Once, Noximilien was an ordinary clock maker with a loving wife and 3 beautiful children who has a lot of debt and a very nosy debt collector. One day, while showing his family a new invention, the family dog Igol goes missing, having run into a cave. Noximilien chases after him and falls into a cavern with a glowing pond. The glow is coming from a mysterious cube; the Eliacube. He leaves it behind at the behest of his wife, but his mind cannot leave it alone. He goes back and takes it. He spends the next few months studying it, trying to crack its secrets, ignoring his family. His research turns into obsession; his body begins to wither from malnutrition, his movements become more erratic, and his mind becomes unstable. One day, his wife leaves him, taking the children with her to stay with her sisters on an island offshore. Believing he made a mistake, Noximilien tries to leave, but the allure of the Eliacube was too much.

It's already six years after our heroes saved the World of Twelve from Qilby. They've all taken the opportunity to settle down into a peaceful existence. None could imagine what awaits them.

A strange messenger has come to inform Yugo, Adamai, Ruel, and then Percedal's family, that Princess Amalia, needs them : Ogrest is having another crying fit, which is flooding a huge part of the Sadida Kingdom. Worse still, the six Eliatrope Dofus, the only things capable of stopping him, have gone missing!

Only two of the precious eggs have been located: they're being held by the odious Count Harebourg, lord of Frigost Island. He's agreed to give them back in exchange for Amalia's hand in marriage. Ready to do anything to save her people, Amalia accepts his offer and the entire Brotherhood accompanies her to Frigost.

In this 2nd episode, our heroes held captive in Harebourg's icy prison, discover Joris, Kerub, and Atcham trapped in blocks of ice. Once freed, the prisoners explain how they came into possession of the six Eliatrope Dofus, and how they lost them.

The members of a mysterious brotherhood, the Forgotten Fraternity, took them. To what end? No one seems to know. But t they've worked since the beginning of time to write history as they want it written...

While Otomai and Adamai continue their quest for Dofus in the Kingdom of the Winds, Yugo joins Joris, Atcham and Kerub to explore the Ecaflip Dimension. Amalia, Ruel, Percedal and his family go back to the Sadida Kingdom to save it from the waters...

In this last Episode, getting back to the Sadida Kingdom, Yugo discovers that Percedal has decided to directly attack the root cause of the problem: the terrifying Ogrest. The Iop warrior has gone to Mount Zinit. To Yugo, it's obvious they must go help him, no matter the cost.

But strangely, his brother, Adamai, doesn't agree. Did his visit to the Kingdom of the Winds disturb him? No matter! It's time for actions, not questions! Yugo has made his decision : he'll go help Percedal, with or without Adamai! The destiny of the World of Twelve is in our heroes' hands, now more than ever.

Drawn to the power of the Eliacube, Oropo and his siblings make their way to Oma Island to face off against Grougaloragran and claim the device for themselves.
