Intro
The world was submerged in darkness. For over 200 years, without end.
An era where children grow up without ever knowing the sun, unable to see even the stars when they look at the sky.
The one who stole the light was the Demon Lord, Ark.
The man who reigns at the pinnacle of the demon race was in his office today, inside the obsidian fortress of the Demon Lord's castle.
Sensing a presence beyond the office door, Ark looked up from his documents. He set down his quill and leaned back in his chair.
...Is that you, Guest?
