Onrai was a female deity worshipped by the Seoularians, a race of Humans that once ruled an area of space around their homeworld of Seoul 5. She was a mother goddess, embodying fertility and generosity. Onrai was also believed to be the Mistress of the planet Coruscant, the fountainhead of Human civilization, which the Seoularians called "Notron." A statue was erected in the goddess' honor in the main city on Seoul 5, which hid entrance to the planet's control room.
