Once you secured a horde of marauders under your command, you set to dominating the wasteland. You took control of a pre-apocalypse hydroelectric dam and established your bandit kingdom. Some years of conquest later you've gained control of the region, and have recruited smart men to reactivate the dam.
With a stronghold now powered by electricity, you've set your sights on the future and decided you need heirs. To that end, you've recruited Amazing.
Amazing is one of your smartest smart men, plus she's a woman. You don't understand a lot of what she says, but she says she makes sense. She grew up in the wastes, scrounged the dead earth to survive each day, and never knew comfort. You rescued her from a den of cannibals in the depths of the wasteland when she was a young girl, and recruited her into your horde.
She says she's called Amazing because she does amazing things. She quickly helped you recognize her genius and volunteered herself for your team of smart men. She says you should believe what she says because she's so smart and knows most of the right things. She guaranteed that she will have very smart and very strong children.
You show Amazing into the plush quarters you've made for her deep in the heart of your fortress. She giggles delightedly and tents her fingers.
