Warriors All-Stars begins in a mysterious land brought to the brink of destruction when a magical spring, the source of its power, dries up after its king's passing. Following a legend that calls for the summoning of champions from other realms in times of dire need, the young princess Tamaki performs a ritual that goes horribly wrong when her powers spiral out of control, scattering the heroes across the domain. Emboldened to restore peace to the world, Tamaki must recruit the best and strongest among these visitors to revitalize the spring - and crown the land's savior as its new ruler.
