Sugar is sweet. Sugar is pretty. Sugar is a mouse.
Eek! A mouse!
Mice are the bane of every city as they live in the cracks and hovels and steal any food they can. You can try to poison them but they tend to be immune. As if they did not have short enough natural lives, they rarely get to live out their years because to normal humans mice are considered less than worthless.
Sugar dreams of a better life. She is doing everything she can to try to get past the stigma of being a mouse.
