Osira

Osira is the older sister of Opala and daughter of the adult Farah. She's a highly skilled mage who is out to rule Egypt, thinking little of her mother and sister. After failing to assassinate Opala, she was exiled and sold her soul to the Serpent God in order to gain her magical powers.

She's highly knowledgable about both the Hikari and Kurai artifacts and seems to have an interest in Devon, wanting to keep him close by, presumably as a slave or servant.
