Pershing

Pershing was a Titan Guardian in the ill-fated Wilhelm-7 fireteam, alongside Agadir. They followed a Fallen Vandal into the Cosmodrome loot cave during the events recorded in Grasp of Avarice. In the in-game message bottles, Pershing shoots Agadir over loot, and Agadir later destroys Pershing's Ghost and kills him.
