Well this is its own setting right? So you can ignore or not ignore to your hearts content.
Quick question, is this purely stand alone, or is this on the fringes of the multiverse of DnD?
My character was addressing him in draconic, since he doesn't or rather didn't know draconic, but I can switch it around if you'd like. I'll at least go with Dwarvish, not sure about the second one.
