Ithildin

"They are wrought of ithildin that mirrors only starlight and moonlight, and sleeps until it is touched by one who speaks words now long forgotten in Middle-earth."

- Gandalf

Ithildin is a new material that was added in Beta 30. It was originally used by the dwarves of Kazhad-Dûm and

the Noldor elves settling in Eregion to make inscriptions and decorations that can only be seen under moon light, much like moon runes.

It can be made by alloying a silver ingot and a mithril nugget in an elven forge.
