Trivia

 * The Gjallarhorn was designed and personally crafted by Feizel Crux as a gift to the Guardians who fought the Battle of the Twilight Gap. It was forged from the armor of the Guardians who fell in battle.
 * Bungie 3D modeller and Gjallahorn's designer, Mark Van Haitsma, added a wolf onto the weapon for each day he spent working on it. A total of 16 wolves thus far can be seen in in the various images of the weapon.
 * Knights and gladiators inspired the design of the Gjallarhorn.
 * The Gjallarhorn was used in the Destiny live action trailer Become Legend.
 * During the E3 2013 gameplay demo, the Gjallarhorn was called the "Wolfpack." However, during a closed-doors session, Bungie revealed that this name was made up as a joke, similar to how the Patience and Time was nicknamed "Better Than Yours."
