After landing on Elpis, the Vault Hunters are helped by Janey Springs, a junk dealer, who guides them to the spaceport known as Concordia. Here, the Hunters, under Jack's orders, request help from Moxxi to find the jamming signal. After raiding a former Dahl station, they find out that the signal was put up by the Meriff, the person in charge of Concordia, as well as Jack's former underling. While this is happening, Zarpedon also activates Helios' weapon system, the Eye which fires powerful lasers on the surface of Elpis. The Meriff is later killed by Jack at his office due to a failed attempt to kill Jack from behind. With Concordia secured, Jack and Moxxi guide the Vault Hunters to the next step in retaking Helios. They then proceed to infiltrate a Lost Legion base, run by two Dahl officers, The Bosun and The Skipper, in search of an artificial intelligence, which Jack plans to use to build a robot army. After defeating Bosun, it is revealed that the Skipper, who renames herself Felicity, is the A.I. they were looking for. Next, the Vault Hunters travel to a robot production facility, where Jack enlists the help of a scientist named Gladstone to build his robot army. Gladstone suggests using his prototype robot, named the Constructor, which has the ability to construct an infinite amount of robots. At first, Felicity agrees to help them by becoming the A.I. for the Constructor, but upon witnessing the violence she has to go through,she begins to hesitate. After being forced into the Constructor bot, she takes control of it and battles the Vault Hunters. Felicity is defeated, and her personality is deleted from the Constructor bot.
