Symbols

The McCall Pack (also known as Scott's Pack) is a pack living in Beacon Hills, California that is led by the True Alpha werewolf Scott McCall. The pack is unique in the supernatural community, because it is not only made up of Werewolves but it also has a Banshee, a Thunder Kitsune, a werecoyote, Humans and now Chimera. Additionally, the pack has a great network of allies of all different species to help them when they need it, including Hunters, Mercenaries, Werewolves, Kitsune, Hellhounds and Humans. The McCall Pack Emissary is Alan Deaton. 

The Hale Pack is a centuries-old Werewolf pack that had been led by a number of different Alphas over the course of its existence, including (but not limited to) Talia Hale, Laura Hale, Peter Hale, and Derek Hale. The earliest known Alpha of the Hale Pack was Talia Hale, who led the pack during the late 20th and early 21st century until January 2005, when she and the majority of her family and pack were killed in the Hale House Fire set by Kate Argent and her cohorts. Afterward, the status of Alpha fell to Talia's eldest daughter Laura, though whether she naturally inherited the Alpha spark upon Talia's death or gained the power through other means remains unknown.

The Triskelion. The symbol used by the alpha pack. This symbol is obviously much like the triple spiral. Unlike Derek's this can't mean Alpha, Beta and Omega, considering... it's an all alpha pack. The triskelion (especially with those foot like endings) generally symbolizes moving forward, action and competition. But that's really only the first part, then you dive deeper into it and it can represent those triplets that we see with the triple spiral. In this case (the alpha pack) I feel it means something similar to creator, destroyer and sustainer or creation, preservation and destruction. Either way, I think it has to deal with how the alpha pack thinks that they can go around passing judgement onto the rest of the werewolf population, how they can keep it going strong and cut out the weak links in order to let newer and stronger links to pop up.
