Packs-what they stand for

So. I'm new, and I want to join a good pack that is right for my character. If at least one wolf from each pack could tell me what their pack represents, that would be very helpful to me and possibly other rogues interested in joining a pack. Put things like "the Somnus pack values..." or "The Noctis pack is for wolves that like to..., if possible.
Thanks! Myst
