The Svirfnebli armies had been massing secretly for many years at this point. The Svirfnebli have almost as long a lifespan as dwarves and they spent most of the time up to this point keeping their true power secret and dominating dwarven nobles to aid them in the coming war. Dwarves however were not as susceptible to psychic powers as the warlords hoped and they spent many years on only a few individuals.
When they did attack it was a powerful assault, They began systematically defeating the strongest resistance in the area and worked their way toward the dwarves. The peoples of Golthorian and the surrounding regain had been suspicious for a long time but nothing could prepare them for the onslaught. They employed fierce warriors with enhanced weaponry and armor along with their Psions themselves. They also kept a variety of terrible beasts in their employ such as corrupt xorn and phase spider mounts.
