The elders have felt a disturbance amongst the elements. The Dark Iron dwarves have summoned a foul spirit into our world that threatens to plague our lands with an eternal draught. This disharmony of flame must be investigated.
Travel to Blackrock Mountain, through the Chasm of Flame, into the quarry. It is there that you shall find this lord of fire: Overmaster Pyron.
End the disruption and return to me.
This cannot be... it must not be. The destruction of Pyron has merely lifted a veil. Within the depths of Blackrock is a much more insidious source of corruption.
