In the year 2040 of the old calendar, the sky shattered.
Aurora-like rifts known as "Sequence Fissures" appeared across the globe, with inhuman whispers drifting from their depths. Over the decades that followed, tsunamis swallowed cities, sinkholes devoured plains, the polar ice caps melted, and the equator plunged into endless night. All of it came to be known as the "Echoing Tides." Then came an upheaval unlike anything in human history: some people began to awaken, gaining the powers of legendary gods.
The truth about the Sequences remains locked away behind layer upon layer of secrecy.
Some call them the "Ladder to Heaven," a path to godhood. Others call them a "curse," claiming that the awakened are merely vessels inhabited by the echoes of gods.
