Highlights
Tartaros is the strongest dark guild in Fairy Tail and aims to revive E.N.D. and eliminate all magic in the continent.
Tartaros resides within a floating cube which functions as a formidable stronghold and a potent weapon in both defensive and offensive capacities.
The Nine Demon Gates, comprising influential individuals within Tartaros, present a considerable danger owing to their formidable capabilities for destruction and malevolent powers.
Fairy Tail is inhabited by a multitude of dark guilds that stretch across its villainous landscape, spreading corruption and fear throughout Fiore. The distinction between dark guilds and regular guilds lies in the recognition by the Magic Council, with the former operating without acknowledgement and defying the council's rules. Among these malevolent factions is Tartaros, a dark guild consisting solely of demons.
The members of Tartaros are known as Etherious, a term denoting beings belonging to the Books of Zeref. Given the guild's demonic composition, it is safe to assert that Tartaros is the most powerful dark guild in the entirety of Fairy Tail. With the sinister objective of resurrecting E.N.D. and eliminating all magic from the continent, Tartaros has solidified itself as the true driving force behind the Balam Alliance and a significant contributor to the series' antagonism.
The Purpose Behind Tartaros’ Formation
Tartaros was established by Mard Geer Tartaros, an immortal Etherious. During his long life, Mard Geer discovered the tome of E.N.D, Zeref's most powerful creation. Convinced that E.N.D. was imprisoned within the tome, Mard Geer formed a sinister guild and brought together Zeref's demonic creations. He declared E.N.D. as the guild's leader and promoted the idea of following E.N.D.'s will and bringing him back to life.
Mard Geer's plan involved using the Magic Council's weapon, 'Face,' which had the ability to eliminate all magic on the Ishgar continent. By eradicating magic completely, Tartaros could harness Curse Power, a type of magic used by demons, and utilize it to revive their sealed master. Once E.N.D. was resurrected, Tartaros would ultimately return to Zeref, even though this aspect of their scheme was a deception created by Mard Geer. In reality, he intended to kill Zeref.
The Guild’s Fortress: Cube
Tartaros' exact coordinates or the location of its headquarters have long eluded the Magic Council. The guild's unique base, a massive floating cube in constant motion, plays a role in this elusiveness. The inner workings of the Cube remain undisclosed, although it is speculated to be powered by Curse Power.
While primarily serving as Tartaros' primary defense, the Cube also possesses offensive capabilities. It can transform into a demon-like entity known as Plutogrim, unleashing sticky projectiles that ensnare any unfortunate human they come into contact with. These victims find themselves trapped in a state of permanent stasis. Fairy Tail nearly succumbed to Tartaros' might solely due to Plutogrim's sinister power. Fortunately, the Celestial Spirit King intervened, dispelling the spell and freeing the guild.
The Nine Demon Gates
Tartaros's power lies in its core members, known as the Nine Demon Gates. These Demon Gates, except for Silver Fullbuster, are all Etherious and are part of the Books of Zeref. Zeref refers to the guild as his "bookshelf" because each member is a creation from his foreboding books.
The Nine Demon Gates are the true source of Tartaros's power, as each Etherious is capable of defeating entire guilds and even nations on their own. Some of these demons stand out due to their destructive abilities, like Jackal who single-handedly eliminated the entire Magic Council. Silver Fullbuster is also renowned for his immense strength, demonstrated when he froze the entire Sun Village with his Ice Devil Slayer Magic.
Other members like Kyoka and Keyes also possess sinister abilities, with Keyes being capable of resurrecting the deceased through his adept knowledge of Necromancy. Seilah poses yet another significant threat as she wields the power to impose her will upon any object or individual, granting her absolute control over her target. However, the most formidable of all demons is Mard Geer Tartaros himself, who possesses the ability to invoke Memento Mori, a curse that ensnares its victim in everlasting darkness.
The Demise of Tartaros
The war between Fairy Tail and Tartaros served as a mere setup, overshadowing the initial confrontation against Mard Geer and the Nine Demon Gates. However, the true battle awaited as Acnologia clashed with the Dragons, steering the narrative in a different direction. As a result, Tartaros became an inconsequential name in the grand scheme of things.
The Fairy Tail guild emerged victorious over Mard Geer and the other demons, effectively dismantling the Balam Alliance by vanquishing its final member. Once the battle had calmed, Mirajane paid a visit to the dark guild's base and consumed the souls of each demon, assimilating them into her Takeover Magic repertoire. With their souls devoured, every trace of Tartaros came to a definitive end.
