Eschaton
After Judgment, Memory Becomes the Last Frontier.
In the aftermath of the Universal Judgment, humanity lives on distant planets, immortal and free from suffering—at least in appearance. But when Epigar, a heroic guardian, is annihilated by a forbidden weapon that erases not only the body but the soul itself, a terrifying truth surfaces: death has returned.
Cardian, a resurrected being without memory of his mortal life, is thrown into a galactic war between the authoritarian Guardians of Divine Order and the Reminiscent rebels, who fight for the right to remember their lost families. As Cardian journeys through duels, visions, and love—especially for the mysterious Onira and a forbidden child—his forgotten past begins to awaken, revealing a staggering secret: he was once a woman, Samsara, a revolutionary fighter whose essence may hold the key to salvation or destruction.
Blending epic science fiction with spiritual allegory, Eschaton is a metaphysical space odyssey that echoes the theological depth of The Divine Comedy, the philosophical provocations of The Matrix and Blade Runner, and the messianic undertones of Dune. At its core is a powerful question: what makes us truly human—eternal life, or the memory of love?
