Mastering Gemology

<name>, what a splendid sight to have you here with me once more. I have noticed - and you surely, too - that your progress in the craft has grown astronomically! Really, it has been too long since I've witnessed such prodigal skills at hand. This sadly means that my means of teaching are at an end. Your eagerness to learn more is apparent however; good thing I can assist you one last time.

Should you wish to strengthen your understanding in the field of gemology, there is someone - a secretive man, that can aid you in your ambitions. Older than anything I know, he is part of an ancient order, one that mastered the knowledge over Azeroth's minerals. As such, he values his privacy; meaning he will most likely not speak with you. Here, take this crystal with you. It is proof of my tutelage under him, and it will show him you can be trusted. Please, take care on your journey to him, for I wish you the safest of travels.

<Gulmire does a short, cordial bow.>

<The stone skinned dwarf ignores you with ease, as if you're not worthy of his time.>

<Thegren's gaze switches between you and the crystal you brought with you. After staring at you for a good amount of time, he nods.>
