The engineering block was a four story concrete building that had probably been ugly even before the apocalypse. Now it had a crack running up its east face from ground to roof and the smell of something chemical coming from one of the broken windows on the second floor.

The fence gap was obvious. A section maybe three meters wide where something had come through in the night, bending the metal outward from the other side. The ground around it was torn up. Deep impressions in the earth, not footprints exactly, more like something had been dragged through repeatedly.

Four people were already there when Tobi and Festus arrived. Two of them he recognized from the Colonel’s command table. The other two were students, a man and a woman, both holding lengths of rebar pulled from somewhere, both trying very hard to look like they weren’t terrified.

And Musa. Who had apparently followed them across the campus without being invited.

Tobi looked at him.

"I told you I was trying to figure out where I fit," Musa said.

He didn’t have time to argue about it.

The tone came again.

Up close it was different. Less a sound and more a sensation, starting in the soles of the feet and moving upward, like standing next to speaker equipment with the bass turned past the point of reason. The fence shuddered along its length. Somewhere above them a window cracked.

Then the east wall came apart.

Not the gap. The actual wall, three meters to the left of the gap, concrete and brick and rebar, and something came through it the way a person walks through a bead curtain. Like the wall was an inconvenience rather than an obstacle.

Tobi’s brain tried to categorize it and failed.

Big. That was the first word. The second word was wrong. It was roughly cylindrical in shape, maybe four meters long, two meters in diameter, with a surface that was simultaneously smooth and covered in something that moved, small rapid rippling motions across its entire body. It had no obvious head. No obvious front or back. It oriented toward them regardless.

The tone was coming from it. From inside it. The whole body vibrating.

The two students with rebar took three steps backward and stopped when Tobi didn’t move.

He wasn’t standing still because he was brave. He was standing still because his mind was doing rapid calculations about available options and not finding good ones and standing still was at least not using up energy.

The creature moved.

It was slow. Much slower than the things from last night. But slow and large had their own mathematics and the mathematics here said that if it hit anyone it was over.

Festus moved left. Good instinct. Spreading out, making the creature choose a target.

"Musa," Tobi said quietly. "The dark thing you showed me. Can you make it bigger than a coin."

"I’ve never tried."

"Try now."

"If it doesn’t work—"

"Try now, Musa."

He heard Musa behind him, heard the specific quality of silence that meant someone was concentrating extremely hard, and he kept his eyes on the creature and kept moving laterally, mirroring Festus on the opposite side.

The creature stopped.

Its surface rippling intensified. The tone dropped lower, so low it stopped being a sound entirely and became just pressure, and Tobi’s vision blurred slightly at the edges and he blinked hard against it.

Then he understood something.

It wasn’t just sound. The vibration was doing something, pressure against every surface it touched, and the thing last night that had pushed at his mind was the same principle, just a different delivery. They were pressure weapons. Different scales. Same concept.

His system confirmed it half a second later.

[PRESSURE RESISTANCE — MINOR: ACTIVE]

[PARTIAL MITIGATION ONLY]

[RECOMMENDATION: AVOID PROLONGED EXPOSURE]

Partial mitigation. So it was helping. He just couldn’t feel it helping because the baseline was so much worse.

The creature oriented fully toward him. He’d been moving, he’d been the most active target, and whatever it used to locate things had settled on him.

It surged forward.

He went sideways and it missed him and hit the wall of the engineering block and the impact sent a shockwave through the ground that knocked both rebar students off their feet. Concrete dust rained down. The crack in the building’s face spread another meter upward.

It turned. Faster than the first pass.

Tobi was already running, not away, parallel to the fence line, keeping it moving and turning and not letting it build momentum in one direction. He could feel the pressure increasing the closer it got, his skull compressing around the edges of his thoughts.

"Musa," he called out.

"I’m trying—"

"Bigger than trying—"

"I said I’m trying."

Festus hit it from the side with the machete. The blade connected and the creature’s surface rippled violently at the impact point and Festus was thrown backward by the vibration alone, not a direct hit, just the shockwave coming off the contact. He hit the ground rolling and came up but he was slow getting to his feet.

The creature ignored him and kept after Tobi.

Which meant it had a priority system. Which meant it was thinking, at least at a basic level.

He filed that away and ran.

He made it to the fence line and went along it, one hand touching the metal briefly for orientation, and the vibration in the fence from the creature’s approach traveled up his arm and briefly made his vision white out completely. He stumbled. One knee hit the ground.

The creature was six meters away.

He looked up at it and for the first time since the night before he felt genuinely, cleanly afraid. Not the productive fear that sharpens things. The other kind.

Then the darkness hit it.

Not a coin-sized circle. A disc maybe a meter across, flat and absolute, edges blurring into the air around it, and it struck the creature’s surface and the rippling stopped. Not slowed. Stopped. A section of the creature’s body going completely inert, that part of it ceasing to vibrate, and the tone cut out like someone had hit mute.

The creature reared. That was the only word for it, one end of the cylindrical body lifting, the whole thing curling, the surface going into overdrive everywhere except where the darkness had hit.

The tone came back but broken, stuttering, wrong.

Tobi was on his feet.

He hit it twice with the machete, targeting the inert section where the darkness had landed, and on the second hit something gave way in a way he felt through the blade and the creature came down and went still. 𝙛𝓻𝒆𝒆𝒘𝙚𝓫𝙣𝙤𝒗𝙚𝓵.𝙘𝙤𝙢

Silence.

Actual silence, the tone completely absent, and in the silence the campus sounds came rushing back. Voices. Wind. Someone far away shouting instructions.

Tobi stood over the creature breathing hard.

He looked at the inert section. The surface there was different, duller, the small rippling motion gone. He crouched down and looked at it closely and the system was already running.

[DEVOUR AVAILABLE]

[WARNING: HIGH DENSITY BIOLOGICAL MATERIAL]

[ABSORPTION MAY CAUSE INSTABILITY]

[CONFIRM DEVOUR: YES / NO]

Instability.

He remembered what the Bible said. Pain. Hallucinations. Temporary loss of control. He was in the middle of a campus with four hundred survivors and a Colonel who didn’t fully trust him yet.

He looked at the creature.

He put his hand on the inert section.

Yes.

The absorption was nothing like last night. Last night had been passive, fluid soaking into skin gently. This was the opposite of gentle. It hit him like cold water, a full body sensation, starting at the hand and moving upward through the arm and into his chest and for approximately four seconds everything went bright and loud and wrong.

He heard himself make a sound he’d never made before.

Then it passed.

He was on one knee, hand still on the creature, and Musa was saying his name from somewhere to his left and Festus was next to him with a hand on his shoulder asking if he was alright.

"Fine," he said. His voice sounded strange. Lower. "I’m fine."

He stood up.

The system was processing something, not prompts just activity, something running deep in the background, and he could feel it the way you feel your heart beating if you concentrate on it. Usually background. Now present.

Sixty four out of a hundred.

He was more than halfway to his first real evolution.

Musa was staring at him. The dark disc was gone, absorbed back into his hand, and his face had the look of someone reassessing something quickly.

"You put your hand on it," Musa said.

"Yes."

"After it died."

"Yes."

"Why."

Tobi looked at him. "I told you. Still developing."

Musa looked at the creature. Back at Tobi. Something moved behind his eyes that was either suspicion or calculation or both, and Tobi noted it and didn’t address it.

Festus was looking at the hole in the wall. Three meters wide, ragged edged, opening onto the street beyond. Through it Tobi could see the road they’d come up this morning and further beyond that, past the smoke and the broken city, two new gates tearing open simultaneously.

Different colored light this time. Not red. Not white.

Black, with something gold moving inside it.

The Colonel’s voice came from behind them. He’d come at a run with six people and he stood now looking through the hole at the new gates, at the gold light moving inside the black, and for the first time since Tobi had met him the Colonel’s face showed something other than controlled competence.

"What color is that," one of the students said.

Nobody answered.

The system went quiet in a way that felt different from its normal quiet. Not processing. Not monitoring.

Waiting.

[DIVINE GATE DETECTED.]

[CLASS: UNKNOWN.]

[HOST RECOMMENDATION: DO NOT ENGAGE.]

Do not engage.

In eight hours of apocalypse that was the first time the system had told him not to fight something.

The gold light pulsed once inside the black gate like a heartbeat.

Then something looked out of it.

Not a creature. Not yet. Just attention, vast and directionless and then suddenly not directionless, suddenly oriented, and Tobi felt it land on him specifically the way you feel a searchlight find you in the dark.

He did not move.

He did not breathe.

Sixty four evolution points. Vibration resistance still integrating. One machete and a borrowed baton and a campus full of people behind him.

The gold light pulsed again.

And then, slowly, the gate began to open wider.
