While it's true, I do seek knowledge, an artifact of such power, would only be traded for something of immense power itself. To learn is to teach, to take, is to give. Only something as powerful, or as meaningful as that which you seek, would be considered for a trade. Now, as for a basic one as you put it. I'd suggest the blacksmith. That tip, I will give you for free. Seek him out, and you'll find the transaction is easier than asking me.
