Jahan and Yasmin were "born" at Wetson Incorporated—located in Sacramento, California—on June 18, 2129, as part of a genetic engineering experiment. Prior to their "births", scientists had tampered with their DNA and developing brains, giving them "Beat-Sonic"—the ability to manipulate sound waves with their minds and hands.
They were raised by the organization—who hoped they could be used as weapons to take down the current world leaders (though the sisters didn't know this)—for several years. At age 11, however, they were smuggled out of the lab by Dr. Kristin Spectrus, a rogue Wetson scientist who opposed the organization's plans. Spectrus was killed escaping, though Yasmin and Jahan managed to save themselves by getting lost in a forest. In the forest, they met Mina Downer—leader of the Hardplayers—who, after some debate and consensus, allowed them to join her.
The Hardplayers went undiscovered for six years...then everything changed after Mina was kidnapped.
