Demdro Dax was a fourthling mine sergeant of the Prade Phraxmine, and an old friend of Gart Ironshank's from when they served together on the sky-taverns of Great Glade. In Weird New Worlds, he sold five crystals of stormphrax to Forden Drew and Gart Ironshank directly at the head of the phraxmine, a highly illegal activity.
