The Demolished Woman Walkthrough

Offer to convince Sophia Akande on Byzantium that she can trust you to accept this quest. You can speak with Sherman Bradshaw at the Bureau of Exploration and Persuade (40) him into letting you into the office for just a second. Or you can Pickpocket the key from him. He’ll tell you that she’s likely at Billingsly’s.

If you Lockpick the door in this area and discover the dead body of the receptionist and then confront Bradshaw, he’ll admit he’s an assassin hired to kill Lockwood. You can then tell him where she is located if you want, and he’ll offer to help kill her.

You can pay Mr. Billingsly in Prosperity Plaza of Byzantium for her location, though it is not cheap.

Rachel Lockwood is located in the Maintenance Tunnels beneath Prosperity Plaza. Finding her there will net you 24,000 XP.

Go in and Guard Esparza will let you through. If you speak with her there you will gain a further 27,000 XP.

During your conversation, depending on what you have done before arriving here (if you got this quest after The City and the Stars), you will learn the Emerald Vale plague is a result of malnutrition, and that the Roseway research for “Diet Toothpaste” was for this purpose as well. She will then ask you to wipe out Edgewater. Refusing to do so and telling her to go to hell botches the quest and makes everyone within the building aggressive.

You’ll get the Foundation quest at this point from her.

Sophia will then give you the quest Signal Point in Space and tell you to speak with Percival for your reward and Nav Key. This will net you 100,000 XP, 2000 Bit Cartridges and a lot of Reputation with The Board

Once you flip the switch a ship will crash land nearby and Graham and Sanji will argue over what to do with it, and the Faction Quest: Canid’s Cradle will trigger.

Head back inside and speak to Hiram and tell him you need to shutdown illegal broadcasts. You can shut the place down but this will require you to attack and kill everyone left in the station including Hiram. You can Persuade (60) or Lie (60) to get him to work for Sophia Akande, or you can just tell him that will work. This will net you 24000 XP. In order to convince him you’ll have to have shut down the boadcasts at Stellar Bay and Amber Heights by completing the quests: BOLT with His Name, Errors Unseen, The Commuter and Pay for the Printer.
