Maud Pie is an Earth mare, daughter of Igneous Pie and Cloudy Quartz, granddaughter of Grammy Pie, younger sister of Limestone Pie, and older sister of Pinkie and Marble Pie.
Maud has grey fur and flat, purple eyes, mane, and tail. She wears a blue-grey dress most of the time and generally has a blank expression.
Maud is very stoic, and while she's mostly actually very happy she never expresses much emotion. She also likes rocks (to eat, look at, sniff, identify, and keep as pets) but doesn't like candy unless it's made of rocks. She cares greatly about her friends but doesn't express that care emotionally. She also has a sense similar to the Pinkie Sense and her favourite colour is grey.
