[x] Obsidian dwarves
I will try to give an argument for Dwarves and against Demonkin.
To begin with we are a orderly society in general, being made by the Dragons as Servants, with Demonkin being chaotic enough to be ungovernable. It would also mean Demons are taking an interst into us, which I take as a bad thing. Obisian Dwarves on the other hand are defectors and fought with us for the Dragons, who we both miss. They would also be a great help in the Underdark itself with their affinity and they mirror us in the want of knowledge.
