A major tech corporation uncovered an ancient temporal rift linking to higher-dimensional space. In an effort to monopolize energy, the company kept this discovery secret from the public. Its unyielding exploitation ultimately caused the rift to spiral out of control, unleashing non-Earthly spiritual energy across the globe. Taking advantage of this chaos, the corporation hastened its global monopoly. Over time, an increasing number of heroes, who could forge contracts with deities via spiritual energy, banded together to resist the malevolent forces seeking to annihilate humanity.
