Tomoe was born in the fishing village of Awazu, located in the northwestern coast of Digyu. A surprise raid by the western nomads left Tomoe an orphan, and the young girl found her way to the Imperial City, where her Gift was discovered. Attuned to the crystals before her eighth birthday, she quickly developed incredible swordsmanship and archery skills. Tomoe’s short stature, youthful appearance and polite demeanor while in public manages to hide the young woman's true identity: a lethal assassin who strikes fear in all enemies of Digyu.
