Final Sequence: Lord of the Abyss

In a world ravaged by a Cthulhu-like apocalypse, the surviving people cling to scattered islands under constant attack from horrors rising from the deep sea. Power over these lands belongs to the ruling forces who hoard the Sequence Seeds, the sources of godlike abilities. When villains massacre Glen's community and kill the people he loves, his rage drives him to swallow a Sequence Seed he had kept hidden, awakening the forbidden Sequence 0 power. His path now becomes one of brutal revenge and relentless rise.
