The Last Days
With no known cultural identity to drive the race (at least not one that humanoid scholars know about), kobolds are a tough race to get a head around.
Small kobold tribes live in most mountainous or jungle regions, but few sizable populations exist. The largest population dwells in Shaarat Kol in Droaam. There are also large groups in Q’Barra and the Demon Wastes. Some believe that there is a large contingent on Argonnessen, as well, but with little support to back it up.
