Astralis is a world of six elemental kingdoms—Fire, Water, Earth, Wind, Lightning, and Light—once united by powerful Guardians who maintained balance. That peace was shattered centuries ago when war erupted between Fire and Water, ending in the fall of the original Guardians and leaving lasting distrust between kingdoms. In the present, the Guardians’ descendants begin to awaken their inherited powers, including Syouta, the volatile new Fire Guardian, and his sister Samira, the Water Guardian, whose bond is strained by secrets and responsibility. Alongside other heirs of the elements, they are forced into an uneasy unity as ancient tensions rise again. Unbeknownst to them, Lord Icarus—the forgotten Guardian of Death—manipulates events from the shadows, seeking to reignite the Everlasting War and reshape Astralis through chaos. As history begins to repeat itself, the new generation must decide whether to break the cycle of destruction or be consumed by it.
