Yep, it's a very comprehansive post, well done!
Heh, well, I've shown you my notes on the game, so you know what kind of stuff I keep track of. XD
Only one error that I found: Lady Ashford is not traitorous. She didn't take her duties seriously enough and let things happens that shouldn't be, but she did not actively do anything wrong. Well, as far as we know.
No worries, I did mention that it's got some speculation, so there may be things that aren't 100% accurate. I likely jumped the gun and made an assumption when taking notes on her. I will update.
The guy you replied to who listed every character/woman in the game said Henri (MC) won't get some due to death, but whether resurrection happens hasn't been established... it's something clerics may use, and a couple good clerics died, so maybe a possibility... hard to see what they looked like, but let's not rule that out unless lore is revealed.
At a certain point I have to make assumptions and cut off some from tracking on the list, so I made some assumptions based on reasonability and what we've seen in-game so far. As soon as resurrection magic shows up, I might move some of those entries, but until then, I'll just leave it with my assumptions.
Don't remember if I said in a previous post (can't find in search) but I think gaping would add to the game...
The main issue with gaping is that the mods available for HS1 genitalia are, as far as I am aware, somewhat limited in what they can do while still looking good. Also, using one of the mods that might support it would likely result in significant changes to the appearances of genitalia for a lot of characters. HS1 just isn't as versatile as some other tools for character posing and rendering (the tradeoff being that it is still significantly easier to use than most of the other ones besides HS2, which as Vander has said did not have enough good fantasy/medieval assets and mods when he started this game, and Koikatsu, which is a wildly different visual style that is... shall we say, "polarizing").
I would've liked to have married Avila & Miriella at the same time, but I guess Miriella was getting over abusive situation.
Miriella can't marry the MC, she's a commoner. She can be his concubine, though.
