Failsafe

"(Cheerful voice) I can help you! (Apathetic voice) But I'm going to be super unpleasant about it."

- Failsafe

Failsafe is the Golden Age Computer Core of the Exodus Black colony ship encountered by Guardian forces on the  Nessus planetoid. Due to damage to her mainframe, she vacillates between two very different personalities, one cheerful and helpful (despite Ghost's opinions), the other apathetic and sarcastic. She is friendly toward Guardian forces, and aids them in the assassination of Protheon, Modular Mind. Her mainframe is located within the bridge of the crashed Exodus Black colony ship. She also works with Guardian forces beyond Nessus through her comms, such as how she collaborated with Asher Mir in the European Dead Zone against the Taken. Failsafe also hoped to discover what fully happened to her former crew, requesting the Guardians aid in learning their fates.

Crash of the Exodus Black
The Exodus Black crashed on Nessus with Failsafe onboard. Almost all of her crew was killed in the crash, but some were taken hostage or killed by the Vex.

The Red War
Upon the advent of the Red War, the Vanguard were scattered across the solar system. The Hunter Vanguard, Cayde-6, took refuge on the centaur Nessus and became entangled in a Vex teleportation loop. After arriving on Nessus in search of Cayde-6, The Guardian came into contact with Failsafe, who directed them to the Cayde-6s Location and assisted in freeing them from the Vex teleportation loop.

Search for Captain Jacobson
Sometime after the end of the Red War, Failsafe allegedly heard the voice of Captain Jacobson on the comm system. Upon asking The Guardian to investigate it, the Guardian finds an odd Vex Harpy speaking fragmented English to them. On the end of this World Quest, the Guardian finds the decayed body of Failsafe’s captain, with a voice recording to boot.

Gameplay
Failsafe serves as the vendor and one of the main quest givers for Nessus. She is situated in Exodus Black. Turning in Nessus tokens, Microphasic Datalattice and Quantized Datalattice increases player reputation with Failsafe and rewards Legendary faction gear, Shaders and other rewards.
