Amnesiac, Believing I'm an Ordinary Person [Interstellar]

---Blurb---

"This is a magnificent age. This is a peaceful age."

Ten years ago, a technological genius burst onto the scene, bringing fresh ideas to the stagnant technological development of Star City, generation 35.

His appearance was as fleeting as a flower in bloom. He died young.

Ten years later, an ordinary wanderer mysteriously vanishes from a crime scene. An ordinary doctor inexplicably disappears while helping investigate the case. People begin dying one after another at a once-renowned, now-declining technology academy...

"They perished beneath the tolling bells and were forgotten beneath the tolling bells, until the first decade arrived. They were born to the bells of death."

When the alarm sounds again, they discover that the technological genius who "died" ten years ago has returned.

Note: My writing still needs work, and there are many unresolved plot threads. I haven't decided when I'll do a major revision.

Theme: A decade-old dream, a familiar face unchanged.
