::A few things you should know about this faction::
:: Quarter Master's Goods http://www.wowhead.com/?faction=1119#items ::NOTICE:: there is no tabard available with this faction, dailies/quests are unfortunately the only ways to harvest rep.
:: Unlocking the Faction :: discovering this rep faction includes a 16 quest chain, at the very end the faction is discovered and you gain your first 22000 rep. Do not be alarmed, you start this faction at hated status... its a long grind, the sooner you unlock this faction the sooner you can begin the dailies.
First Chain begins with " They Took Our Men" http://www.wowhead.com/?quest=12843 Many of our guildies have already discovered that they did a portion of this chain during their quest grind to lvl 80, if you are unable to pick up this quest in k3 inn I recommend retracing the steps to find out where you left off. This chain does offer a good amount of xp for those not yet 80, but does require a flying mount at certain stages of the quest chain.
:: Other quests and dailies affiliated with this faction:: You will find a list of rep harvesting quests in this list, this faction is notorious for releasing rep at the end of a long chain of quests so be sure to research. Dailies also appear to be unveiled at various rep stages in the grind to exalted. http://www.wowhead.com/?faction=1119#quests
