Both Orcs and Men are known to have drinks with similar restorative properties to Miruvor, although the Elven brand is more powerful than these others.

The western door of Moria is made from ithildin (see glossary). Gandalf knew the necessary invocation by which the ithildin would be revealed. The gates were made by the great Dwarf craftsman, Narvi, with the help of his friend the Elven artificer, Celebrimbor.
