Gold

Gold is one of the valuable metals. Due to it's atomic composition, gold does not react very well with other atoms and molecules and therefore doesn't oxidate like other metals do, (like iron rusting). This causes gold to maintain it's shiny, yellowish hue and is attractive by most races on the mortal realm. It's a commonly used form of currency, and a symbol of money there-of.

Gold resists most types of acids (not nitro-hydrochloric acid, mercury and alkaline solutions of cyanide), but other than this, it is not a very strong or hard metal. On top of this, it is a very heavy metal and therefore weaponry and armor isn't favorable to be made of gold. Gold trims, however, could be used on high-ranking officers, kings, nobles and the likes to show their status. Gold also seems to be capable of holding powerfull enchantments and is able to channel a large amount of arcane energy within it.
