My character is basically a set of Stats with a high AC, and I would like to make her more interesting. Other than having a background as being a 'Soldier' who served in an 'Orc Battalion', she is what you would call "the normal soldier" in that she's about 'Duty', is 'Brave', 'completely sane' and 'practical'.
It's weird playing her because she's the ideal tank, people go "OMG OMG I don't want to tank", I do all of the front line stuff (as in, I tank everything, e.g. 8v1) and then when I ask people if they think Human is a good character, they're like "I don't know" even though I literally have my character standing at deaths door every game for their sake. . .
I will give some brief advice. I believe you should make a character, and by extension character personality, that you would enjoy and have fun with. Something fun to watch, play, and interact with. Also make sure your character and personality doesn't hurt the fun of others. In a horror/suspense themed campaign don't make your personality "little miss sunshine" because she wont fir the world and will likely make the world less immersive to the other players.
Likewise don't make a character that is generally a jerk that does things like betray, steal, humiliate, or bully your fellow players unless your running an evil campaign and everyone is cool with that kind of character. I realize most of these examples don't apply to you specifically but the principles behind them do.
If there is an overt theme or tone to the world you can try to tailor your character's personality to the themes and tones of the world. For example in the horror/suspense theme world instead of being "little miss sunshine" (cheerful, kind, wants to bring light to people's spirits by making people happy) you might choose instead to be the "righteous light" - defiant, full of zeal. Righteous fury fighting the corrupt and most of all wants to bring hope to the hopeless. Both characters bring "light" to others but both have a very different tone or feel in the way that they do it.
Otherwise find something about soldiers you find interesting. You can look for tropes about soldiers and think about what you like or dislike about them. You can choose to employ them or turn them on their head doing something very different or completely opposite of them. Or you can look for something a bit more realistic regarding soldiers in general that you think would be interesting to play, watch, and interact with.
I don't exactly know how you have been playing the character in terms of role play personality but try to pick something roughly in line with how you have been currently playing her personality. People don't generally have drastic personality changes for no reason and an abrupt change might be jarring to play or behold or believe in.
Personally I feel like one of the more interesting options for a soldier is the grizzled/retired veteran - not in physical appearance, but in emotional and mental truths. Someone who has seen horrors and done things they are not proud of to protect their own life and the people they care about. You don't generally go through trauma without significant consequence and almost never go through wars of any kind without some kind of trauma. It doesn't have to be PTSD which seems to be a popular condition for fiction bases soldierly characters in recent times. It can be panic attacks, social anxiety, phobias or really anything you might see a psychiatrist for.
A character full of strength and capability that will go into endless battles and march into almost certain death over and over again to do the right thing masking the pain and trauma under a cool and hard emotional exterior as a defense mechanism that only came undone in times of peace and calm when there was no immediate threat. Good will, kindness, and goodness subverted by self loathing, regret, and fear or anger from the things you have done or perhaps the things you failed in, the people you failed to save. It's emotionally intense, rough, and provides flaws, motivations, and beliefs. A good and golden heart covered in stone and the bitterness of guilt. But that's just me.
Honestly, Human is kind of different from the retired veteran sort of trope. You see, she joined the Orc army, got trained up, helped win a war and now she's not a normal villigar and feels she has a sense of purpose rather than to hang around on an island, farm away, get married, have babies and then continue the cycle.
Like, how could you sit around after you get git buff, get labbled as a Hero Of The People for a while and theres stuff going on around the world? Wouldn't you want to continue onwards with the Orcs that brought so much to your life? In Human's case, yes but she wasn't allowed to come along so she was a frustraited sitting duck on an island doing what felt like nothing.
Then one day, she gets a letter from overseas inviting her to work for a house of royalty and shes like "snap boyo yes!




to do!", turns up is like "Why am I here again?" as she sees Wizards and men shaped machines that are far more gifted than her roaming the streets, pulling weapons out of the air with magic, summoning destructive magics, flying machines in the air and its like "well, I feel a bit stupid being here. The




do they need someone like me for?" but then, bad




happens. During one of her missions a Wizard in the party proceeds to walk through the grass and disguises herself as a guard, Human be like "here goes nothing." charges in, kills a bunch of guys and then the Wizard gets hit. Human does her best to fix her up, goes back to battle and then a few weeks later, the wizard who got one shot be like "can you do some guard duty for me?" and Human's like "where and when, I don't want to know why cause I owe you" and then the next thing you know, the Wizard slaughters a bunch of innocent people in a building, becomes a Warlock who can summon a giant fiend to serve in battle and Human be like "




. This is my fault." . . .
So I guess what I need to know is how do you pursue Justice over a player in the longterm without just straight up murdering them? If I tell the authorities then the whole operation will come undone and it'll send all of the Ebberon houses against each other so my only real option is to quitely deal with them.
