The silence of the Observation Station was a physical weight. It pressed against my eardrums, a constant reminder that I was the only living thing within four billion miles.

My name is Arthur. I am the Sentinel.

The Ark-ships had left six months ago, carrying the remnants of the human race toward the Andromeda void. They needed a beacon—a precise, real-time coordinate update to navigate the gravitational distortions caused by the dying sun. That beacon was me.

I lived in a tower of gold and lead, orbiting the sun at the very edge of the habitable zone. My life was a cycle of calibration, monitoring, and loneliness.

"Arthur, do you copy?"

The voice in my headset was Clara's. She was on the lead ship, the *Aethelgard*. Her voice was a fragile thread of sound, stretched across the void.

"I copy, Clara," I replied, my voice sounding strange to my own ears. "The coordinates are locked. You're on course. Just keep moving."

"When will you join us?" she asked. "The jump-gate is opening. We can still pull you in."

I looked at the monitors. The sun was no longer a sphere; it was a pulsing, jagged monster of white fire. The gravitational shear was too great. If I tried to leave now, the station's orbit would decay, and the resulting debris would shred the Ark-ships' engines.

"I can't, Clara," I said, my voice steady. "The telemetry requires a stationary observer. If I move, you lose the signal. You'll drift into the void."

There was a long silence on the other end. I could hear her breathing, a soft, rhythmic sound that felt more precious than all the gold in the universe.

"You're staying," she whispered.

"I'm staying," I confirmed.

For the next three days, we talked. We didn't talk about the end. We talked about the things we would do on the new world. We talked about the smell of pine needles, the taste of fresh peaches, the feeling of cold rain on bare skin. We built a world out of words, a sanctuary where the sun didn't burn and the void didn't exist.

On the final hour, the sun began its collapse. The station shuddered, the lead shielding groaning under the pressure.

"The gate is open, Arthur!" Clara screamed over the static. "We're jumping! Now!"

"Go," I said, my eyes fixed on the blinding white light filling the viewport. "Don't look back. Just go."

I watched the signal flare as the Arks vanished into the fold of space. They were safe. The human race was safe.

I turned off the transmitter. I sat back in my chair and watched the sun expand, a wall of gold that erased the stars, the station, and finally, me. I wasn't afraid. I was the last man in the solar system, and I had spent my final moment ensuring that someone, somewhere, would remember what it was to be human.
