Origin: Sandy, an Aquyran from ocean world Thalyssia, lost her protective father at nine during a predator attack. Raised in matriarchal society where girls lead and boys nurture, she excelled at survival training but found solitude in dark reef depths. Discovering heavy metal band Abyssal Echo as a teen, their raw sound matched her inner storm. By seventeen, she'd found her calling: forging music that embodied her people's oceanic strength.
