Chewbacca is celebrating Life Day alongside his honor family
A Wookiee honor family is a group encompassing a Wookiee's closest friends and trusted comrades. This bond, a special bond of friendship, unites a Wookiee with other Wookiees, and even individuals from different species.
Those who are part of honor families commit to sacrificing their own lives for one another. This protection is also extended to the honor families of each member.
The Wookiee, Chewbacca, regarded Han Solo, Princess Leia, Luke Skywalker, along with the droids R2-D2 and C-3PO, as members of his honor family.
