I am sorry, but can I inquire something in regard of new Pathfinder 2 content? The new AP #187 has released on AoN and among new monsters are Gorgas - fey embodiments of fear of dark in various forms. I imagine these could've worked interestingly in Karasutra for Planescape, since they are said to have not been originally evil, but I wonder what interesting ideas you could have for them (I am sorry if this comes off as too direct, I have no Tumblr etiquette skills yet)
No worries! Asks are always lovely and I don't get enough of them!
I think your instincts are right on the money. If you don't have a First World/Feywild equivelent (or even if you do), Karasuthra would be a logical play for Gorgas that aren't as malicious and are more just hungry. The Beastlands have a pretty long history of True Neutral (or using 4e's parlence since it really fits here - Unaligned) animals and fey on the plane, so even if they aren't actively good, I think there is a place for them. Karasuthra also has a history of hinting at dark and dangerous things lurking in the shadows, so Gorgas fit the bill quite nicely for that.
I'd also think about putting them on the Twlight realm of Brux, especially the temagyr with their cloak of shadows ability. Regardless of what plane they are on, I'd expect to find them in the courts of animal lords associated with shadows, Owl and Cat spring to mind.
Off the Beastlands, I think Pandemonium would make sense too. Caves, long shadows, fear of the dark, and paranoia just fit together way too well. And for bonus point, the Unseelie Court hangs out on Phlegethon!
