I had made a little short term pack - only lasted a few days. But it was quite interesting. My beta was russain and a previous loner and had a romance with a runty little loner we adopted into my pack. My delta was my twin sister except much smaller, she hated me (for being alpha) and the adopted loner (for being liked by me). At on point when I was offline sombody nearly drowned, and that never was explained well to me - I think it was attemted murder.
That was my first pack, it was really fun though!
