1 and 15 for either/both orin and durge games
Thank you so much for both the ask games and the ask, these questions are fantastic. I'm a sibling-haver and tragedy enjoyer, so fleshing out Bran and Orin's relationship holds a ton of appeal for me, and I answered all four (and not briefly, though I did try).
CW past this point for mentions of most of Durge's usual suspects: kidnapping, indoctrination, imprisonment, torture, desecration of corpses, suicidality, stabbing, and murder.
1.1 When did your Durge and Orin meet? What was their relationship like initially? Did their feelings towards each other change over time?
This is a scene I desperately need to write. I have their first meeting almost fully mapped out in my head, but I'll try to summarize enough backstory to make the gist of it make sense.
Bran was kidnapped into the Cult of Bhaal at 16 or 17, and they spent their first month trying to escape and refusing to kill anyone outside of duels. Bhaal wasn't willing to cut his losses, so the Tribunal decided to try desensitize them to killing indiscriminately. They put Bran in a cell with a non-Bhaalist cellmate, and when they killed them, they replaced them with a new one. It convinced him his urges were inescapable, and after months of it, Bran was entirely past his breaking point.
Orin, at 10 or 11 years old, snuck in and saw them kill their latest cellmate when Sceleritas wasn't there to witness it, and she was impressed and envious of how easy they made it look. Afterwards, Bran talked her into telling Sceleritas that he'd killed without regret and was finally ready to be let out, promising to teach her what he knew. It saved them from spending much more time imprisoned, and upon release, Bran proved themself to the Tribunal with the murder spree depicted in Blood in Baldur's Gate, which secured their freedom as well as Orin's admiration.
Their first meeting more or less tricks Orin into seeing them as a role model, which she only begins to unlearn years after the fact. On the other hand, it sets Bran up to see her as the reason they're still alive, which quickly turns into their biggest reason to keep living as they become attached to her. He begins to see her as a little sister very quickly in the process of "mentoring" her over the first few years, and he dotes on her but still keeps her at arm's length to try to avoid killing her himself. As Bran acclimated to the Cult and began climbing the ranks, she remained their favorite person there by a very wide mile, and she became more or less untouchable within the Cult because of it.
He promoted her to his second in command as soon as he'd secured his own leadership three or four years later, and almost everyone around at that time resented her deeply for it. There seems to be a ton of resentment for Orin within the Cult in-game, and I think a lot of it can be explained by Bran's favoritism/nepotism in addition to her own idiosyncrasies.
The biggest source of conflict between them is that Orin grows up and begins to see Bran for something closer to who they really are rather than as her childhood idol, but Bran never does the same. They still see her as the kid sister they loved, not an adult who is realistically their greatest threat as next-in-line. Orin's feelings change, but Bran's never do.
2.1 There's a lot of reasons Orin might want to stab Durge in the head and take their place as Chosen. If it came down to one thing, what was it? What was going through her head as she stabbed your Durge?
Orin became bitterly disillusioned with Bran as she got old enough to recognize their differences. She spent about a decade as their second in command, which gave her a lot of insight into how they ran things—functionally and efficiently, but in her view, artlessly and without enough devotion. She hated that he didn't value her artistry or her input on how to make his killings more worshipful, and that he worked with outsiders just as closely as he did with her. As their relationship with Gortash progressed, she hated watching them become willing to make more time for him. She couldn't understand why Bran still refused to let her kill Enver when she only wanted to for their own good. I HC her as aroace and sex/romance repulsed, and I think between that and her upbringing teaching her to thoroughly devalue empathy, she literally couldn't fathom why Bran cared enough not to kill him and move on, regardless of how useful he was. The fact they did frustrated and confused her for years, and she saw it as an open weakness. After years of Bran refusing to excise it, she came to the conclusion they were weak, and had to die.
Refusing her challenge was, to her, the ultimate betrayal and disrespect, and it was her last straw. She'd been picking fights (verbally) and trying to provoke Bran for weeks, and she'd been sure she'd worn him down enough for him to get past his attachment to her and finally let them fight for real. He didn't, so she no longer respected him enough to want to kill him in a fair fight. As she attacked him, she reasoned that leaving him alive was a fate even worse than death, and that it was a fate he deserved for his unworthiness.
In some ways, the duel she challenges them to in-game is her trying to fix this mistake—at first she wonders if not duelling them officially is the reason why they didn't simply become a thrall or die, and I think that despite everything she has an unconscious, grudging respect for the fact they didn't. For me, this helps explain why she goes to all the trouble she does in Act 3 rather than simply finishing the job and moving on with her life. In a way, she sees it as a chance to redeem herself for her initial failure/impulsivity and make it up to him, and it even gives Bran one last chance to redeem himself in death.
1.15 What did Orin and your Durge dislike the most about each other?
This is a fantastic question for Bran because it's so easy for me to answer: above all, they disliked Orin's zeal. He resented her because, in his eyes, she had choices that he didn't, and she chose to strive to be a perfect Bhaalist when she wasn't compelled to in the way he felt he was. He was more or less groomed to lead because his urges and his blood gave him "favorite child" status (along with a decent helping of the sunk-cost fallacy), and he resented her ambition because he largely still hated his role and was convinced she shouldn't have wanted it.
Part of the reason she does is because they did so much to raise her, but they don't like to acknowledge that she's partially a monster they created, and they don't consciously reach that conclusion until after they kill her in their in-game duel. Bran came to accept being a Bhaalist leader because their induction to the Cult convinced them they could never be anything else (other than dead), but they think she could and simply chooses not to. He sees her zeal as a waste of both freedom and potential. Killing artfully and being an assassin makes her happy, and they don't see why she isn't content with merely continuing to do that.
I don't see their view of her agency as accurate: Bran was largely raised outside the Cult of Bhaal, and Orin was immersed in it more or less from birth. Realistically, she had as little say in what she became as they did, or maybe even less, and I think on some level they might hate that most of all. Bran is subconsciously jealous that her faith is so sincere because if he was honestly a zealot like her, his life would be a lot easier.
It's also an easy question for Orin for me, because I'm inclined to take her at her word in-game, based on her notes and how I imagine Bran's behavior before they were tadpoled. She dislikes their efficiency, but the thing she hates the most is their attachments to outsiders. Things like the "slip-sliding in filth with these pigs" line feel a lot deeper than simple insults to me—she seems genuinely offended on her and Bran's behalf as Bhaalspawn. I interpret this partially as unconscious jealousy, but she also legitimately sees it as a weakness and a flaw, and that is her main motivation for attacking them.
2.15 Does your Durge keep anything to remember Orin by, after her death? Did she keep anything to remember them, after her betrayal?
Bran is very much inclined to hate the Bloodthirst dagger, but he kept it after her death rather than throwing it away like he (and most of the party) wanted himself to or even giving it to Astarion to let him put it to good use. It's a symbol of what he used to be and everything he hates about himself, despite his relative lack of memories, but he remembered just enough to care about her instinctively and deeply regret killing her. They can never bring themself to use it, but they are never able to get rid of it either.
I HC that Orin threw away or destroyed Durge's things after usurping them, as opposed to Durge living a super minimalist lifestyle or some other explanation for why they have so few possessions left. Bran's bedroom would've been coated in plants and whatever magical grow lights he'd needed to keep them alive (he grew them for poisons, but also as a druidic guilty pleasure), as well as books and alchemical supplies, at minimum, so she would've had to have gutted all of that. She didn't keep anything from Bran other than Bloodthirst, but I do think she subconsciously regretted that.
She cut off Bran's long hair when she tadpoled them, both to make it easier and out of spite, but she left their braid behind somewhere in the mind flayer colony. There are a few indications that she likes keeping trophies from people she kills (her mom and her armor off the top of my head), but I think the fact that she pivoted to leaving Bran alive would've been enough to disrupt whatever her usual ritual would be. I can't decide whether she realized that she could've gone back for it afterwards, but I kind of doubt she'd let herself if the thought had ever occurred to her because she wouldn't think Bran deserved that level of sentimentality.
By the time the impulse to get rid of their things wore off, all she had left was Stillmaker, and I am a huge fan of the HC (fannon?) idea that it was something Gortash made for Durge (I cannot find the specific post I'm thinking of, but I will link it in a reblog whenever I finally do). She deeply hated both it and their relationship, so I'd imagine that she either got rid of it/gave it up or hid it in the hole where you find it in-game after she couldn't find an easy way to break it. I can't remember/find if there was a different canonical reason it ended up there, but if this does diverge from cannon, I don't know that I'd care enough to change it.
If she'd won and killed them in their in-game duel, she would've made sure to keep a trophy that time around. She might've mounted their horns on her wall or even kept their whole body like she did with her mother.
