Archdemon is one of the Old Gods manifested in a form of powerful dragon, tainted by darkspawn. It is far more intelligent than an average dragon and it is purely evil creature. Under the surface darkspawn search for the sleeping Old Gods and when they find on of ancient dragons, it is immediately afficted by the taint. He becomes their leader and gather them and unites into a great horde to unleash it to the surface. Normally darkspawn are organized as a simple hive mind and move only as the horde. Yet from time to time they appear on the surface to raid and during small invasions. Just like darkspawn, Archdemon seldom fights on the surface during Blights. This dragon leaves underground only when direct intervention is needed. It also possesses power to communicates and commands his entire horde and often sends his orders to emissaries or mighty hurlock generals. The horde destroys and leaves in ruins everything on it’s way and the only way to stop it is to kill Archdemon. Grey Wardens frequently see and hear Archdemon in their dreams and some of the veterans even claim that they are able to understand the dragon’s speech.
