Ok.
You need to add some details to her. And you need to express those details at the table. The other players have to know her story somehow.
How old is she?
How does she dress? What's she look like?
Where is she originally from? What's her actual name? (even if she doesn't know these answers herself)
Is she concerned with returning to her home/name/etc? Why or why not. How does that effect her?
Add a few details about her human family.
How & when did she come to be fighting along side orcs?
Does she have any orc friends/family/allies/rivals?
How does she feel about orcs? Other races? Men/women/children?
What's she seen & done with the orcs?
What did she do that other orcs wanted to see "The Human" in action?
How/why did she leave the orcs?
Why is she doing whatever she's doing now?
And, other than fighting, what does she do? What would she like to do?
She's 23 If I remember correctly
She wears armour all of the time, Splint Armour at the moment. she doesn't actually have 'normal clothing'.
She's from a large island up to the north-west of Eberron
She doesn't know her name. She went by "kid", "girl", "her" and "orphan girl" though she wasn't homeless.
She isn't all that interested in going home. She's very much a person who is all about "now" and "later" but not "the past" or "future". It kind of means she's going-in blind.
She didn't really have a family. She doesn't believe she's even from the Island she was raised in. She just got by with a bit of help from the other Villigers and the Orcs who visited the town.
Orcs were going around town to try and recruit half-orcs who lived there, instead they got a Human asking to join them. It seemed too funny to them so they just let her.
She doesn't exactly have friends . . . she kept things professional. If your life is work and if mucking up means death . . . well, she didn't muck about to say the least.
She knows that most people are biased towards them so she tries to give context as to what is wrong with their mentality e.g. have you ever tried to negotiate with an Orc before instead of just trying to kill it? She's also more . . . adjusted with killing people of other races (even Humans) because things are more black and white to her. It's an Enemy, it's dangerous and thats it. She's also disinterested in talking to people . . . joining an Orc army at the age of 17 and becoming a very serious Soldier kind of does that to you if you don't try to open up to people.
She has trained with Orcs, been trained by Orcs, learned how to speak and read Orc, she has eaten with Orcs, camped with Orcs, fought with Orcs, hunted with Orcs . . . pretty much everything with Orcs except for befriending them or love making . . .
She's not sure about what she did that was great. She grew strong enough to spar with them and when she came across other fighters who wanted to duel with her, many didn't see why the Orcs liked her either.
Her work was done, they let her keep her armour and weapons and told her to find something else to do. That's pretty much it.
She believes that she is a soldier and thus should function as one.
She has very much been about 'staying alive' and has thus made every effort to prepare for her work (e.g. exercise, buying supplies, sparing etc.) though I'm pretty sure that she feels there is something missing in her life and is kind of bored.
