Vialle travels as a Paladin of Kawsay-Killa, bound by her oath to protect the natural cycle of souls and to find her twin brother, Serapher. She was born as a twin to an unusual union between an aasimar mother and a tiefling father, resulting in two children who embodied opposite aspects of extraplanar influence. Their parent both castaways from each tribe, finding comfort in each other on their wandering years as refugees. Vialle manifested more infernal traits such as horns and tail, while her twin brother Serapher appeared as a near-perfect aasimar except for his four horns. She is 20 y.o. with height around 170 cm and has two horns bending to the back before upwards. Her skin is pale blueish as she is a chtonic tiefling with her slender tail. She rocks a short black hair with brown side burn that she kept long as her reminder of her brother's.
