@anim-ttrpgs just put their historically-accurate souls-like ttrpg Death Bed: An Impenetrably Medieval Dungeon Game into playable beta, so after reading through the book and rolling up a few strugglers, I was inspired to try and draw one of them;
this is Aoife The Rat, a left-handed, red-haired peasant-woman who is a known thief, liar, knave, cur, etc.
I also want to talk about how Death Bed's rules and mechanics inspired me to make this character, and how I've been able to flesh her out from just reading the rules of Death Bed;
Part of character creation is to write a 'Truth' for your struggler, a word or sentence which represents an aspect of their personality that they get bonuses for following. Aoife's Truth is Never More Than A Rat, representing that she sees herself as trapped into the role of a lowly vagabond, never allowed to reach a higher status by those above her. If they call her a rat, regardless of how hard she tries to get their approval, she might as well reap the benefits of actually being one, right?
Death Bed also has an important and fascinating mechanic where every character has a Social Status score, which directly affects how two strugglers are likely to interact. A struggler can pull rank on other strugglers with lower social statuses, telling them what to do or face consequences. If the difference in social status is high enough, it is even within the higher-ranking struggler's right to strike the lower ranking struggler whensoever they please, and are in fact encouraged to in situations like when Aoife's sharp tongue and arrogant manner drive her to insult those high above her station.
All of which- being forced to obey rules, getting kicked down for disobedience or anything perceived as acting out- has the very real consequence of hollowing.
If you've played Dark Souls, you're already familiar with the idea; a character loses their sense of humanity, they slowly rot into a living corpse until they lose any sense of self and become a violent, shambling husk. A lot of ttrpgs claim to be 'Dark Souls-inspired' by being vaguely gothic fantasy, but Death Bed actually feels like The Dark Souls ttrpg.
The left-most depiction is a fully human Aoife; the right-most is her fully-hollowed self on the brink of becoming a mindless zombie. Each stage of hollowing has mechanical disadvantages (reduced vitality, loss of senses, more distrust from others, as if Aoife needed more of that), and at the worst stage, unable to speak. But it also has a few advantages as well (increasing immunity to bleeding and poison, not needing to breath, etc.)
In Death Bed, hollowing doesn't just occur when your character dies; they slowly hollow whenever they face extreme stress such as watching someone die, retreating from combat, or committing serious social faux-pas. Death Bed is impenetrably medieval; social decorum matters a lot.
The Social Status mechanic was the main inspiration for making Aoife; she was designed to have a social status as close to 0 as I could get, both by aspects of her birth (being red-haired and left-handed) and by her own actions, like being a practiced thief and extremely paranoid. (Though if you asked her, those stemmed from the aspects of her birth as well.)
You can see how, even mechanically, the world has taught Aoife to believe she will truly never be more than a rat. At which points that stops being a pessimistic truth of her life and where it becomes a self-fulfilling prophecy and an excuse is difficult to say.
All of this stemming from and directly supported by the rules of the game, and at no point butting heads with or going against the rules for the sake of narrative.
