Story
In the year 2956, the sun stopped shining. An inexplicable phenomenon extinguished the planet’s primary source of life, plunging Earth into perpetual darkness.
Without light, humanity faced inevitable collapse: failed crops, destroyed ecosystems, and a climate that became uninhabitable. Wars over the last resources and desperation wiped out almost all forms of human life.
Dr. Ezra Cain, an elderly scientist, was the last one to resist. With time running out, he built the Ark of Light, a machine capable of reactivating the atmosphere through geothermal energy, giving Earth one final chance to live again.
