Minerology of Exile Island

Im not sure if this city worships chaos or law? I think Glorantha did metals best but...

A common spell is bless metal that activates the occult properties of metal. A seperate spell for each metal with cults and schools or cultures preferring a type.  Some metals have higher level spells. Bless metal requires a sacrifice of 1000 gp of goods or livestock or slaves per pound. Create one pound per level. One day in ritual forge per lv. Becomes as strong as steel for armour and weapons. Spell takes a day per pound. Should have as raw and pure as possible source.
