Yes I think I have. He is the one on top of the building with the 2 Lore page items right? The Dwarf and Dragon ones correct? I have started his quest line for us and made it as far as going to the next NPC and back to him. But the mob we need for the next one is in the labyrinth I due believe.
One thing I kept meaning to post I think the Dwarven Relic item he sales should be removed as the Dwarf in the center of town has it, unless it is the Dragon version then i withdraw it. At the time I did not think to check to see if the one on the Dwarf is scribeable by dragons.
