Yuppers, you'll want to have your kobolds build a torture chamber in Act III. You can then either send Naho there immediately, which breaks her will and gets her hooked on wolfnettle. Or you can try to make her your consort without breaking her... which leads to either killing her, removing her as a consort or... breaking her, again, with slightly different dialogue options. Still wish there was a way to avoid breaking her, but I'll settle for having Naho content at all. Maybe we can 'un-break' her later.
