The Argent Dawn are the protectors of Azeroth and can now be found in Northrend as well.

"Reputation rewarded for killing mobs will no longer automatically deprecate. This means trivial mobs will continue to give out their full amounts of reputation on kill for the majority of cases in the game (level 70 creatures in Stratholme, for example, will continue to award the full amount of rep to level 80 players seeking to boost their Argent Dawn faction)." Patch 3.08 Notes.
