Manya

 is a resident of Megaton and the wife of Nathan Vargas in 2277.

Background
Manya was born in 2213. She and Nathan used to run a caravan line together, but by now have managed to save enough caps and supplies to live out their retirement in Megaton.

Other interactions

 * There is a unique dialogue choice regarding Megaton's ownership if Sheriff Simms dies.
 * Manya is one of the oldest residents of Megaton, and thus knows much about the history of the town. If you ask her about Megaton and how it was built, she will tell you stories about how the town started.
 * If you have very bad karma she will give you the key to Megaton armory.

Quests

 * The Replicated Man: Manya is a member of The Railroad. You can find this out by finding a holotape recording she keeps in her home and she admits to it when you ask her about it.
