In the small, secluded region of Tamos-Kez, two High Demons spearhead a catastrophic assault on the lone village of Palios. The attack awakens long-repressed rage and guilt within the sole survivor of the settlement, an orphaned sorcerer named Icaro Swiftblade. Vowing revenge for the loss of his family and his village, Icaro sets out to seek reprisal, unknowingly altering his life-and his destiny.

Soon after banding with a traveling group of friends he truly calls family, Icaro learns of the surfacing of a mysterious relic from the Ancients' Era. He embarks on a journey to find the relic in hopes of using it to aid his revenge, but he soon faces trials and tribulations he never imagined possible.

Caught amidst striking revelations and deceptions, Icaro faces the burdensome task of confronting his troubled past and discovering the truths linking him to-and trapping him in-a resurging war between heaven and hell.
