Age of the Dragons
The most common of the races of men is the namesake – humankind. Humans come in all ethnic varieties as on Earth.
Humans are also able to breed with the other races producing “half-breeds”. They appear primarily human, but generally have physical appearances that hint (usually more obvious than not) to their heritage. In nearly every society on the planet, this is viewed in a negative light – racial integration in society is not frowned upon, but integration in body is. The racism is usually projected onto the halfbreeds themselves, rather than the parents.
