In the humble fishing village of Anvaris, Kael Taryon, a brash 19-year-old orphan, lives a quiet but unfulfilled life. Known for his quick temper and unpolished swordsmanship, Kael feels trapped, yearning for adventure beyond the village's shores. His only family is his adoptive sister, Lira, who constantly grounds him with her calm demeanor.

Kael's life changes forever when a mysterious stranger, Eryndor Vael, arrives in the village with tales of impending doom. Eryndor—a former Shardkeeper tasked with guarding the ancient fragments—reveals that Kael is the last descendant of the Starblood Line, the family chosen by Solunara to unite the shards and defeat the Voidborn.

Skeptical but intrigued, Kael dismisses Eryndor until his village is attacked by shadow creatures—Voidborn scouts. In the chaos, Kael accidentally awakens the Shard of Destiny, which burns a celestial sigil onto his arm. His fate is sealed.
