The Sacred and the Corrupt
Place Light's Vengeance, 25 Primordial Saronite, Rotface's Acidic Blood, and Festergut's Acidic Blood in Highlord Mograine's runeforge in Icecrown Citadel. Rotface's Acidic Blood and Festergut's Acidic Blood may only be obtained in the 25 person difficulty setting of Icecrown Citadel.
It is against my judgment that I present you this errand, <Race>, as it will likely end in your undoing. Ignore my counsel and embark on the endeavor, and I shall provide you with the knowledge and resources to see it through. You must return to Frostmourne Cavern and recover Light's Vengeance, Arthas' discarded hammer. Reforged with saronite and etched with the acidic blood of the Lich King's abominations, it will provide the foundation for our work.
