Even Mavis herself doesn't know that she was once a knight respected by thousands of people...
Mavis, an amnesiac antique with only 5 colors in his field of vision, harasses the wild wolfdog Perry on a daily basis:
Mavis: "Be my mount, I will be the knight, and you will be the horse."
Paley: "No." (Get used to it)
…
Intention: I will work hard.
