Moira Brown

 is the eccentric owner of Megaton's Craterside Supply in 2277.

Background
Moira was born in 2253 in the trading community of Canterbury Commons, but lives in Megaton in 2277.

Daily schedule
Moira is the owner of Craterside Supply. She spends the day sweeping and trading as well as conducting odd experiments. She opens the store at 8:00am and closes at 8:00pm. She lives at the store and thus never leaves. The only time she will leave is if Megaton is destroyed, in which case she is turned into a ghoul instead of being killed, and she will then make her way to Underworld and set up shop there. If The Wasteland Survival Guide is completed, she will instead stay near the entrance to the ruins, and only be able to repair, lacking an option to buy or sell items.

Moira's shop gets re-supplied on Sunday and Wednesday.

Quests

 * The Wasteland Survival Guide: Moira wants you to do some dangerous research for a book she is writing.
 * The Replicated Man: Moira is in possession of a Replicated Man holotape.

Effects of player actions

 * If you decide to blow up Megaton she will not die; instead she will be ghoulified. You will have to visit the Megaton Ruins to find her, whereupon she will claim she was 'out-of-town' during the detonation, and apparently unaware of her recent affliction. Depending on how you break the news to her, she will either fall into despair or remain positive. Eventually, she will leave for Rivet City and finally Underworld.
 * Convincing her that writing The Wasteland Survival Guide is a bad idea will result in a 30% discount on her wares and increase her repair skill to 54 (72% condition). You will also lose karma and get the Dream Crusher perk.
 * Giving her any other armor that lacks +5 repair will reduce her repair skill by 5 points, dropping the maximum condition she can repair to 69%. However giving her the workman's coveralls from Point Lookout will increase her repair to 59 allowing her to repair to 75% condition.

Appearances
appears in Fallout 3

Bugs

 * Occasionally, Moira will not move from the Megaton ruins after the town has been destroyed if you have completed the quest The Wasteland Survival Guide. She will stand in front of Megaton and can only repair.
 * After killing Moira . opening her Craterside Supplies container, and stealing an item, a voice clip of her saying "Hey, that's valuable junk!" will play, even though she's dead.
 * If you kill Moira and then decide to blow up Megaton, her body can be found outside of the Underworld entrance.

Behind the Scenes
Moira may have been named after a character from the film On the Beach (1959) IMDBwhich takes place in a post-nuclear Australia. Tim Cain mentions in a video interview that On the Beach was an inspiration for Fallout.
