Ilsa Chesterton-Liao (b. 2978), "Princess”, is the daughter Natalia Chesterton, the founder-owner of the Lancers, and Lama (Marquis) Wolfgang Liao (from a cadet branch of House Liao). 

Ilsa resembles her mother, but is "heavier", with clear Caucasian features, whereas Natalia is more slender and more Asiatic looking. The eyes and the dark hair are the same though. She’s something of a wild child, a late bloomer that’s trying to find her place in a world where her mother takes a lot of space. She’s estranged from her father, whom she blames for her parent’s divorce.

She’s a highly trained, if somewhat inexperienced, mechwarrior and commander. Both her parents are nobles from old mechwarrior dynasties. The men used to call her “Princess” behind her back. She’d rather have a cool, epic callsign, but unfortunately you don’t get to decide that for yourself. The callsign stuck, and now it's second nature and hardly derogatory anymore. The Lancers love their Princess (way more han they'll ever love "the scary bitch") and would do anything to keep her safe.

She has the rank of Major and technically commands the 3rd battalion from her Battlemaster. She's currently taken a leave of absence (from her mother mostly) and resides in London, Terra.
