Sarah has long blonde hair and blue eyes. She is simplistic, austere, and devoted to the ideals of the Brotherhood. However, she is not crazed or genocidal like most Chapters and is much more liberal, trying to help people as much as she can while adhering to the Brotherhood Code. She does not care much about Wastelanders though, and while she is a skilled and experienced fighter and solid companion she looks down upon the Wasteland. She is also focused on her mission, disregarding collateral.
