Only to had the power needed to restore balance against Yveltal's destructive nature and restored life to both humans and Pokémon of Kalos. Diamond Domain was the state owned by Diancie. The life of state depended upon the Heart Diamond created by Diancie itself. Many unevolved Carbink lived at the Diamond Domain.

However, Diancie soon became powerless as the time passed and thus the Heart Diamond. The energy of Diamond continued to low. Diancie now moved to search the source for the energy to energize the Heart Diamond and met Ash and the co. They decided to help her by making their way to Xerneas, the giver of life and the energy.

During their Route, they got attacked by two thieves and Team Rocket who wanted to capture Diancie. They got rescued by a young girl and her dad. Continuing their journey, they battled the Pokémon of destruction, Yveltal.
