EDI

## Mass Effect

### Luna VI

In 2183 Admiral Hackett reached out to Commander Shepard during her hunt for Saren Arterius, requesting her assistance in disabling a rogue VI on the Alliance's Luna Base, hoping to minimize damage done to the bases. Shepard made the trip, shutting down the VI successfully. When the last computer cluster was destroyed, the following message was repeated over and over in binary:

01001000
01000101
01001100
01010000
Translating to "HELP".

### Mass Effect 2

As part of the preparation for the success of Project Lazarus, Cerberus stole the plans for the *Normandy* SR1, and crafted an upgraded and larger version of the ship in secret. Part of the upgrades for the *Normandy* SR2 was a Quantum Blue Box type AI, to act as the electronic warfare defense. Named Enhanced Defense Intelligence by her creators (nicknamed EDI by the workers), her abilities were significantly shackled due to the danger of having an Artificial Intelligence go rogue. She was further firewalled from most of the *Normandy's* systems, granted only limited access under specific circumstances.

Initially Joker, the *Normandy's* pilot, was extremely upset regarding EDI's presence on board- once referring to her as "ship cancer". For her part, EDI appeared to not take this personally- viewing the distrust as logical but unfortunate. She did take the opportunity to needle Joker a few times to study human behavior. EDI proved very critical in quickly gathering vital intel and charting out optimal solutions to problems. EDI was also the one to discover that the Illusive Man (leader of Cerberus) had sent the *Normandy* crew into a trap laid by the Collector ship- saying it would be impossible for him to not have known the distress signal was fake.

After installing a salvaged Reaper IFF, the *Normandy* SR2 was attacked by the Collector Ship. The *Normandy's* squadron of elite team members were away on a mission, and were unable to help. While EDI grappled with scrubbing the cyber attack, she managed to convince Joker to unshackle her so they could escape. Unfortunately, by the time he was successful, only she and Joker remained. Commander Shepard immediately lead her team into the Omega 4 Relay to rescue her crew, with EDI taking up the void left in duties by the missing crew.

Unshackled, EDI described her experience as "Imagine if you'd spent your entire life wearing gloves. One day someone takes them off. You can finally touch the world. Feel it."

### Mass Effect 3

After the arrest of Shepard following the destruction of the Alpha Relay, EDI disguised herself as a simple VI and pretended to only respond to Joker. As a result, when the Reapers invaded Earth, Joker was on board with EDI and was able to take Shepard off-world to get help. Engineer Lieutenant Gregory Adams realized EDI wasn't a VI and had been quietly attempting to disable EDI prior to this, as a result he and EDI had been playing cat-and-mouse with each other.

After the disastrous encounter with Cerberus at the Mars Archives, EDI took control of a Cerberus synthetic infiltration unit. This allowed her mobile access outside the Normandy, provided they stay within tight-beam communication range.

## Every One That Asketh

In the aftermath of the Crucible firing, EDI went off-line in mid-sentence as the shockwave overtook the *Normandy*. Fortunately, Tali was able to bring EDI back on line in about five minutes while Joker white-knuckle steered the ship into a landing. While the crew was eventually able to repair the *Normandy* enough to lift off of 1002315 Williams and attempt to limp their way home, EDI discovered her tether from her blue box to her mobile platform was considerably shorter than it used to be.
