This is the list of recipes available only to either Alliance or Horde. However, non-BoP recipes may be sold to the other faction through the neutral auction house. As well, the Winter Veil recipes (Green and Red Winter Clothes), mailed out for the first time in 2007 to appropriately skilled characters, were also made available via a Goblin-faction vendor in 2007 as a 'correction' by Blizzard, and were thusly purchasable by those daring enough to make the end run into the opposing factions' "Greatfather Winter" town. The only theoretically unobtainable recipe for Alliance players is [Orcish War Leggings] which is taught by Aturk the Anvil after completing the quest.
