FFXIII OC: Suri Oerba Nia

Suri was a member of the Nia clan, a Clan responsible for teaching the children of Oerba,  she was a little older than Fang and Vanille when she learned the reason her family became teachers in Oerba was because they were branded as L'Cie by the Fal'cie in their village and forced to do so, so that eventually they would find the villagers who would be suited to fulfil the focus of Becoming Ragnarok.

Suri discovered that shortly after she branded Fang and Vanille were chosen for this focus, and the war of transgression began.  When this happened she was dubbed to have 'fulfilled her focus' and turned to crystal.

Hundreds of years later she was discovered by a camper in the Oerba region and woke up.
