Major Derlin was an Alliance field officer assigned to the Rebel base on
Hoth at the time of the battle that drove the Rebels from that system. He was the one burdened with the task of breaking terrible news to
Princess Leia Organa. When her friends,
Han Solo and
Luke Skywalker, were stranded outside in a Hoth blizzard, Derlin had to inform her that the shield doors to
Echo Base must be closed for the night. A stoic Leia complied, putting the safety of the Alliance base over her personal concerns for her friends.
