Name: Orthac, the Dragon Lord (in Exile)
Age: 4027
Gender: Male
Rider: "My domain has been stolen, but I shall not be further humiliated by the murderous mortals!"
Ability: His breath can take and give life, and slaves those he raises to his will (Only works on the recently deceased)
Personality: Orthac lived through the days of the Dragon Hunts, and has long since grown distrusting of the mortals. In times long since passed, Orthac ruled over a large domain of dragons, titling himself the "Dragon Lord".
A proud Dragon, he demands that those in his presence use etiquette fitting his former post. He harbours a grudge towards the mortals, and has long since wished for some form of reckoning or reparation for their cruelty. 
History: Through the era of the Dragon Riders, and still his domain persisted, proud, powerful and prosperous under the banner of the Claw... with the Dragon Riders, man grew more comfortable around the dragons, and for the first time Orthac counted humans among his subjects. For a time the two lived peacefully, but it was not to last
Darkness descended upon his domain in what he came to call "The Great Betrayal". Man questioned the Dragon Lord, demanding to be ruled by Men. The Dragons asserted their right over the land, saying that it was humans who had come into the land, and in doing so accepted the laws of the land. And so the two sides argued, and argued...
Until one day man grew tired of arguing. They rose up, taking the dragons by surprise. The war was bloody, but inevitably mans numbers won they day, overpowering the dragons. 
The remaining dragons fled their lands, vowing to one day they would return and take their home back once more. They hid in the mountains until the bloodlust died down.
Eventually, they made themselves known again, and have petitioned the Kingdoms last few monarchs over the return of their lands... Something which has never been granted. Over the years, they have grown more and more disgruntled, and verge on the edge of militant action. 
Appearance: Orthac is a fearsome dragon of terrifying size, being several meters longer and taller than the average dragon. His scales are thick and black, scars scattered across them from various battles. A long scar on his chest marks the location of his heart. His jagged teeth and claws are razor sharp. His reptilian eyes scour those before, refusing to grant innocence to the mortals he holds responsible for the Great Betrayal...
Other:
The Dragon Lords domain of "Aazathiel" encompasses part of the Kingdom which has since become a major economic zone, constituting 21% of the kingdoms GDP. It constitutes 13% of the Kingdoms lands and has 11% of its people. The Army of the Claw contends that it is their land and that its people are illegal occupiers.

 Name: Karthul
Age: 3031
Gender: Female
Rider: "I shall have no captain but my lord."
Ability: Frost Breath
Personality: Orthacs right hand, Karthul serves an advisory role. More cautious than her Lord, Karthul spends much of her time dissuading Orthac and the other dragons from trying to destroy the Kingdom, believing such would only lead to their destruction.
Appearance: The Grey Dragon is average in size for a dragon, and he looks less ferocious than Orthac. Her scales are certainly less scarred. In spite of this, she is still terrifying on the offensive. 
Other: Orthacs remaining servants are in hiding and await the word of their master, ready to return to their ancient home... And like Orthac are preparing to reclaim it by force if required. This "Army of the Claw" may not be large in numbers by mortal measures, but the possibility of an invasion by dragons strikes fear into the hearts of those living in the Dragon Lords former domain
