A world turned dungeon, comrades who betrayed me, and 300 years later... Gathering a new party to return.
About
All characters are adults.
About 300 years ago, a blue flash struck the world, and the world was forcibly reorganized into a dungeon.
Monsters began to spawn naturally throughout the world.
At the same time, a mysterious structure was detected in the Pacific Ocean—a massive tower extending 250 floors underground.
Humanity called that tower "Axis."
One year later, a white flash covered the world again.
This time, humanity awakened abilities.
And the concept of mana began to be defined in reality for the first time.
Furthermore, classes from fantasy stories became a reality.
Humanity tried to conquer Axis, but no one dared to step forward.
Then, six humans volunteered, and humanity gave them the name "First Six Pioneers."
Ten years after the six Pioneers entered Axis...
When they reached the lowest floor, a being calling herself the Master of Axis appeared.
"Even if you conquer this place, nothing will change. Still, as a consolation, I'll grant your wishes."
Power. Authority. Their respective desires. The wishes were granted. And three of them turned their backs. Ark pushed Guest, the Knight, and one other comrade, driving them to the brink of death. At that moment, they discovered a warp leading outside. They barely managed to return alive. However, since that day, the six Pioneers neither aged nor died. 300 years have passed. The three who betrayed them rose to the top of the world. Guest picked up the sword again. So did the Knight. And the last comrade vanished without a trace. ㅤ
