Saint Elimine was one of the Eight Legends who fought in The Scouring, wielding the light tome Aureola and the healing staff known as the Saint's Staff. Afterwards she founded the country Etruria and started the St. Elimine Church.
It's said that as soon as Elimine's work on Elibe was done, she ascended to Heaven from a famous tower located in Etrurian capital of Aquleia, which is now known as the Tower of the Saint and houses both her Aureola tome and her Saint's Staff.
She was apparently a beautiful, blonde haired woman, as depicted in her cameo when linking Rekka no Ken with the Mario Kart: Double Dash!! bonus disc for extra items in the former.
