Abridged History of the 10th Age
A northerly race of amphibious folk, it is rare to see them south of Dorlan. They hate men, and follow rivers and streams to raid against menfolk. In the ancient rhyme known as the Banes of Man the lizard-folk are noted to be one of the terrible banes. This has led scholars to believe that they once raided as far south as Miles in the Second Age.
Lizard-men are divided into loose organizations that they refer to as tribes, and they speak a derivation of the Wyrmish Tongue. They are not extremely intelligent but have been known to develop ambush style tactics and to lay in wait for folks. Adventurers have been interested in repelling them for centuries, but they breed quickly and as soon as a single clan-nest is exterminated, another is founded somewhere else.
