"Every beginning has an end" -Santosh Kalwar
1000 years ago, a dark creature by the name of Nomed attacked Fairy World with the intent of draining all the fairies of their magic. But, thanks to Cosmo's stupidity and clumsiness, Nomed was was distracted enough for him to be sealed away by an ancient group of fairies, known as the Fairy Sages.
A millennium later, he broke free from the seal and absorbed the magic contained in The Big Wand, the source of all Fairy Magic. Meanwhile, Timmy Turner and his Fairy GodParents, Cosmo and Wanda, were in another dimension spending Halloween with Lincoln Loud and his best friend, Clyde McBride. They were eventually confronted by Nomed who intended to turn them and everyone else on Earth into his monstrous slaves.
They escaped to the Loud House but were quickly tracked down by Nomed, who then proceeded to turn Lincoln's parents, Bobby and Clyde into monsters. With nowhere else to run, Timmy had Wanda use her emergency wand to poof them, Lincoln and his sisters to Fairy World. Once there, they were tasked with finding the Fairy Sages to help them defeat Nomed and save Royal Woods.
They were able to find the Fairy Sages, but learned that the Fairy Sages were unable to help them and instead bestowed upon them their magical powers and The Sage Wand.
Timmy, Cosmo and Wanda and the Loud Siblings returned to Royal Woods and after a fierce battle, Timmy was able to use the Sage Wand on Nomed. The magic Nomed stole returned to The Big Wand, giving the Fairies their magic back and returning everyone back to normal. The Fairy Sages then wiped everyone's memories, except for Timmy's and his Fairies, and stripped every one of their powers, returning everything to the way it should be. But that was not the end of their problems…
Months later, Timmy attempted to find a date to the Valentine's dance, but no one (barring Tootie) wanted to go with him. Tired of no one giving him a chance, Timmy expressed his feelings of no one loving him to Chloe and left school in a huff. Feeling sorry for him, Chloe wished that Timmy could have the Perfect Girlfriend. Timmy, unaware of Chloe's wish, met a girl named Isabella and was instantly smitten.
The two grew close, but the happiness didn't last as a mysterious cloaked figure named Vrej arrived with The Staff of Mischievous Magic, a staff with the power to rewrite wishes, cancel them or erase them from existence. Using the staff, Vrej rewrote Isabella and had her lead Timmy and Chloe into a trap where he revealed to Timmy Isabella's true nature and announced his desire to make Timmy and the Loud Siblings suffer. Vrej then poofed himself and Isabella's to their school while Timmy was discouraged by the true nature of Isabella. Chloe and eventually Cosmo and Wanda talked Timmy out of his funk and they headed to the school.
Timmy was able to retrieve the staff from the Vrej and fixed the damage that was done to Isabella. Unfortunately, Vrej regained the staff and erased Isabella from existence leading Timmy to attack him in a fit of rage. Timmy once again retrieved the staff and Vrej was forced to retreat. Soon after, Jorgen recovered the staff and erased everyone's memory so they wouldn't remember what happened that night. But Timmy remembered, and the event had left scars that will take time to recover from.
Sometime later, Lisa had discovered breaches in the fabric of space originating in her neighborhood and started to search for the reason why. After reviewing all the data she had acquired, she discovered that every time a breach in space occurred, it was around the time Timmy visited her home. Intent on proving the existence of other Earths, Lisa started to work on a new project.
Days later, Lisa unveiled a machine that would allow passage to other Earths, but it soon malfunctioned and flung Lincoln to the underwater world of Bikini Bottom. There he met SpongeBob SquarePants and Sandy Cheeks who both vowed to help Lincoln find his way back home. To do so, Sandy required an item from her pen pal Gadget and sent SpongeBob and Lincoln to get it while she worked on the rest of the device. After a few obstacles and a warning from Vrej's sister, Malie, Lincoln and SpongeBob met Gadget, who revealed that she was really Sandy's cousin, and gave them the item they needed.
Everything was going Lincoln's way until Vrej appeared and revealed that he had kidnapped his sisters and taken over Neptune's Castle, forcing Lincoln and SpongeBob to stage a rescue. With Sandy's help, they traveled to Neptune's Castle and fought Vrej. The fight ended with Lucy freeing the captured Neptune, who used his trident to destroy Vrej. Soon after, the Fairy Sages restored the Loud Siblings memories of what really happened on Halloween night and sent them back home.
But things didn't end there. One day, Lincoln woke up to find his sisters acting differently than usual and tried to find out why. After a while, he decided to accept the change until Vrej appeared before him, alive and well. He revealed that Lincoln was in an illusion and pulled him out of it, just in time for Malie reveal that their mother, Maya, was to blame.
Later that night, Lincoln revealed to SpongeBob and Timmy that Maya severely damaged his house, costing the Louds' vacation fund, but SpongeBob suggested that they come to Bikini Bottom for the annual summer festival, which he agreed to.
Maya later turned her attention to Timmy as the 10-year old tried to get into Trixie Tang's annual summer pool party. After many attempts to get an invite, Trixie personally gave him one and he spent the rest of the party trying to impress her. After many failed attempts, he unwittingly gained her attention due to their shared love of comics. The moment was soon ruined when Maya appeared and infected Timmy before disappearing. Malie soon appeared and apparently cured him, but a slight change in his eye color proved otherwise.
Meanwhile, in Bikini Bottom, a government official, named S.F., bought out Bikini Bottom and announced that he would cancel the summer festival and demolish the city. In order to save Bikini Bottom, SpongeBob embarked on a quest with the Flying Dutchman to find the tear of the legendary sea god, SB, the only treasure that would allow him to buy it back. Despite his many obstacles, SpongeBob obtained the tear and traded it to S.F. for Bikini Bottom. But that was exactly what S.F. wanted and now he's almost ready to conquer Bikini Bottom as Timmy and the Loud Siblings prepare for a kids only vacation in Bikini Bottom.
