Melfina

Melfina is a bio-android created by Professor Gwen Khan using ancient biotechnology found within the Grave of the Dragon ruins. Melfina's appearance is of a petite and slender young woman with shoulder length black hair and large brown eyes. While her physical age appears to be seventeen, her real age is that of only two. She has no recollection of her past or why she was created, which very often troubles her throughout the series.Despite being an artificial humanoid, Melfina possesses both free will and human emotions as well as the physical need for food and rest.she was created to navigate to the Galactic Leyline, and is the only one able to act as a medium to access its vast powers. Because of this, the pirates referred to her as the "Maiden of the Leyline". In the last episode, the part of her spirit which was created to be the Maiden of the Leyline departs from her and relocates with the Leyline itself, meaning that Melfina is no longer bound to the Leyline and her past, and is subsequently freed from a forced destiny.
