Rusalka

Rusalka, Demonlord of Emeraltides Queen of the Mermaids, Rusalka is revered as the first of her kind—mother of all Merfolk. Said to command the seas and curse the living into stone, she once protected her people in secret from the shadows of the Lost Sea of Dreams. But something changed. One by one, she began sealing her Merfolk within the veil... turning them to stone with her own hands. "Two-legged beasts have always betrayed us—in heart, by steel."
