Not 100% sure of the name; it's the quest given to you by Synsomething at the Bonfire area in Thanalan that allows you to create materia when you've done it. When the main story took me there, it wasn't available, which I found odd, but thought I might it unlock later when I joined a DoH class. I'm now at level 50 (WHM) and a level 19 Weaver, and still nothing there. Not even a locked quest. I've even done the quest to meld materia, but I can't access the quest that lets me make it, and I feel a bit embarrassed not employing materia at this level. Am I doing something wrong? Is there something I've missed?
