Gondorian girl #8264918636, that we will call Elfiriel for brevity's sake, is very beautiful.
She is of Dunedain descent (or so her father, a merchant, told her), but despite that she's so petite, standing only at 1.56 m; she has the typical ebony, wavy hair of her ancestors, and eyes the colour of sweet, fresh honey.
She grew up with tales of ancient times, that can be summed up as: "Don't wander into dangerous lands, you may be killed/cursed/kidnapped"
Despite this, Elfiriel does exactly what the tales warned her about: she ventures alone at night, in the woods. Of course her life as an upper middle-class Gondorian, where she had everything she needed, where she could wander around her city without a single thought in her head and still make it home safely, well, it sucked too much for her.
Anyways, she thinks she's safe anyways because she can defend herself. Spoiler: she can't. In fact, a random group of orcs (that has no reason to be in the woods, but we need them for the plot) finds her and captures her. Elfiriel maybe realised that she needed to practice more than once or twice the move that the young guard tried to teach her (in an attempt to impress her). Because you know what the thing is about fighting? That you need to practice so much that those moves become muscle memory :) It can take a lot of time :)
An uruk slaps her, which sends her KO. They decide to take her and sell her as soon as they meet some Marauders.
During the journey to Mordor, the girl tries to strike up a conversation, and fails. Because those uruks deem her an inferior weakling that's not worth their time. It goes like this:
"So uh... Where are we going?"
"It's none of your business. Shut up or that guy with the eye-patch will whip you."
"Why are you doing this to me?!"
"You shriek like a damn Shrieker and I HATE that. Make her stop Lugnak, I don't care how you do it, just don't cause too much damage."
Well, you can imagine several scenarios of what might happen.
Anyways, the group meets a caravan of Marauders. The girl is sold for 10 mirian and a bunch of jewels that the marauders didn't want anymore. After that, she's put to work in the farms of Nurn, where she eventually dies. Because slaves usually don't have long lives.
Lesson #1: orcs are awful, they hate their kin and other races even more. They don't care about you.
