Danbit Brun was a lieutenant in the Galactic Empire. As a male human, he worked on the Shield Gate above the planet Scarif as a shield relay systems operator. Brun's responsibility was to meticulously observe field dynamics in order to stop hazardous accumulations caused by stellar wind aurorae. He died in 1 BBY when debris from the Persecutor and the [Intimidator], a pair of Star Destroyers that were obliterated during the Battle of Scarif, collided with the gate, resulting in its destruction. Brun had gray hair and light skin. He was dressed in a black Imperial technician's uniform, complete with a cap.
The first appearance of Danbit Brun was in the film Rogue One: A Star Wars Story, which premiered in North America on December 15, 2016. While the movie did not identify him, his name was revealed in the reference book Star Wars: Rogue One: The Ultimate Visual Guide, authored by Pablo Hidalgo, which was published the day after the film.
