Sic Semper Tyrannis
Long after the Dragonborn were created to be the eyes and ears of the sleeping dragons, a lesser race was born. The difference between these small, piteous lizard creatures and the strong, brave, and noble Dragonborn was just as vast as the difference between the Dragonborn and the great Dragons themselves. For many years these creatures were so lowly, they were not even given a name and in the end, they named themselves: Kobolds. A name without glory or virtue, though perhaps the most effective that they could come up with.
While the Dragonborn, being such a noble race, do not believe in owning other sentient beings, these small lizards are generally no more than errand-runners for the Dragonborn and in many case are treated like livestock. However, they have a certain cunning, which cannot be avoided or quelled. This cunning has helped them create small pockets of ineffectual resistance against the greater Dragonborn cause of righteousness. These resistors work to cause mayhem and discord, seeking to breed discontent in the Dragonborn ranks in an attempt to undermine their mission to create a world suitable for the sleeping dragons.
