The metal is made from a sacred alchemeic metal, called Electrum, which is an Ancient Egyptian Formula combining all four elements, the essence of the five other realms, also known as the essence of AmunRa - it consists of gold, silver and platinum. There are other things included, but that would ruin the secret. Finnally, the metal is made by a purifier, a singer and of course the alchemist priest. This is fatal to all who are spiritually impure - those that would prey upon the children of Nebetcher. (vampires, wearwolves, demons, serial killers...)
