After Agon and Rynda were killed in a tragic accident, a new wise king started rulling Attilan. One day, when he and the two princes, Maximus and Black Bolt, were contemplating a new monument the Alpha Primitives were building, they were attacked with neural inhibitors and the king was rendered unconscious. The princes began fighting to protect the King and, after Black Bolt's voice blacked every attacker out, Maximus killed Dkamas, the leader of the Uprising.
Some time later, he stole the Slave Engine, his people's greatest weapon, along with the Xerogen Crystals it utilized and buried them somewhere in Tibet, for fear that it would corrupt his people and become a power too great for any Inhuman to wield. This led to a duel between himself and the heir to the throne, young Blackagar Boltagon who advocated the possession of the Slave Engine for Attilan's protection. Despite being by far the strongest of the Inhumans, moving the Slave Engine had weakened the Unspoken which led to his defeat at the hands of Blackagar and his friends. His final stipulation was that his deeds be remembered, but Black Bolt had a crueler fate in mind: the King, his deeds, and the Slave Engine itself, were written out of Inhuman history. From that day, he would be remembered only as a bogeyman to frighten small children. He would be...Unspoken.
