Lucentezza

Lucentezza (ルクエﾝテズザ, Rukuentezuza), also known as the Dragon of Brilliance (輝きの竜, Kagayaki no Ryū), is a Light Dragon, and the foster mother of Asteria llewyrch. During the Dragon Civil War, Lucentezza was known for both her power, and beauty on, and off of the battlefield.Years after the events of the war, Lucentezza managed to come across a homeless, and greatly malnourished young girl named Asteria. Lucentezza saved the girl from the harsh elements, fed her, and ultimately ended up becoming the child's surrogate mother. Along with fostering the young child, she also decided to teach the young girl Light Dragon Slayer Magic. Years later, once Asteria's training had concluded, the Light Dragon proceeded to use Compact Regression in order to transform herself into a human, so that she was able to continue looking over her daughter, as well as travel the world without any burden.
