A magician attempts to use the power of the Millennium Comet to awaken the legendary Pokémon Groudon.

The heroes, who are thirsty, wander the land. Brock shows them a spring, but it ran out of water. They go to the village, but find it deserted. Just as Lotad falls in a well and gets risen up, it evolves into a Lombre. Much to the heroes' surprise, the villagers start coming out of their houses and pray to Lombre and start cursing a Solrock, believing it is the reason for the local drought. In order to prove them wrong, the heroes decide to investigate.
