The Dragonkight Legions

After the dragonborn were brought out of the Black Desert to the Good King Kalos in Nicosia, Larnaca, they organized themselves into an organization called the Dragonknight Legions. As the name implies, the army was divided into legions: five the colors of the chromatic dragons and a sixth legion of metallic dragons, although this last legion is rarely referred to as a legion, since they operate as five separate companies.

The Legions
The five legions each had about 5000 dragonknights to begin with. They were largely equivalent, with whatever legion happened to be closest being sent if a need arose, but they did specialize slightly. Each legion was led by a general and was broken up into phalanx of about 100 led by a captain.
 * The Red Dragonknight Legion were the heaviest armed and most deadly in battle
 * The Blue Dragonknight Legion specialized in magic. They are called the lost legion because the entire legion disappeared, leaving behind only three blue dragonborn that happened to not be with them at the time
 * The Green Dragonknight Legion prideded itself on being self-sufficient, and being able to go far abroad without extensive supply lines
 * The Black Dragonknight Legion, sometimes referred to as the hammer, specialized in attacking fortified positions
 * The White Dragonknight Legion, sometimes referred to as the cavalry, were lightly armed and fast moving, in both travel and battle

The Companies
The Metal Dragonknight Legion was broken up into five companies each led by a commander.
 * The Golden Dragonknight Guards protected the king. There were only 12 to begin with. Their commander was treated as general of the Metal Dragonknight Legion, and leader of all dragonknights
 * The Silver Dragonknight Diplomats, as their name implies, were used as diplomats. Every noble in Larnaca, and many foreign leaders as well, were sent a silver dragonknight to serve as an adviser. There were about 300
 * The Copper Dragonknight Rangers served two purposes: they patrolled the roads within Larnaca to keep them safe and they scouted the borders of the kingdom to warn if enemies approached and to handle them if able. There were about 500
 * The Tin Dragonknight Enforcers served as the elite police of Larnaca. There were about 1000
 * The Zinc Dragonknight Defenders protected Larnaca from forces from beyond Rojopotis. Their were about 1000
