In Tyria there are two places Warforged come from. There are the standard issue Warforged that are usually sold to noblemen as servants. These Warforged are Factorum models and as they are granted free will usually escape or in worst cases turn on their masters. In most civilized areas a Warforged without a master is usually seen as a bad omen, and are usually wanted. The Factorum will put large bounties on any free Warforged. The second place Warforged come from is Dyssia’s Forge located in the Elemental Chaos, on a floating rock that is usually within 100 miles of the city of brass at any given time. These cousins of the Factorum models are know as Darkforged. They are often ancient and wander the planes aimlessly as their creator Dyssia had vanished from existence long before the time of the tear according to the legends.
Either kind of Warforged is careful to maintain a distance from civilization, however are sometimes hired on as bounty hunters or cheap labor. Often they are found riding with the Mountain Savages of Mahzoon or the Iron Wolf Marauders. However, Warforge have free will, and a free spirit that would rival the human thirst for life and individuality.
