In a distant past, Arceus saved the world by halting a catastrophic meteor's impact but was gravely wounded in the process. Grateful for Damos's care, Arceus granted the Jewel of Life to transform the barren Michina region. However, when the borrowed parts of Arceus were not returned, it vowed to judge humanity upon its return. Millennia later, Satoshi, Hikari, and Takeshi arrive at the serene Michina town, venturing to its ancient ruins atop a rocky summit. As they admire a beautiful lake, chaos ensues as waves surge and a water tornado emerges. Sheena, Damos's descendant, calls upon Dialga to quell the storm. Exploring the ruins, they learn of the ancient legend from Kevin and Sheena. But as Dialga, Palkia, and Giratina clash fiercely, the ruins crumble, heralding the awakening of Arceus.
