Recruited as a henchwoman to a tyrannical country lord, Rossi proved spectacularly inept at carrying out evil schemes due to her habitual kindness and good nature. After accidentally causing the death of her employer during a botched public execution, Rossi was accepted as a Hero by the local populace; a title she found much more to her liking than henchwoman.
Sadly, gratitude isn't edible and the demise of her employer left her hungry, without work and without a home. Undeterred, she left the her small village and vowed to Tyr to live up to her new heroic title. She would roam the land righting wrongs, upholding justice, and hopefully pocket some loose change along the way. Holy vows aren't edible either.
