The Fallen Sea Queen Was Their God

Sea princess Isa hides her divine identity to share a crown with the Four Sea Kings for four centuries. When the Tide Saint returns with forged evidence, the kings betray Isa, steal her heart-bound Crystal Tear, and cast her into an abyss. Her loyal guard Norn dies trying to heal her, but the elixir twists her into a sea monster. Bound by the Sea God's chain, the wronged goddess rises from the abyss to reclaim her throne.
