The Blood Furnace is the second wing of the Hellfire Citadel. The instance takes place above Hellfire Ramparts, inside of the tower that overlooks the ramparts themselves. The entrance is on the Alliance (Southern) side of the Citadel, up a ramp that starts at map coordinates . You come to find out, in the course of the instance, that it is Magtheridon that is entrapped by the fel orcs' sorcery, and they're using his blood to manufacture a new Fel Horde, infused with his demonic energy. The guiding force in this plan is Illidan, who is now the supreme ruler of Outland, after his usurping of Magtheridon.
The instance is around one and a half times to twice as long as Hellfire Ramparts, and has the same number of bosses. Like Hellfire Ramparts, it can be finished by a party of level 60 characters, though it will take a more balanced group and/or better geared and skilled players. This instance is substantially less difficult for solo farming than the Hellfire Ramparts, although with a correspondingly lower gold yield.
For years, this gargantuan fortress was thought to be abandoned, but it's now inhabited by marauding bands of red, furious fel orcs. The presence of this new, savage breed presents something of a mystery, though what is far more disconcerting is that the numbers of these fel orcs seem to be... growing.
At the heart of Outland's barren Hellfire Peninsula stand Hellfire Citadel, a nearly impenetrable bastion that served as the Horde's base of operations throughout the First and Second Wars.
