The Chromatic Domains
The half-elves are equally mixed between human and elven societies. They tend toward the attributes of the race they grow up with. Their Color composition has an equal mix of Red and Green, and they have more Purple than humans. There are no great half-elf societies, and neither elves nor humans quite accept them as their own kin. Half-elves in history are known as individuals, and are rarely attributed to groups of either race. However, half-elves shine in collections of various races, and are often elected leaders of mixed groups.
The first half-elves were born in the same century that tieflings became distinct from humans; about 600 years ago. They live a little over twice as long as humans do on average.
