Metals are known for there gem like appearance but they are different,since there skins and there ores (there gemstones)are tougher,and since I figured out that Tungsten is the strongest known to man,tungsten would be the Emperor (or empress) but for later about 1,000 years tungsten is replace with new Dynasty,the Sliver Dynasty.

BEHOLD THE EMPEROR!

Yea founding some artwork is hard to find so I'm gonna do some tough writing on the other gems

1 Titaniums
Titanium's are like solid bodies made out of titanium like skin,they have no face and head,just a eyes,there like giant gorillas.they are the elites

2 Copper,bronze,and brass
They are the engineers,there like rubies,but without the hairdo and are orange

2 Steel
They the basics infantry

(And I'll stop here)
