Ashen Verdict Reputation Guide

The Ashen Verdict was forged out of an alliance between the formidable Argent Crusade, led by Highlord Tirion Fordring, and the Knights of the Ebon Blade, led by Highlord Darion Mograine. Reminiscent of the Shattered Sun Offensive these two different organizations have come together for a common purpose, to lead the final assault against the Scourge in Icecrown Citadel and bring about the fall of the Lich King.

The best description of the Ashen Verdict was probably given by Highlord Darion Mograine himself:
“The Ashen Verdict is a select group of the most talented craftsmen in the Ebon Blade and Argent Crusade. Its creation symbolizes the unity of our forces as we mount the final assault on the Lich King and his minions.
It is through the Ashen Verdict's efforts that we have discovered how to bend saronite to our will.”
Reputation
With limited quests available from this faction, your main source of reputation gain is going to be inside the Citadel itself. Inside you will be granted reputation each time you manage to bring down a monster. The reputation you receive will depend on what type of mob you kill. Most normal mobs will grant you 15 reputation, however harder elites, and named mobs will grant you more. Bosses inside Icecrown Citadel will grant you 250 reputation.
There are however a few quests that you can and should do as soon as Icecrown is fully opened. The Ashen Verdict, having learned to bend Primordial Saronite to their will, have set their smiths on an epic task; to repurpose Arthas’s former weapon Light’s Vengeance (discarded once he claimed Frostmourne) to forge a new weapon called Shadowmourne.
You will assist the Verdict’s smiths in forging Shadowmourne in what could be considered one of the most epic quest lines ever seen in game:
