Dawn of the Gods
The history of the Warforged can be traced back roughly 600 years to just after the first Godswar. The appeared in the lands just south of what are now the Dead woods. Many stayed in that land but others expanded and explored.
No Warfored has memory of before coming out of the mountains. Though they had engineering and manufacturing knowledge far surpassing those they settled with they had no memory of themselves as a people.
Warforged are rare but welcome members of most societies. Their natural traits make them ideal laborers and artisans. Though there are many people who think them unnatural and not to be trusted.
Warforged live to be well over 300 before their “light goes out”. Reproduction occurs between any two Warforged and after coupling one or both of the participants develops a small metal sphere called a kernal. This kernal will grow over the course of two years before developing into a Warforged child. Newly “hatched” Forged are capable of basic speech and reasoning (comparable to a human toddler) and will develop into an adult Forged in about 6 years.
