In the waring times of the 2nd era rose the Black king and his armies of the burned. They left in their path a scortch upon the earth which we know today as desert of trees. But at the edge of this desert lies the crag of two sins. A testament to the fallen armies of the Black king and his blighted armies. It was said that a lone knight chose to face the Black king with a blessed sword from his homeland. It was said to be a blade that brought life, not death. That from its edges poured forth the essence of God's love and devotion. It was this sword that severed the Black king's life from our plane, along with his armies turn to ash. On this sword enscribed were runic symbols, each a name for the Gods of our land that sought to oppose the Emporer of Fire.

It was this covenant that forged the strength to stand against the armies of scorn of blaze. To this day, when in battle, the natives will shout the name "SKIAL" to remember our triumph over The Ember King and our strength in our Gods and people.
That, Dr. Brule, is where the name skial comes from.
