Bring a load of Umbral Ore to Tormus Deepforge in Ironforge.
My mentor, Sturgy Ironband, had a compound south of Helm's Bed Lake in eastern Dun Morogh. There he taught blacksmithing and he was the best.
But one day, one of his students brought him a load of strange ore. Master Ironband called it umbral ore and was eager to work with it, but soon after it arrived... a band of Dark Iron dwarves attacked his compound. They killed everyone!
Enter Ironband's compound, <name>, and avenge my master's death. And bring me the load of umbral ore that caused it.
