Yugo meets the Eliatrope children and together they fight Qilby.

Nox and his troops land on the island. The Xélor attacks without deferring more from the purpose of his crusade: Wakfu contained in the Tree of Life. But the heart of the kingdom Sadida is protected by the colossal plant wall of the protective trees. Also the The Brotherhood of Tofu is in pursuit... Together, they well intend to hold the line.

Qilby tells Yugo his story and what he plans to do with the Eliacube while the other fight against Rushu.

Qilby shows his true face to Adamaï.

As Necros approach Albuera Island, Armand and Amalia are horrified to see the destruction that the creatures have wrought in their kingdom. But that's only the start of the troubles that Yugo and his friends will soon be drawn into. Elsewhere, the Sadlygrove family receives a most unusual visit.

Evangelyne takes the time to listen to Madagaskane, despite a bit of hesitation. Meanwhile, Yugo starts negotiations with the leaders of the World of Twelve to get their help against the Necros.

The line did not hold and final battle to protect the Tree of Life begins. Our heroes have a last trump: Yugo and his brother Adamaï entered the clock without Nox knowing with the crazy hope of taking over Eliacube, source of the power of the Xélor. Everything rests on their shoulders...

Yugo meets Phaeris, another dragon, who unlocks Yugo's true powers for his fight against Qilby.

Having hurt Evangelyne by employing from Rubilax in the Kingdom Sadida, our Iop finishes his escape in the desert and goes looking for the tomb of his ancient Master: Goultard. To his surprise, Goultard is not dead. Our Iop brain is going to discover how to become a true Shushu Guardian... He has to confront Rubilax and make him fear him.

The battle between the dragon Grougaloragran and Nox rages. Having been sent to the ice of the big North, Yugo and his friends wait for the end of this ultimate battle, feeling tension because it is the World of Twelve that is at stake!

As strange eyes appear over different regions of the World of Twelve, the Brotherhood of the Tofu moves through the devastated landscape of Ingloriom towards a temple bathed in an intriguing glow. They have no idea who they're about to meet in the ruins of this dimension, let alone the revelations that await Yugo in the only temple left standing.

Convinced that Qilby is involved in the appearance of the Necro portals, Yugo tries to confront him. He and his friends then travel to the Necroworld where they meet a powerful being with a thirst for Wakfu.

Yugo finds himself trapped in the Necroworld at the mercy of Toross Mordal, who has no qualms about subjecting him to various forms of vicious torture. Meanwhile, at the Eliatrope Temple, things take a rough turn for the rest of the group when Qilby disappears with the six Eliatrope Dofus.

Nora finds herself in a difficult spot as the fight between Qilby and Lokus continues in the Eliatrope Temple. Meanwhile, Yugo, still imprisoned by the Necros, is locked in a fierce battle with himself.

Back in the Sadida Kingdom, Amalia learns some tragic news. Meanwhile, Yugo is getting to know his sister a little better. Far across the World of Twelve, an old man continues his journey. And at the Stroud home, Ruel wakes up to a very unpleasant surprise.

The World of Twelve's leaders gather in response to recent events. Accompanied by his mother, Yugo tries to explain their reasoning to the assembled dignitaries. Unfortunately, his words don't have the desired effect. Meanwhile, a new threat draws closer to the Sadida Kingdom.

Yugo continues his exploration of the island of Oma with Adamaï, his brother dragon. During this time, by surveying the caverns, the companions discover the ruins of a very ancient temple kept by a terrible dragon! Stopping at nothing, the Grouilleux de Nox heads to the island!

Yugo and his brother Adamaï arrive on the famous island where Grougaloragran would have hidden the Dofus. Wanting to know about it more on his powers of Eliatrope, Yugo launches into a crossing of the Desert. But It would seem that the hunter of Nox, Igôle, has arrived on the island.

Yugo and Adamaï reach the goal of their trip finally: the secret shrine in which Grougaloragran hid his Dofus. There, they make the acquaintance of the guardian of the Dofus. But Igôle did not die, contrary to what our heroes thought...

The kingdom Sadida is on the brink of war, getting ready for the unavoidable attack of Nox. It is necessary to prevent the clock of Xélor from teleporting to the island at all costs. Amalia and Evangelyne wait without hoping too much for the return of their companions...

The Brotherhood of the Tofu and the demigods join forces to stop Oropo from killing the gods in a final battle that will decide the fate of the World of Twelve, and the universe. After a climatic battle, Oropo activates the Hyperzaap. In a last act of self-sacrifice, Echo uses her powers to send Yugo's group and the Demi-Gods though the Hyperzaap, leaving her and Oropo, who still loves her, to die as the Eliacube creates a massive black hole that destroys Oropo's dimension. Yugo and his friends find themselves in Inglorium, the realm of the gods.

Amalia and Yugo, confronted with a new wave of Necros in the Sadida Kingdom, try to repel the assault. Meanwhile, on Albuera Island, another attack is underway, led by an enormous Necro Dragon. The monsters are getting dangerously close to shore.

Since the departure of Amalia, the kingdom Sadida changed. The king is away and it is therefore Armand de Sheran Sharm, the brother of Amalia who governs the kingdom. During this time, Yugo and his brother Adamaï are still in search of the Dofus of Grouraloragran, but they do not know that Nox sent a formidable enemy in their wake...

The king Sadida is in the sanctum of the Tree of life, heart of the Kingdom Sadida which is mysteriously sick. Overstepping the ban of the prince Armand, Amalia and Evangelyne go to the King to tell it about the imminent attack of the Kingdom by Nox. But things do not turn out as they had envisaged it... During this time, Ruel searches a means to get away from the prison cell into which he was unfairly thrown...

When a large pandawa arrives at the door of Tristepin and Evangelyne in the middle of a snowstorm, the family's life is turned upside down. Yugo and Ruel continue to seek out Adamai who has been missing since the battle against Ogrest. In the Sadida kingdom, Amalia stands vigil at the side of her dying father when Yugo and Ruel arrive bearing bad news.
