The Obsidian Crown
The power of Thraek pulsates within inky blackness of the jewel like fire in darkness. While the origin of the diamonds is unknown, they are known to focus their arcane abilities of Thraess. The focus provided by the diamond eliminates the mental fatigue of maintaining spells. Many Thraess have their El’ildar diamonds crafted into their swords, staffs or jewelry.
Those not elevated to the Thraess appear to be unaffected by the pulsating diamond. However, folklore says that anyone in possession of an El’ildar diamond will promoted to positions of power and can easily influence others decisions.
