Long ago, she had been a beautiful Topaz. With a fierce, fiery temper and a desire to protect her friends, she was adored by many gems. But then, it happened. The virus.

The virus was the only known virus that could infect gems. Very few ever survived. There was no cure, and there had been no previous cases of complete recovery, but that didn't mean it couldn't happen. The Obsidian Virus attacked the gem directly, either driving the gem insane, or massively affecting the personality, turning them very cruel and evil, and erasing their memories and their ability for mercy. Topaz had been the latter. But that's not all the virus did to you. It started turning your gem black. And your tears became black acid, as well as any blood you gave off. Most likely, your gem would eventually crack and you would die. But not Topaz.

Her gem had turned completely black, and it seemed as if it would crack. But it didn't. She was almost insane, and about to kill her best friend, Spinel. "Please, this isn't you, Topaz!" she begged. Topaz, with wide eyes and a crazy grin, only laughed. "There is no more Topaz," she hissed. "I am Obsidian!"

And so began the wrath of Obsidian, the tainted gem, who was once beautiful and protective, now a wild, bloodthirsty, maniac who gave no mercy and lived only to kill.

But don't think that's all. Tainted she may have been, something struggled within her to find its way out. To restore her to what she used to be. For a long time, it never managed to escape. But one day, things started to change. And Topaz began to resurface, little by little.
