Half-dragons are incapable of having natural born offspring. Those that wish to propagate must find other ways to do so, almost always involving magic. By way of compensation, half-dragons are blessed with long life. Barring unforeseen misfortune, a typical half-dragon’s life expectancy is twice that of its nondraconic line, so that a half-dragon human might live more than a century and a half.

Half-dragons inherit personality traits common to their draconic heritage, so that half-gold dragons are often shy and secretive, while half-copper dragons are impish and playful. Half-green dragons are deceitful, while half-white dragons are often dim-witted brutes. These traits are tempered by a half-dragon’s other lineage, but greed, arrogance, and paranoia are qualities that even good-aligned half-dragons often possess.

Humans vary widely in height and build, from 6 feet to over 7 feet tall. Regardless of your position in that range, your size is Medium.

You can speak, read, and write Common and one extra language of your choice. Humans typically learn the languages of other peoples they deal with, including obscure dialects. They are fond of sprinkling their speech with words borrowed from other tongues: Orc curses, Elvish musical expressions, Dwarvish military phrases, and so on.
