Dungeons and Dragons: Krystallos
Lizardmen: Not all of Tiamat’s forces came from beyond the portal. Midway through the war the invaders captured an entire tribe of kobolds. Tiamat’s god-generals took special care in torturing and warping the poor kobolds until they were changed, body and soul, into monsters called lizardmen. The lizardmen are taller and stronger than kobolds but lack the cleverness or intelligence of their ancestors. Many were left behind when the war ended and they have taken up residence in swamps and caverns. Years of inbreeding due to their initially limited numbers have further reduced the intelligence of the lizardmen. Now, they are less intelligent beings and more mockeries of the noble people they once were.
