Celebrimbor
The Second Age is the period of the Elven War against Sauron and the forging of the Rings of Power. Their creator was a certain Celebrimbor – grandson of the great Fëanor and leader of Gawith-i-Mirdain. I would like to see the creation of the Rings and the death of the greatest blacksmith of the Second Age. I would love to see Mark Gatiss as the creator of Elendilmir and Elessar.
