The Thirteen Tribes of Shizukesa: Tribes of Change

The gemstone tribes of Shizukesa are changing. Political upheaval and social discontent are the only things flourishing since the murders of the last Opal tribal members. No one knows this better than Miharu of the Aquamarine tribe, his twin brother, Masaru of the Ruby tribe, and their friends. With the tribes changing it is up to them to unify their society before chaos ensues.
