Doors of Durin

The fabled Doors of Durin, outside Moria, laced with enchanted Ithildin.

Ithildin was a type of specially crafted Mithril that only the most experienced craftsmen of the Noldor could learn how to make and pass on to others.


It was made out of extremely refined Mithril, which was thinned out to the point of being a sort of lining for which things could be laced with. It was so thin that it could be used by inscribers to write special runes, known as moon-letters, such as those on Thorin Oakenshield's map. It was enchanted so that it only appears in moonlight or starlight, and could be enchanted further so that it would never appear except on a specific phase of the moon on a specific night, or only when certain words were uttered in its presence. It was used also on the Doors of Durin in the Second Age.
