Gulduril

Gulduril Crystals are obtained from Gulduril Ore, found in Mordor and Angmar. They can be used to craft a Block of Gulduril on a regular crafting table, which currently has no use other than as a light and decoration. Right clicking on a Mordor Brick block will turn it into Gulduril Brick, which is used in the creation of a Morgul Portal. They can be alloyed with Orc Steel in an Orc Forge  to make Morgul Steel, which can then be used to craft Morgul Armour  and the deadly Morgul Blade. It can also, be used to create Morgul Torches, the main source of light in Angmar
