Neviril is the Sibylla Aurea, and the Regina of Chor Tempest. She has a reputation for being the best Auriga in the entire Simoun fleet, and is the object of admiration of both the other sibyllae and the cadets aboard Arcus Prima. She is so revered that junior sibyllae are reprimanded for addressing her without an honorific even in her absence. She is the daughter of Halconf, the chief administrator of Simulacrum's government. She and Amuria were very close, and she is devastated by the loss of her beloved partner.
