Dragonguard was a military group of the Dragon-riders.
They were guards, all humans from the Varvar coast, notorious for their strength and height. They used green dragonelle scales in their armor and were in charge of guarding the breeding stock.
They also protected the hatchling and the eggs: bearing green scale was intentional because young hatchlings reacted positively to the color and the scales of their mothers.
They were employed during the Insurrection on the Isle of Ice, but proved unable to suppress it, and most of them were killed.
