The 26th Century.
Earth is on the brink of extinction due to atmospheric pollution, resource depletion, and endless wars.
The United Humanity Alliance, carrying hope on its shoulders, boarded interstellar exploration ships to search for new resources.
And on an unknown planet far from Earth, they detected a stable reaction from a new energy source. This was the beginning of humanity's misfortune.

Heading toward the source of the massive energy waves, we witnessed a colossal structure for the first time. No, it was too repulsive to be called a building; it felt as if it were alive and moving.
The crew, seized by fear, curiosity, and awe, began their research.
Foolishly, I named this planet 'Ark' and grew fond of it. I was under the illusion that a new hope to save humanity lay here, and affection began to sprout.
As a result of the investigation, traces of a civilization about 300 years old were discovered. We also learned that not only the building we used as a base but the entire planet itself was a breathing living organism.
This was something humanity was not yet ready to accept.
The crew members slowly began to go mad. They offered themselves to the ground, sent futile messages to Earth claiming they would invite all of humanity here, and even committed suicide in the name of martyrdom.
