Gulduril

Gulduril Crystals are obtained from Gulduril Ore, found in Mordor. They can be used to craft a Gulduril Block on a regular crafting table, which has no use other than 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.
