The harbor of Tosali was a theater, and Aryavardhan was about to put on a play.
He stood on the end of the stone breakwater, the salty wind whipping his tunic. A small crowd had gathered—fishermen, idle sailors, and a few merchants curious about the "new signal device" the University had promised.
Among them, leaning casually against a piling and peeling a tangerine, was Girish.
The spy was good. He didn't push to the front. He stood where the sightlines were perfect but the attention was minimal.
Aryavardhan checked the device. It was one of the "Signal Tubes"—a short, thick iron pipe mounted on a wooden swivel.
Beside him stood Lohita, the blacksmith. He looked miserable.
"This is embarrassing," Lohita muttered, adjusting the angle of the tube. "I built a tiger, and you want it to meow."
"A tiger that meows lives longer than a tiger that roars," Aryavardhan whispered back. "Load it."
Lohita sighed and poured a scoop of powder into the muzzle.
It wasn't the good gray powder—the lethal mix of saltpeter, sulfur, and charcoal in the perfect 75:15:10 ratio.
It was "serpentine" powder—poorly mixed, with too much charcoal and damp sawdust added. It was designed to burn, not explode.
Lohita rammed a wad of wet straw on top of it. No stone. No iron shot.
"Ready!" Aryavardhan shouted to the crowd. "Behold the Voice of Kalinga! A signal to warn ships of storms from ten miles away!"
The crowd leaned in. Girish stopped chewing his tangerine.
Aryavardhan lit the fuse.
The flame hissed. It burned down into the touch-hole.
Pfffft.
There was no crack. No thunder.
Instead, a thick, lazy cloud of yellow-white smoke billowed out of the tube, accompanied by a sound that resembled a giant, wet cough.
Blooop.
The smoke drifted over the crowd, smelling of rotten eggs and wet dog.
A fisherman laughed. "That's the signal? It smells like my uncle after a feast!"
The crowd roared with laughter.
"It... it needs adjustment!" Aryavardhan shouted, feigning panic. "The sea air... the humidity..."
He signaled Lohita to try again.
Second attempt.
Fzzzt. Pop.
A small spark jumped out, followed by more smoke. It was pathetic. It was a failure.
Girish watched for a moment longer, a smirk playing on his lips. He tossed the tangerine peel into the water. He had seen enough.
Kalinga is rich, the spy's posture seemed to say. But they are amateurs.
He turned and walked away, disappearing into the market crowd.
Aryavardhan watched him go. He waited until the spy was truly gone.
"Pack it up," he told Lohita.
"They are laughing at us," Lohita growled, his face red.
"Let them laugh," Aryavardhan said, wiping soot from the rim of the tube. "Laughter makes people deaf."
That night, Aryavardhan rode out to the secluded cove north of the city.
This was the real laboratory.
No crowd. No spies. Just the sound of the surf and the moon reflecting off the black water.
Kavi was waiting there with the "good" jars.
"Did he buy it?" Kavi asked.
"He bought it wholesale," Aryavardhan said. "He thinks we are making expensive fireworks for distress signals."
"Good. Because this batch..." Kavi patted a ceramic jar. "This batch is angry."
Aryavardhan opened the jar.
Inside, the powder looked different. It wasn't a fine dust anymore. It was granular—small, hard kernels the size of millet seeds.
Corning.
Aryavardhan had introduced the process quietly. Instead of just mixing the dust (which separated during transport), they now wet the mixture with a little alcohol and urine, pressed it into cakes, and then broke it into grains.
Grain meant air gaps.
Air gaps meant faster fire propagation.
Faster fire meant explosion, not just burning.
"Load the test piece," Aryavardhan ordered.
They had set up a heavy timber target—a section of a decommissioned ship's hull, reinforced with iron bands—fifty paces down the beach.
Lohita loaded the same iron tube from the morning. But this time, he used the corned powder. And this time, he loaded a solid three-pound iron ball.
"Cover your ears," Aryavardhan warned.
He lit the fuse.
CRACK-BOOM.
The sound was fundamentally different. It wasn't a whoosh. It was a violent, tearing snap that slapped the chest. A tongue of orange flame, sharp and brief, stabbed into the night.
CRASH.
Fifty paces away, the ship's hull shattered.
The iron ball didn't just punch a hole; it smashed the timber into splinters. The force of the impact threw the heavy target backward into the sand.
Silence returned to the cove, ringing in their ears.
Lohita walked to the target. He ran his hand over the splintered wood.
"Gods," he whispered. "It didn't just break it. It erased it."
"That is the difference between burning and detonating," Aryavardhan said, walking up beside him.
"This is what we put on the ships?" Lohita asked.
"Yes. But not yet. We keep using the 'smoke signals' during the day. We let the spies see the failures. We let them write reports about Kalinga's 'silly toys'."
He looked at the iron ball, half-buried in the sand behind the target.
"And when the Mauryan fleet comes... we introduce them to the real thing."
The next morning, a report left Tosali via a pigeon, headed for the Mauryan trade post at the border.
To: Minister Radha Gupta
From: Watcher G
Subject: Kalinga Naval Developments
The rumors of 'Dragon's Breath' weapons are exaggerated. I witnessed a demonstration of their new 'Signal Tube'. It is a primitive distress flare using low-grade sulfur powder. It produces smoke and noise but has no projectile capability. It failed twice in calm weather.
Assessment: Kalinga is experimenting with pyrotechnics for signaling, likely due to their paranoia about pirates. It is a curiosity, not a threat. Their reliance on flashy, expensive failures is consistent with their character.
Recommendation: Ignore.
Aryavardhan sat in his office, reviewing the bridge inspection logs.
He didn't see the report, but he knew what it said.
He checked the mirror relay logs.
Station 3 (Northern Hill) reports clear visibility.
Station 4 (Coastal Watch) reports clear visibility.
The network was live.
He opened his notebook to Phase Three.
He wrote a single word: Integration.
The militia had the training.
The bridges had the holes.
The ships had the tubes.
The mirrors had the light.
Now, he had to teach them to work together.
He stood up and looked at the map of Kalinga on the wall.
It looked peaceful. Green forests. Blue rivers. Golden coast.
To anyone else, it looked like a paradise.
To Aryavardhan, it looked like a loaded mousetrap.
"Come on, Ashoka," he whispered to the empty room. "Take the cheese."
The trap was set. Now, all they needed was the mouse.
