Ok check the forest before choosing a home.
Start there.
Took me a minute to figure this part out.
If I'm being honest I won't do spoilers because then here in the comments every will get the spoiler.
All I'll say is if you want her you must make sure you don't let the centaurs have fun.
Oh and avoid killing and anything that will attract her forces to quickly you want her away as long as possible to make sure you got everything and I recommend capturing all girls before she attacks your stronghold.
I played this like a year ago or maybe even more and when i got attacked by the huntress maelys i captured her no matter what I did she didn't kill herself but after the 18+ scenes she stopped responding she was like a puppet with broken mind.
Did they fix it in this version and can we save her or no matter what she will be just braindead after we do the thing with her
