From Ardrana

Kobolds are a cowardly, sadistic race of short humanoids that vigorously contest the Human and demi-Human races for living space and food. They especially dislike Gnomes and attack them on sight.

Barely clearing 3 feet in height, kobolds have scaly hides that range from dark, rusty brown to a rusty black. They smell of damp dogs and stagnant water. Their eyes glow like a bright red spark and they have two small horns ranging from tan to white. Because of the kobolds' fondness for wearing raggedy garb of red and orange, their non-prehensile rat-like tails, and their language (which sounds like small dogs yapping), these fell creatures are often not taken seriously. This is often a fatal mistake, for what they lack in size and strength they make up in ferocity and tenacity.

Kobolds speak their own language; many also speak the tongues of orcs and goblins.

Note: Kobolds originally appeared in this form in the 2nd Edition Monstrous Manual for the AD&D game from TSR. Their use here is for the purposes of providing context for the campaign only.
