The Free City of Mittburg in the Grenwal Confederate Empire is considered one of the biggest success stories of how Kobolds and other races can live in peace. Originally built by humans, hundreds of years ago the inhabitants of the city found and recruited a den of Kobolds that lived in the cave system underneath. Today, the Kobolds of Mittburg developed a unique culture, taking on the worship of Bahamut and other deities, and seemingly occupying the niche that dwarves and gnomes normally take as craftsmen. It's said that, in current generations, the scales of the Kobolds of Mittburg are taking on a more metallic sheen...
In more recent times, there seems to have been a strengthening in the concentration of draconic blood within kobold tribes, making it so that many kobolds are now considered a type of dragon instead of a humanoid. However, as notable as they are, these developments have been slow.
Kobolds of Sancstoryl reach maturity at age 6 are able to live around between 150 and 200 years old, longer than most worlds on the material plane, but usually die way earlier due to being quite fragile little buggers.
