Hezen Protective
From Destiny 1 Wiki
The Hezen Protective is one of the Vex programming collectives. It is the secondary force found on Venus; not encountered as frequently as the Hezen Corrective, they are mainly found in the Citadel, the Endless Steps, The Nexus, and the Vault of Glass. The Protective's activities go beyond simple defensive measures, as they actively work towards completing a colossal project of unknown nature. The Hezen Protective can be identified by their brass bodies with white stripes.
