Before everything, there was only Chaos. A Cosmic Egg surrounded by the five elements — Wood, Fire, Water, Earth, and Metal — held Yin and Yang within it, ready to merge and create the first human and the first universe. Chaos shattered the Egg rather than allow that change and hurled Yin and Yang as far apart as possible. They landed in the Land of Wood. Now they must cross all five elemental realms, find their Guardians, and reach the Egg again before it ceases to exist entirely.
