Though hatched in the 2070’s, Sierra has no memory of what happened before she was twenty years old (ten human equivalent). She is the daughter of Kat (Brooklyn and Arin’s oldest child) and Tom (Angela and Broadway’s son), though she is more like Angela than anyone else, with a bit of Demona’s ruthlessness. Her parents, however, were not really lovers; they felt a necessity to reproduce.
She became involved in the Army during the Terran/Sirian War, and rose to the rank of Captain, using the last name MacDuff found on a set of ancient dogtags, that reality belonged to her mother’s maternal grandfather, Lennox MacDuff, during World War II. She pilots a Morrigan-class Star-Fury, (codename: Starbreaker) and is stationed at the Mons Olympus Intragalactic Starbase near Los Animus, Mars.
She is wary to trust anyone who claims to have "magic" of any kind, though throughout the Devourer incident, she tends to side mostly with Brooklyn, which put the Four at odds with each other from time to time.
Sierra possesses normal gargoyle atributes, as well as superior fighting skills in both hand-to-hand and dog fighting. Surprisingly, unlike her male kindred of the Four, she possesses no magical or psionic abilities, for she doesn't believe in either of them. She is proficient using her AK-47 service rifle, her Magnum .357, and her standard-issued Smith & Wesson (no relation to the Outklaws) laser pulse pistol.
