In Year 372 of the Great Card Tide Era, a century after the “Rifts” tore through Blue Star’s crust, alien races poured in from beyond the rifts. Humanity’s entire arsenal of modern weapons became useless, and civilization teetered on the brink of annihilation. In their darkest hour, humans awakened their psychic power and unlocked the “Card Path System,” derived from the source of the rifts. By channeling psychic power through cards, they could summon battle beasts, cast spells, and construct defenses, gaining the power to fight the aliens. Humanity had entered the Card Path Era.
The rifts carved human territory into seven major cities and more than a hundred ruined border cities, all constantly threatened by alien slaughter and corruption. Card Path powerhouses were humanity’s only hope. Those who stood at the summit of the Card Path, wielded countless cards, and protected the human race were revered as “Card Lords.”
