The legendary sword of power
The Runesword was given to Theo during the Great War by an Elven king who deceived him into thinking it would help stop the Dragonlords, when actually it dominated his will and caused him to attack the Grey empire. It is said to have been retrieved by Piffle the Fool after it fell from Theo’s hands, who was too insane for the sword to effect him.
The sword was locked away in a thick vault beneath the castle at Karas, where it could not be found by anyone and used against the Emperor.
