Warlocks have long studied the Traveler, mastering some of its arcane energies. Its true purpose still remains a great mystery, but discovering truth has always driven you into the unknown. Now, our enemies are the only thing that stands between you and the lost wonders of our Golden Age.
Warlocks have long studied The Traveler, which gives rise to their ability to harness some of its powers. As the Warlocks advance through levels, their arcane powers grow stronger.
In appearance, Warlocks can be distinguished by their rounded helmets and long vestments. As with the other player classes, in addition to head, chest armor, gauntlets, and leg armor, they have a special fifth armor slot that is unique to their class and further helps to distinguish them from their brethren in arms: a bond (armband) worn on the upper-left arm.
During their GDC 2013 Panel, Bungie stated that the Warlock class is meant to be reminiscent of the "space wizard," citing as influences the Star Wars series' Jedi knights, The Lord of the Rings series' Gandalf, and The Matrix series' Morpheus. For outfit designs, attire worn by trench soldiers in World War I was a source of inspiration.
