Estela Arbizu

Estela Arbizu is the darklord of Marina and a Ravenloft Siren. She was once a beautiful human woman, but grieving the loss of her father and husband, both sailors, to the sea, she began murdering sailors to deny the sea goddess Ny her claims over them. When Estela fell in love with one of them again, she decided to try to kill Ny herself. Estela called Ny forth with a summoning ritual and attempted to kill her using a harpoon covered in the blood of her mother. The harpoon did not fell her, and Ny, angered by how Estela's transgressions, cursed her to become a Ravenloft Siren.
