The year was 3127 when Elias finally succeeded in building a machine that could travel through time. Scientists had called it impossible, philosophers had called it dangerous, and everyone else had called him insane.
Elias didn't care.
His first destination was the distant future.
The machine hummed, lights flashed, and the world dissolved into a blur. When it stopped, he stepped out into a silent city of silver towers stretching beyond the horizon.
There were no crowds. No vehicles. No signs of life.
Then he saw a man sitting alone on a marble bench.
The stranger looked about thirty years old, with calm eyes that seemed older than the stars.
"Hello," Elias said. "What year is this?"
The man smiled faintly.
"I stopped counting after a million."
Elias laughed, assuming it was a joke.
The stranger didn't laugh back.
After hours of conversation, Elias learned the truth. The man's name was Adrian. Thousands of years earlier, a medical experiment had made him immortal. He could not age, could not fall ill, and could not die.
"I've watched continents move," Adrian said. "I've seen oceans disappear and return. Every friend I've ever made became dust."
Elias was fascinated.
"You've witnessed all of history! That's incredible."
Adrian looked toward the empty skyline.
"At first, yes."
Over the following weeks, Elias returned again and again. They became friends.
One day, Elias asked, "If you've lived forever, what's the most important thing you've learned?"
Adrian was silent for a long time.
Finally, he answered, "That life is precious because it ends."
Elias frowned.
"But everyone fears death."
"Of course," Adrian replied. "Yet death gives meaning to choices. You have limited days, so every moment matters. I have endless tomorrows. Nothing is urgent. Nothing is rare."
For the first time, Elias pitied the immortal.
Years passed for Elias, but centuries passed for Adrian between visits. Whenever Elias arrived, Adrian was still there, waiting.
Eventually, Elias grew old.
On his final journey, he stepped from the machine with silver hair and trembling hands.
Adrian looked exactly the same.
"I won't be able to visit again," Elias said.
"I know."
The two friends sat together beneath an artificial sky.
"You've traveled through time," Adrian said. "Tell me, what did you learn?"
Elias smiled.
"That no matter the century, people search for the same things—love, purpose, and someone to share life with."
A rare tear appeared in Adrian's eye.
When Elias returned to his own time, he died peacefully a few months later.
Millions of years afterward, Adrian still remembered him.
Empires, planets, and stars had vanished into history, but one memory remained untouched: a brief friendship with a man who had all of time to explore, yet only one lifetime to live.
