Fairy Tail

Fairy Tail (妖精の尻尾, フェアリーテイル, Fearī Teiru) is the strongest Guild in the Kingdom of Fiore.The name of "Fairy Tail" represents a sense of adventure for one to be able to discover more about mysteries and fate.

History
It was said that the founder of Fairy Tail guild was a real Fairy.It is revealed that Fairy Tail guild was founded by Mavis Vermillion, Precht, Walrod Cken and an unnamed Mage in the year X686.The first Master of Fairy Tail was Mavis Vermilion. Mavis' grave is located on Fairy Tail's holy ground, Tenrou Island.

Fairy Tail has existed for at least several decades but has only grown to its current prominence and strength in the last few years. In this growth, it began to rival another large guild, Phantom Lord, and they began to be seen as symbols of the country.When the core members of Fairy Tail disappeared, the guild dropped to last place in strength,however, the core members returned seven years later.

S-Class Mage Promotion Trial
In the Fairy Tail Guild, the Trial (S-Class Mage Promotion Trial) is an event that is held every year, where the Master selects the most prominent members to participate in a trial in order to be promoted to S-Class Mages.Every year the trial is different and the venue also.Current S-Class Mages also take part in the Trial, to increase the difficulty of the task and make the Trial even harder to complete.

Fantasia
A parade held every year at The Harvest Festival where Fairy Tail Mages all display their Magic in a fantastical performance. The event is looked forward to not only by the members of Fairy Tail but by the whole population of Magnolia.

Leaving Fairy Tail
Whenever a Mage wishes to leave Fairy Tail, they are free to do so, however they are expected to follow three rules:
 * 1) You must never reveal sensitive information about Fairy Tail to others for as long as you live.
 * 2) You must never use former contacts met through your being in the guild for personal gain.
 * 3) Though our paths may have diverged, you must continue to live out your life with all your might, you must never consider your own life to be something insignificant, and you must never forget about your friends for as long as you live.

Strength
Ultear Milkovich stated that Fairy Tail is the strongest guild in Fiore. She also commented that Zeref's retrieval from Tenrou Island could be problematic as Fairy Tail's main members were currently situated there.Later, Lahar of the Magic Council notes that Fairy Tail is one of the three biggest protuberances of the Magic world, alongsideGrimoire Heart and Zeref.There are around 100 Mages in Fairy Tail.

During the S-Class Mage Promotion Trial all of Fairy Tail's most powerful members, including its Guild Master, disappeared. After that incident, Fairy Tail's strength dropped significantly until the disappearing Mages reappeared 7 years later. Even though the lesser members grew stronger,the loss of the core members still greatly affected Fairy Tail's strength, especially in comparison to guilds like Blue Pegasus and Lamia Scale, whose powers grew exponentially.

Members
In spite of the guild's immense reputation and fame, becoming a member of Fairy Tail requires little more than the simple approval of the Guild Master, regardless of Magical capabilities, former allegiances or the other members' opinion. This seems to be particularly true, as Makarov Dreyar had no troubles letting in Juvia Lockser, a former Mage of the Phantom Lord guild, which had started a Guild War with Fairy Tail and caused it great damage;Gajeel Redfox, another Mage from Phantom Lord who had badly injured Fairy Tail's Shadow Gear team and wreaked havoc on the guild's first building, was even invited into Fairy Tail by Makarov himself, with the Guild Master claiming that it was his duty to "guide young men who have lost their way back onto the right path".In year X784, Fairy Tail was composed by roughly 100 members.However, due to the events of Tenrou Island, the number of Mages was heavily reduced,remaining quite scant even following the return of many of the guild's top members from the island itself, ranking in few tens.

Mirajane Strauss, while talking to Lucy Heartfilia, explained that everyone in Fairy Tail carries the wounds of a sad past.
