In the darkspawn armies, the few toughest and most intelligent of the darkspawn become alphas, the commanders and generals of the darkspawn armies. Of these alphas, a few become Emissaries, the spellcasters of the darkspawn with abilities similar to Blood Magic. However, these emissaries rarely appear outside of a Blight, when they appear to see to that the generals and commanders of the darkspawn armies serve the archdemon's interests and not their own.The Emissaries are the only ones among the darkspawn that have been known to possess the ability to speak and communicate to other species, though topics of discussion with non-darkspawn races are rather limited.
