Yuyan

NPC from the Avatar RPG I'm running.

Yuyan Ueda is the daughter of Fire Nation diplomats who were imprisoned by the Earth King for a crime they didn’t commit. No stranger to realpolitik, she was sent to the Earth Kingdom to infiltrate Chin the Conqueror's army. Authoritative and competitive, Yuyan possesses a keen military mind. Initially, she kept her distance from her new friends due to her complicity in Chin’s rise to power, though she eventually came clean about her role and began dating Takumi. She is searching for her missing sister Yumi, a fellow spy who disappeared in Ba Sing Se.
