Beru Whitesun Lars is a human female moisture farmer on Tatooine, wife of Owen Lars and the woman who raised Luke Skywalker. The StarWars.com Databank describes her as "content to marry Owen Lars and lead the tough life of a moisture farmer" and as "fiercely protective of the child." She was introduced in Star Wars: Episode IV A New Hope (1977), played by Shelagh Fraser, and by Bonnie Piesse in the prequels and the Obi-Wan Kenobi series.
The counterweight
Where Owen refuses, Beru argues. Their scenes together are the closest the original trilogy gets to a domestic negotiation, and she is consistently the one advocating that the boy be allowed to leave — which makes the pair of them a genuine parental unit rather than a plot obstacle with two heads.
Nineteen years of the same decision
Recent canon material, particularly the Obi-Wan Kenobi series, has been interested in what it costs to raise a hidden child on a lawless world with a Jedi watching from a cave. Beru's steadiness across that period is not passive; it is the whole reason Luke arrives in A New Hope as a functioning, hopeful person rather than a damaged one.
Where to read her
The 1976 novelisation and the Attack of the Clones novelisation both give the homestead more air than the films.
