If you are interested in helping Sagorne Crestrider in Orgrimmar's Valley of Wisdom, bring him an Azerothian Diamond and a Pristine Black Diamond.
[player], there is a pressing matter I hope you can help with... both materially and spiritually. Allow me to explain.
Within the depths of the Scholomance in Lordaeron is a chamber called the Great Ossuary. I need to complete a device that would pierce the shadows of this horrid room. To finish what I have started, I need two diamonds: an Azerothian and a Pristine Black. These are not trivial items, I know - I just don't have the resources myself.
Could you provide me with one of each?
