Madison Li

Doctor Madison Li is a scientist working on portable fusion power and hydroponics experiments in Rivet City She is in the Commonwealth working for the Institute as the head of their advanced systems division

Capital Wasteland
Madison Li was a scientist who worked on Project Purity with James and Catherine, a project to turn the Jefferson Memorial into an advanced water purifier to cleanse the Tidal Basin of harmful contaminants all "at once." Li's team approached Horace Pinkerton's science staff in Rivet City to assist with the project, eventually taking over the Rivet City science lab and Pinkerton's seat on the city council. While small scale tests with Project Purity proved successful, large scale tests were fruitless. Following the birth of James' child and the death of Catherine, James retreated to Vault 101 to raise his child, with the project ultimately shutting down with the Brotherhood of Steel ceasing all involvement with the project due to lack of concrete results. Following the shut down, Li returned to the science lab and began work on portable fusion power and hydroponics research.

Around 20 years later, James returned from Vault 101 to retrieve a GECK and restart the project, with the help of Dr. Li. While initially against the notion, with the arrival of James' child, the Lone Wanderer, Li moved her and her science team back to Jefferson Memorial to begin work again, James: "I told you it would work, Madison, and now I can prove it."Madison Li: "James! You're back!" James: "And with good news. I was right about Braun and the G.E.C.K. If we can find one, we can adapt it to work with the purifiers." Madison Li: "I'd like to believe you, James. Really I would. This is all just so... So sudden." James: "Madison, I'm telling you this is real. I talked to Braun himself. He confirmed it. Don't you see? This is what we've been waiting for!" Madison Li: "I... I don't know, James. So many years have passed. Is it really still worth trying?" James: "How could it not be worth improving the lives of everyone in the Wasteland? What could be a more worthy endeavor?" Madison Li: "You haven't lost any of your passion, have you James." James: "''It's as important to me as ever, Madison. I know it's important to you too. Let's finish this together." Madison Li: "James, I... We don't have a G.E.C.K. I can get a small team together, but we'll need proof that it works before people believe us." James: "I know, I was thinking about that. The lab at the facility had some old pre-war computers that we scavenged. One of them might be useful." Madison Li: "From the last reports, there's no power at the facility. Even if one of those computers had a database, we couldn't access it." James: "That's why we're going to head over there right now and get things up and running as best we can." Madison Li: "You know if it were anyone else asking me to do this, I'd have them run right out of Rivet City." James: "And you know I wouldn't be here if I didn't think this would really work. It's time, Madison." Madison Li: "Damn you, James. When this is all over, you owe me a drink. I'll get the team together." James: "Thank you, Madison. It's good to be working with you again.''" (James and Madison Li's dialogue) though the Enclave soon arrived to take over all aspects of the project, killing James in the process. With the help of the Lone Wanderer, Li took refuge in the the Citadel with the Brotherhood of Steel. Li assisted Scribe Rothchild in fixing Liberty Prime's power issues, which was later employed as a weapon against the Enclave. With a GECK obtained and the Enclave soon defeated, Project Purity finally began large scale purification, removing all contaminants from the Tidal Basin and providing clean water to the entire Capital Wasteland.

With the ultimate success of the project, Li left the Capital Wasteland and travelled north to the Commonwealth to pursue work with the Institute and to remain off the Brotherhood's radar, saying other members thought she "knew too much."

Commonwealth
By 2287, Li was head of Advanced Systems at the Institute, a division that focuses on high-energy weapons, reactors, the molecular relay and synth development. She was friends with Brian Virgil, prior to his disappearance, which was covered up by Shaun. She also worked on a project to create a Synth version of Shaun as a child, with the help of Liam Binet.

Effects of player's actions

 * If the Lone Wanderer has killed Three Dog before completing the Galaxy News Radio quest, the player character will need to talk to Dr. Li to resume the plot.

Other interactions

 * If the Lone Wanderer passes a Speech check before going to Project Purity, Dr. Li rewards them with five stimpaks.
 * After escaping to the Citadel, Dr. Li will be unavailable for conversation as she asks the Lone Wanderer to leave her alone. Entering Vault 87 and starting Finding the Garden of Eden will make her available for conversation again.
