Tendrando Arms, a company focused on defense, was established by Lando Calrissian alongside his spouse, Tendra Risant Calrissian. Its purpose was the creation of state-of-the-art battle droids during the conflict with the Yuuzhan Vong. Their initial offering, the formidable YVH 1 droid, met with considerable success. Subsequently, a less intimidating, but still lethal model known as Nanna was employed by Luke Skywalker to protect his son, Ben Skywalker, functioning as both a nanny and a bodyguard.
Following the end of the war, Tendrando Arms persisted in its role as a defense supplier for the Galactic Alliance.
