The weapons are ready to be forged. You must take the tempered azsharite to one with the ability to harness fel energy.
In Stranglethorn Vale such a blacksmith exists. Galvan the Ancient, leader of the Mithril Order, will craft the weapons to your specifications. You will find his encampment between Zul'Gurub and the Mosh'Ogg ogre mound.
May your determination and faith carry you through this ordeal. Should you fail, know that your God smiles down upon you, mortal.
