As Flame Marshal, Eline Roaille is the highest-ranked foreigner in the Immortal Flames, the Grand Company of Ul'dah, apart from the Flame General Raubahn. As the Bull chose his inner circle for their worth, and not their nation of origin, the Ishgardianlancer seemed a natural choice for her skill at arms, leadership qualities, and resilience. This was in spite of her less than savory past, having grown up as a lowborn in the Brume and made to do whatever it took to survive—including stealing, killing, and whoring herself. Having joined the Flames, however, she has since gained a reputation as something of a paragon for her service during and after the Seventh Umbral Calamity.
Roaille's skintones resemble a Duskwight Elezen, but her Ishgardian heritage more strongly suggests that she is ethnically a Wildwood Elezen.
