The Articulate Plane
Aggressive, xenophobic, yet industrious small humanoid creatures, kobolds are noted for their skill at building traps and preparing ambushes. They are best known for their fervent worship of chromatic dragons and the goddess Tiamat.
Kobolds speak a version of the Draconic tongue, with a yipping accent. They are reptilian humanoids with ratlike tails, horns and hairless scaly skin. Their eyes glow red, and they can see accurately even in lightless conditions up to 60 feet away. Kobolds are described as smelling like a cross between damp dogs and stagnant water. Unlike dragons, kobolds are cold-blooded. Though they insist otherwise, they are more like lizards than dragons.
Kobolds are extremely fecund egg-layers, having the highest birth rate (and death rate) of all humanoid species. A female kobold will lay a clutch of hard-shelled eggs two weeks after fertilization; the eggs must be incubated for an additional 60 days before hatching. Kobolds reach maturity by the age of eight or nine and are considered “great wyrms” by the age of 121. They live up to 135 years. While they do bond with one another, they have no concept of monogamy.
Kobolds are found in all climates, although as cold-blooded beings they must eat up to three times as much in colder climates. They seem to prefer dark, damp underground lairs and overgrown forests. They are industrious miners and if left to their own devices can carve out massive tunnel complexes, which they rapidly fill to accommodate thanks to their rapid rate of reproduction – which would explain their reputation as cannon fodder to more civilized people.
Kobolds often guard their territory with ferocious animals which are either trained or chained into submission.
Kobolds have a scattered history, turning up in isolated regions with no apparent connection to one another. Even given the often nomadic nature of kobolds, divine agency is often evoked to explain how kobolds spread so far. Kobolds are thought to have begun their existence as the servants of dragons. They now continue to seek out (or attract) dragons for worship, though the dragon that pays any attention to a kobold is rare indeed.
