Ragnaros has uncovered the secret to creating life from stone and plans to build an army of unstoppable golems to aid him in conquering the whole of Blackrock Mountain.
Ragnaros' name is from Ragnarök(Ragnarok), the end of the world in Norse mythology, but he seems to be based on the leader of the Fire giants, Surt.
This means that melee should be around Ragnaros generally on the south, west and north parts of the inner ring, and the ranged is on the south and west portions of the outer ring.
It is the heart of Blackrock Mountain and the exact spot where, long ago in a desperate bid to turn the tide of the dwarven civil war, Emperor Thaurissan summoned the elemental Firelord, Ragnaros, into the world.
The burning lake where Ragnaros lies sleeping acts as a rift connecting to the plane of fire, allowing the malicious elementals to pass through.
Chief among Ragnaros' agents is Majordomo Executus - for this cunning servant is the only one capable of calling the Firelord from his slumber.
