The helm from this set is a BOE world drop. The chest is dropped from Lord Aurius Rivendare in Stratholme, Ebonroc in Blackwing Lair, or Cenarion Expedition - Honored. The gloves are dropped by Ossirian the Unscarred in Ruins of Ahn'Qiraj, and the legs are a horde-only reputation reward from the Mag'har.
