHT TO THE CROWN"; ignored; breadcrumb placed. - Containment box drawn around WE COUNT YOU; morale adjusted. - Doctrine: repeated.
[System: Audit Complete]
+1 PC (blink link), +2 PC (reagent analysis), +1 PC (decoy success), +1 PC (discipline), +1 PC (doctrine).
Total PC: 30.0.
Advisory: With 30 PC, Tier - 1 nodes within reach (Engineering T1: Materials Fatigue, Energy T1: Battery Banks, Info T1: Signal Analysis). Caution: fatigue risk if purchased in sequence.
Kael did not buy. He wrote the options and left the boxes empty, like rooms ready but unlit.
He closed the ledger and set his palm on it. Ritual blinked in his head like the LED had taught it a trick.
"We do not need to be brave."
"We need to be correct," three voices answered, one of them newly certain, one of them happily heavy, one of them careful like thread.
The LED blinked once because Kael could not resist flipping the toggle. The room smiled in the small way rooms smile when they have learned how to warn without shouting.
Outside, the boxed sentence sat inside its new rectangle like a loud child in a chair. Down the hall, the pendulum rested with gravity behaving. In the alley, RN - 4 remembered a tug. The city sang its hymn because pipes are better at surviving than people. And the blue waited for replies it would not get, which is, sometimes, the best reply.
