Warden

The Warden is a heavily modified Fallen Servitor that was used by Variks, the Loyal to monitor the Prison of Elders in Destiny. Its core machinery has been removed, leaving a hollow shell affixed with multiple devices and parts of unknown purpose. With its core gone, the Warden appears to lack the sentience of a standard Servitor. Variks speaks to Guardians through the Warden, informing them of the prisoners they are about to battle and directing them to the proper chamber of the prison. It later becomes hijacked and appears as the main boss of the Warden of Nothing Strike.

In the Destiny 2's Forsaken expansion, Variks disappears from the Prison of Elders following the prison break, and the Warden's AI had begun to malfunction due to codependency from it's master, and it's up to a Fireteam of Guardians to take it down.

Trivia

 * The Servitor core found in the Vestian Outpost may be the same one that was extracted from the Warden.
 * Although the Warden first appeared in the House of Wolves expansion, it did not have an official name until The Taken King's Festival of the Lost event, which included a mask bearing Warden's likeness.
