Dungeon Under My House

Dungeon Under My House,

A young man discovers a secret going against common sense of this world—a fantasy-like dungeon—and takes control of it. Wasting no time, he brings his closest friends into the secret.
But was that a right decision? Even if the young man is determined to keep it a secret from the world, every person is different. Each has their own ideals and goals.
How long before the secret leaks out? What will happen to the world once it does? Or will everything be kept under wraps forever?
