Born ten years prior to the occupation of Dalmasca by the Garlean Empire, Sindri joined a series of failed rebellions alongside her parents who worked as gunsmiths and explosives experts supporting the efforts of the front lines. Unfortunately Sindri proved a far more capable active combatant than either of her parents and as she entered adulthood so too did she enter war. Years took their toll and, in the years following the Battle of Carteneau in Eorzea, Sindri's parents convinced her to pursue a mission they hoped had no hope of completion; to find Cid Garlond in Eorzea and recruit his brilliant mind in the effort to reverse engineer the tools of their oppressors and use the Empire's own warmachina against it.
Sindri spent over two years pursuing this mission before news reached her of her mother's death and she returned to Dalmasca in grief to be by her father's side and mourn together. As Dalmasca's hope dwindled in the years that followed Sindri and her father changed tactics and battlefields both, aiding the Bozjan Resistance in the hopes that success there would lead to a crumbling of Garlean infrastructure and chain of command that could lead to Dalmasca's own liberation.
The bloody success of the Bozjan Resistance and the breaking of the IVth legion saw Sindri's war over with, and the still-youthful Viera free to pursue goals beyond retribution and death. Enchanted by memories of Eorzea's splendor during her time in the realm Sindri has returned to see what else Aldenard has to offer, and what life she may now live.
