Moira Brown

Moira Brown is an eccentric inhabitant of Megaton, a town in Fallout 3, and the owner of the Craterside Supply store, also in Megaton. She wants the Vault 101 Dweller to help her research a guide to the wastelands that she is writing, doing tasks such as scout a nearby Super Duper Mart for food and medicine.

If the player character helps Mr. Burke detonate Megaton's nuclear bomb, Moira survives the blast, as she was outside of town researching for her guide. However, the massive exposure to radiation transforms her into a ghoul. If the player has been to the Underworld, she will take residence there. Otherwise she moves to Rivet City. She does not appear to know she's a ghoul at first, but even if the Vault 101 Dweller points it out, her sorrow is extremely short-lived as, typical for her personality, she optimistically realizes that she's always wanted to run some experiments on ghouls and can now use herself as a subject. Moira will still offer the quest The Wasteland Survival Guide after she becomes a ghoul.

Moira's personality is extremely cheerful at all times, often excessively so; she takes as much delight in talking about what she's doing as possible. She remains inappropriately cheerful in even the most serious of circumstances. She is also extremely gullible. Almost every time after completing a mission for her you have the option to make her believe something completely ridiculous. A perfect example is after finishing the mission from the third chapter of the book where you must retrieve archives from a library filled with Brother Hood of Steel Paladins and raiders. After returning with the archives, she asks you about the library's condition. A dialogue option will then appear that tells her that you forgot your library card so you had to find them on your own. She'll then believe that the library was untouched by the war and is still up and running.

One benefit of one of her sub-quests to complete the Survival Guide is a beneficial mutation that causes the player's limbs to regenerate when suffering from Advanced Radiation poisoning. This may in fact be a predecessor to a sort of ghoul mutation.

At multiple points of this quest line you can attempt to convince Moira that writing the guide is pointless and that she should center on more important things. The first chance is at the very beginning of the quest chain that works off your Speech skill. If you fail your next chance is after you have completed the first chapter of the guide, it does not seem Speech is brought into effect this time around, it just seems a "lucky guess" as to which reply option you choose while talking to her. If you do convince her to stop writing though, you will gain negative karma, and a perk called "Dream Crusher" which causes anyone attacking you to have 50% less chance of scoring a critical hit. It also causes Moira's mood to mellow out and her to focus on her store, thus giving the player a discount on all items she sells and increasing her ability to repair items up to 72%. Before, she is able to repair up to 52%.
