November 30th. The day all constellations should remember. The day a strange power came to the 13th dimension known as Astrolia. Everything has become shifted and unbalanced due to how strong this power is, yet it comes from such a small source. No one knows what to do with it, not even the King.
No one predicted that this would happen. And no one thought that anyone would try to steal this power. But trouble starts to brew in Astrolia, when an evil ridden being that calls himself Hydrus, appears before Orion's throne, claiming that he shall be the new King of Astrolia.
With Orion now gone from the throne, the memories of all Astrolians have been strangely altered, causing them to believe that Hydrus is now their new ruler, and the 12 zodiacs are outlaws.
With the whole city of Astrolia against them, the zodiacs are sent down to earth by the queen herself, in order to find a certain item that will help them. But as their journey continues, their memories soon start become altered by Hydrus's Black Magic, causing them to start thinking irrationally and delay their mission.
The only chance they have to save themselves and their home, is to unlock the power within their pendants, and to keep themselves from forgetting what's important.
The fate of the world depends on them.
