Ellen Park, the Lone Wanderer

Thomas thinks for a moment. "There's a woman who goes by 'Yinzerella' living on the south side of town," he says. "She was a slave in the Pitt. Said the Brotherhood of Steel showed up with an army of robots behind them and started trading them for people- and letting the people go free. I don't know where she's from originally, but she survived the Long Eighty and made it here in one piece. That's about all I've got for you, though."
