Iron Ore / Ingots / Powder. What is it for? I looked at all the crafting tabs for market vendors. Not seeing anything to craft with it. I haven't found an iron ore service yet. Oddly, they're a common item but I can only assume the iron service items are locked behind question completions. Throwing weapons, lockpicks, and traps.
