Kobolds

Kobolds maintain their indebted attitude toward Dragons, aspiring to eventually become them, wishing that the Dragons and their kin once again ruled over the lands of Nevandaar. They keep their cowardly, wiry and trickster aesthetic, and their mannerisms are almost identical to those of the 5e Sourcebooks bar a couple of differences:

Historical Savants:
Kobolds are not intelligent, not in the slightest in most cases. However if you ask a Kobold something pertaining to the history of their race, of Dragons or the Dragonborn, chances are the little creature has spent so many restless nights learning about their heroes that they can recite it in their sleep.

Kobolds maintain plentiful amounts of documentation on just about anything they do. They believe when they ascend to becoming a dragon (which many of them still believe despite it never happening), their little diaries and documents will in turn be read by Kobolds who will revere the newly-born dragon like the newly-born dragon did to their own heroes.

Bitter of the Past:
Kobolds miss the Age of Dragons. Nowadays they are a weak, spindly race - used more for digging sewers and mining than ruling over anything of merit. Those Kobolds that have been unable to find a stable profession, or who haven't turned to a live of adventure tend to be very bitter about no longer being a dominant race in Nevandaar.

Kobolds are submissive to Dragonborn, and outright fanatical toward Dragons, but to other races the little race is very condescending to. Seeing themselves as superior.
