I am very interested in seeing how Fearne develops over the campaign, including the rakes she will inevitably step on. She seems to have two defining characteristics: One is a general impulsiveness that comes from growing up in a plane with orange and blue morality. It's a very classic fey character trait. The other is her shock statements. I used to do this when I was a kid! I would say outlandish things just to see how people (including my friends) would react. I know it comes off as lolrandom, but this is a thing I actually did growing up. So I'm especially interested to see how these shock statements evolve as she grows more mature over time.
On Reddit someone who also saw Exandria Unlimited said Fearne seems like a BBEG (Big Bad Evil Gal) in her early formative years.
