Dark Opal

Born the heir to the House of Opal, Dark Opal conceived a passion for power early in his youth. After ascending to the throne of the House of Opal, he sealed pacts with various otherworldly forces, developed secret alliances, raised his mastery of his mystic powers to awesome levels, and awaited his moment.

When that moment came he struck suddenly and with all his power against the House of Amethyst and its allies, overcoming all resistance. Soon Dark Opal was master of the Gemworld.

For 20 years Dark Opal ruled Gemworld, seeking to consolidate his power in preparation for the conquest of other mystic realms. On several occasions he attempted to forge a breastplate containing silvers from each of the House Gems of the 12 royal Houses of Gemworld. This armor would increase his power to incredible levels, but each attempt was thwarted by Amethyst.

At last Dark Opal was overthrown by an alliance of the other 11 Houses, led by Amethyst. Caught in a mystic backlash as his powers imploded, the only trace of Dark Opal that remained was the clasp that held his cloak. This mystical trinket contained a sculpted face whose expressions mirrored Dark Opal's, and its frozen expression was one of madness and rage.
