Armor (plate), artifact

The forges needed to make this alloy were thought to be lost to time until an elite party of adventurers found a secret tomb of a lich king deep in the underdark, after defeating the lich king the hidden door to the forges were revealed to them. After making a safe passage to the forges, the dwarf kings finally returned and began to forge these alloys for the first time in centuries.
