i’ve been writing marcie for a long time now and her new vegas verse is a bit dusty so here is her long story short: marcie was captured by the legion, spent about 8 months with a bomb collar, stabbed the same guy multiple times, and was taken in by the ncr. they interrogated her for info on Dead Sea (said stabee) and the Legion in general, and after she willingly gave them as much info as she had (which was plenty) the ncr hired her as a seamstress, and let her work towards ncr citizenship. her plan was to move to sandy springs eventually.
a few months later, she was seen by the head of the Office of Public Relations and after hearing her story, they hired her as a model for propaganda posters, appeared in charity calendars, and eventually they had her write a heavily sanitized version memoir, mostly of her time under Legion subjugation. it was a best seller, and she is now a ncr socialite, appearing at soldier and officer events, and being sponsored and appearing in ncr-approved advertisements. her official title is “Goodwill Ambassador”.
eventually she tires of her tightly controlled public persona, and dealing with the trauma of her time with the Legion, begins acting out (breaking away from her bodyguard multiple times) the ncr begins to reduce her public activity and restricts her to seamstress work, until they come to an agreement.
they give her unsettled land in their Oregon territory, and years later the Lindell Township opens, making her the de facto mayor. she runs a brahmin ranch, and more people begin moving to the town. eventually she re-enters public life, running for a seat in the ncr congress, which she wins. thus begins her life as an ncr brahmin rancher politician.
