More than anything, kobolds are survivors. Their scaly skin and keen night vision as well as their dextrous claws and sensitive snouts make them quick to sense danger, and their clawed feet move them out of danger with cowardly speed. They are small but fierce when fighting on their own terms, and their weight of numbers helps them survive in places where larger but less numerous races can’t sustain a settlement. Kobolds are great miners, good gearsmiths, and modest alchemists, and they have a curiosity about the world that frequently gets them into trouble.
Underworld Merchants. Kobolds are merchants to both the surface world and the world beneath it, with their greatest cities hidden deep below the earth. Their enemies are the diabolical gnomes, the dwarves, and any other mining races that seek dominance of dark, rich territories.
Kobolds are closely allied with and related to dragonborn, drakes, and dragons. The kobold kings (and there are oh‑so‑many kobold kings, since no kobold ruler is satisfied with being merely a chieftain) admire dragons as the greatest sources of wisdom, power, and proper behavior.
