Field Commander Romus at Honor Hold wants you to kill 8 Shattered Hand Legionnaires, 4 Shattered Hand Centurions, and 4 Shattered Hand Champions.
We know precious little about the Fel Horde presence in Hellfire Citadel and our information has come at the cost of many lives.
Fel Horde troops under the command of Kargath Bladefist are a brutal, battle-hardened lot fortified by foul magics. The elite of this force, the Shattered Hand legionnaires, champions, and centurions are feared by the regulars and serve as an officer corps.
Targeting and eliminating them is a necessary first step in any successful assault on the Fel Horde's leadership.
That is excellent news, indeed, <name>. With progress to report from Hellfire Citadel, perhaps we can afford to turn our attention to the Fel Horde presence other parts of the peninsula and Outland as a whole.
