Makes sense for a land with primitive lizard folk. Could make for a nice consistent antagonist from beginning to end of a campaign or a campaign twist with slight changes. I did something similar with Orcs. My players kept wading through Orcs like a hot knife through butter so I had them united under one Chieftain and gave them few levels in fighter and one level in barbarian depending on EL, except for the elite Orcs of the clan who are full barbarian (3.0). There first encountered after the unification of the clans was a surprise to them. Took time to setup but was worth the wait. Go to Comment
Khor are a monsterous and violent race. Within five years of being born, they grow to about half human size and are very, very inteligent. As they get older, they get larger... unfortunately they become less intelligent. After their adolecesence (about seven years), they grow to human size and are of a low human intelligence. As they age, they grow larger, slower, and stupider. Most of them end their lives 3 to 4 meters in height. Khor have been reported upto 10 meters tall, though those elder giant Khor do little but hit anything that disturbs them.
As they age they get larger, they don't seem to ever die of natural causes.
