It is uncertain who first crafted the Anti-dragonfire shield. The dwarves claim the honour, as do several human blacksmiths. The goblins tried to take the credit, but their smithing techniques were not nearly refined enough to be believed. The aviansie might have been capable of such a feat, but if they did craft the shield, they never said.
The aviansie that did visit Ashenfall only stayed in Brynmoor for a short time. They disappeared deeper into the continent, never to be heard from again.
The Anti-dragonfire shield is a formidable defence, surpassing the strength of iron and capable of withstanding a dragon's lethal breath. Its previous owner, hopeful it could be a weapon against Velgar, was proven wrong.
Only the most powerful individuals can hope to wield such an object. Yet, even so, it is said that the shield can be improved by combining it with the essence of a dragon, gaining some of the fury of the legendary beast.
