Valen created the relic so he could alter the universe in his own image, but he was destroyed in the process. The relic was then sealed so that no one could use such power for their own selfish ambitions. The East Heaven Kingdom was entrusted to keep such a dangerous relic from anyone who wished to use it.

In their quest, both Mint and Rue search for the relic so they can use it for different reasons. Mint wants to use the Dewprism for world domination, while Rue wants to use its powers to resurrect Claire.

Yet another person seeking the relic's power is Doll Master, who wants to resurrect his master, Valen, so he could finish his mission.
