For unknown reasons, Arceus apparently shared its power with the people of Arche Valley for over 100 years, granting them mystical abilities. Baraz and Meray's great-grandfather Ghris was among the most proficient wielders of this power, which he used to create the Prison Bottle and contain much of Hoopa's power. His great-grandchildren inherited his ability, which they used in their efforts to help Hoopa and to contain the darkness contained in its former power. Later, when Hoopa's summonings of Legendary Pokémon through its rings created a time-space warp at Dahara Tower, Arceus intervened to keep the warp from collapsing until everyone was able to escape from inside of it. It then appeared briefly in the view of those it had saved before departing.
