Shurelia was the daughter of Eleno, and was very loved by her father. However, while Eleno was still working as part of the staff for the development of Ar tonelico, Shurelia was killed by a failure in the security systems of the Tower. This prompted Eleno to abandon all his projects, and stop working for a long time, until he was assigned the job of working in the creation of the Wings of Horus. Supposedly, the Reyvateil Origin Eoria is the splitting image of her, which is why Eleno gave her the name that everyone calls her now.
