Do you happen to know how to proc the "alley" scene? I've never heard of that, or seen any mention of it. The wiki also mentions a scene if you are traveling while her "resolve" is low enough, but I have no idea how to actually lower it consistently.
I recently delved into Anyxine's content in Trials, which was absolutely fantastic and super well written, and embodies a lot of aspects that I feel align with Arona's potential. There is a strong emphasis on relationship building, and the pre-established friendship and history between them makes the emotional connection feel a lot more genuine and cathartic. There is a clear boundary set between their emotional and sexual relationship, such as with Anyxine expressing excitement at Steele being her boss in the boardroom while she's in charge in the bedroom. There is a lot of moments of genuine affection and respect as a dom, and her teasing personality and insults are in jest, and never feel mean-spirited. I also personally like most of the bimbo flavour, in that it's primarily focused on passion during the sex, and the "insults" are clearly also in jest, unlike some other scenes in Trials where it feels like characters actively degrade and insult Steele in a unfair manner, and it makes connotations about intellect. The small flavourful touches like the text messages she sends are also always appreciated.
A big part of why I enjoy the sub scenes more than the dom ones for Arona is because it felt like the champion has a much more involved presence during it, and is more actively participating, described and appreciated. I have mentioned before that content is a lot more fun when the characters actively admire the pc and find them sexy, and when they get more involved and erotic descriptions instead of the often bland sounding generic parsers. Oftentimes when the pc is submissive, they feel more like the centre of attention, admiration and beauty, getting some of the love usually only reserved for the npc's. Most dom scenes would be a lot more fun if you could be acknowledged as the gorgeous muscle bound amazon you can try to be, and your stamina and fitness were utilized more actively during writing.
I've seen Arona get a fair bit of negative reception and discussion on this forum whenever companions are brought up, and to be honest I don't fully get why. A lot of the reasons and justifications people use don't actually seem to be true or present in the game from what I've experienced. My personal thoughts are that I like what she embodies, but wish that she was more fleshed out, in both her character development and erotica, which is a bit too dry sometimes. It's also a bit of a shame that you can't have multiple of her kids at once, I noticed that a lot in Champions opposed to Trials.
As I mentioned, I am definitely interested in seeing her get more content (which is of course tricky due to commissions, work-load and the general dev plan). Traveling scenes, champion pregnancy, addiction/submission, full nelson, mating press, all nighters, a larger size transformation, there is a lot of fun potential (although I am clearly biased towards the sub content).
I greatly appreciate the extra context and info given, I'm glad development seems to be going so well.
