Seoni was born to a group of nomadic people. When she was young, she manifested magical abilities that become somewhat uncontrollable and kept them a secret from her family. Once her grandmother found out, she insisted on tattooing Seoni with traditional runes that tell the stories of their people and also serve as a conduit to the magical power that flows through her, allowing Seoni to properly control her magic. Since then, Seoni has continued her nomadic ways, eventually setting out to become an adventurer and explore the world. Seoni is somewhat reserved, but a natural leader who is also an excellent planner.
