I am still new and am curious about the packs. Are they a work in progress or something? There is some overviews of them on wiki, and the forum pages for information on a few of the packs are private.
It took me a long time to choose my pack because I was not drawn to any of them (I am intrigued the most by Mistvale, which makes sense because I'm Nature on Flight Rising), joined as Murkwood only because of the name, and am considering moving to Darkspine. I guess I just need to get used to it being different from FR, where with 11 flights to choose from I immediately felt a connection with one. I currently don't consider my wolves to be part of any pack but their own, just living under a territory.
I suppose since they do not have much in-game function at the moment, the packs do not need much information. But if people have their own interpretations and headcanons about pack culture and beliefs, and how your wolves feel about their pack, I would love to hear them!
