Amalia is bitten by a poisonous Red Rose. Ruel says that his old friend, an Eniripsa named Nausica, lives nearby and can help heal her. They learn that the only cure to a Red Rose bite is sap from the rare Severum tree, which is located deep in the nearby Maleficent forest. Ruel and Yugo leave to gather the sap while Percedal and Eva stay behind to help care for Amalia. Not long after Ruel and Yugo leave, Amalia's doll goes berserk, attacking Nausea, Percedal, and Eva. It merges with Rubilax, turning into a monstrous demon. The trio overpower it, forcing Rubilax out and cutting the doll up into pieces, but the pieces turn into other dolls and attack in masses. In the forest, Ruel and Yugo are attacked by giant Venus flytraps, but are saved by a forest dweller named Sybannak. They are forced to help her in exchange for the sap, but when the tasks become tedious and monotonous, Ruel instead decides to steal some sap. Enraged, Sybannak attacks with the Venus flytrap monsters. Rue and Yugo escape with the sap and return to Nausea's where they save Amalia and return the dolls back to normal.

Following a very delicious smell, the group finds a man attacking a beast made entirely out of bread. They mistake the man for the attacker, only to later find out that the man, a innocent baker named Xav, was attacked by Breadnaughts who were after the rare Golden Wheat stored in his barn. Before the attack, Xav was going to enter a bread baking contest with the special wheat which is thought to produce exquisite bread. Wanting to fix their mistake, Yugo decides to help Xav make the bread while the others harvest the wheat. They enter the competition and with Yugo's help, Xav wins. The Breadnaught inadvertently reveals that she is Chouquette, Xav's father's former apprentice, and that she was after the wheat because she is in love with her master and wanted him to win.

The group is staying at Xav's place, and getting some tips on how to deal with Grufon from its original master, Gonnard the Great. A traveling herald passes though and tells the group that kamas (gold coins) are being stolen throughout the land. Ruel, afraid his own Kamas will be stolen, retreats into his magical bag, and uses a recall potion to return home. The others, Gonnard included, follow after him. They discover his home is built into a clay mesa and has a special code to keep intruders out and keep his stash of Kamas hidden. Gonnard reveals himself to be a shapeshifting genie that turns into whatever he eats, and as he eats kamas, he's as hard as gold. He overpowers the group and eats more kamas. Ruel, not one to give up his kamas, tricks him into eating chocolate coins instead. Gonnard eats them and turns into chocolate. Ruel traps him inside a glass vase and leaves Gonnard in his vault.

Upon arriving to the city of Bonta, Yugo & co. try to buy a boat to get them to Oma Island, but it's expensive. So Ruel enters them in gobbowl match, with his old team, Real Gobbly, against professional player Kriss Krass & his team, Lamechester United.

Ruel & his team, Real Gobbly, along with Percedal, play against opposing team, Lamechester United, led by professional gobbowl player, Kriss Krass.

When Real Gobbly is on the verge of losing, Ruel sends in Yugo, Amalia & Eva for one last effort to win the match and get the boat to Oma Island.

Having bought the boat with the kamas they earned in Bonta, Yugo and his friends go finally on the island of Oma. Only, it would seem that there is a stowaway on board of the ship, a passenger with willful intentions...

In the course of their trip at sea, the five friends encounter a terrible tempest and their boat is wrecked on an island. Yugo, Amalia and Evangelyne disembark in search of food, but primitive Sadida take them in hostage: these are Kaniboules! And it seems that they have the poor habit to give the foreigners in sacrifice in their godhead: big Moon... This smells bad for our heroes!

Amalia, Tristepin and Evangélyne wake up on a tiny islet. The boat was attacked by a mythical living being, Kralamoure Géant, and sank into the abyss. By way of islet, there is a huge and green island protected by an ancient fate of invisibility. The mysterious island of Oma where there should be the true family of Yugo.

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!

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!

Grougaloragram failed... Our friends have to be divided into two groups: on one hand, Ruel, Tristepin, Amalia and Evangelyne set off towards the kingdom Sadida to tell them about the threat which Nox represents, on the other Yugo and Adamaï which go looking for the Dofus in which Grougaloragran is going to reincarnate...

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...

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.

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.

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...

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.

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...

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.

Inside the temple, the Goddess Eliatrope welcomes her sons and their friends. Still exhausted from their recent fight with Oropo, the group decides to split up and return to the World of Twelve.

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.

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.
