Over the course of The War there were many factions, one of the more powerful of these factions were the Dragons. A faction that almost came close to a sort of victory had not several other factions rallied together and virtually eradicated all of Dragon-kind.
There were five Dragon Captains at any given time, one from each of the Chromatic Houses, and were the generals or champions of their time.
The Regeant of the Red Flight
The Baronot of the Black Flight
The Warlord of the White Flight
The Governor of the Green Flight
The Bard of the Blue Flight
It is unknown if the Metallic Houses followed the Captains or were allied with them in anyway. They were however included in the mass extermination of the Dragons.
