Goddess of the Underworld

daughter of Zeus and the harvest-goddess Demeter, and
queen of the underworld. Homer describes her as the
formidable, venerable majestic queen of the shades, who
carries into effect the curses of men upon the souls of the dead. Persephone was abducted by Hades, the god-king of the underworld.

I thought that Goddess of the Underworld was more fitting for her than goddess of vegetation

I always thought of Persephone as a tragic figure in Greek mythology

so like her mother Demeter I'm going to add more elements so both are works in progress at the moment
