Two hundred and eighty years after the death of Anthurion Solis, the First Light who conquered the world, humanity lives in the shadow of his legacy. The great empire he once built had long collapsed, replaced by small kingdoms vying for power. However, one thing remained eternal: Lingua Solis, the single language he created, became the tongue of all mankind, as if previous history had never existed.

In a remote village, standing atop the ruins of an ancient Solis tower, a child was born without great renown. His life was simple, but fate led him to discover an ancient record—the diary of Anthurion Solis himself. Within those ancient pages lies a truth far different from the myth the world believes.

As he grew, the child was drawn down a path filled with choices: following the Light to build a new world, or destroying the legacy that had long constrained human freedom.
