When a tsunami hits, mixed-blood orphan Selena dives into the deep sea and accidentally awakens the Sea God’s Crown, making the rightful heir to all seven seas. The elven elder of pure-blood faction intends to sacrifice her for her impure lineage, while elven prince Kaelos, dragon prince Noah, half-abyssal elder brother Leon and others become her guardians one after another. Selena uncovers her mixed elven and abyssal bloodline, reveals the thousand-year conspiracy of the old Sea God who oppressed all races with blood shackles, abolishes the pure-blood supremacy system, establishes an equal Seven-Seas Council for all clans, and finally sails her fleet to explore uncharted ocean territories.
