Grimoire Heart was one of the top three Dark Guilds that the Balam Alliance was comprised of, as well as the one commonly considered the strongest Dark Guild. The guild owes its name to the Devil's Heart, an organic device which is the source of Guild Master, Hades' immense power, kept inside the guild's airship.

When Grimiore Heart first appeared in the story, their goal was to acquire all the keys rumored to be used to unlock Zeref's seal, as well as to locate the Black Wizard himself. Once these goals had been achieved, their intention was to use him, discovered in a slumbering state on Tenrou Island, to rule a world (referred to as the Ultimate Magic World) where the 90% of the world's Humans, those that cannot use Magic, would not be able to survive. Due to the Fairy Tail guild's presence on Tenrou Island when Grimoire Heart decided to make the move to unseal Zeref, one of its goals was also to get rid of "Fiore's #1 guild" in order to reach Zeref; a goal which, before finding all of the keys, they were also willing to leave to others, such as the fellow member of the Balam Alliance Oración Seis.


Main Article: Grimoire Heart Airship

Grimoire Heart doesn't seem to have any stable location. Its members live and travel on a giant airship that flies high above the land. Because of this, it is an elusive guild. Among other things, the airship housed the Devil's Heart, Master Hades' source of power.



As a member of the Balam Alliance, Grimoire Heart is acknowledged as one of the three most powerful Dark Guilds in Earth Land. Even among them, it was stated to be the strongest one by Levy McGarden, and one of the three greatest protuberances of the Magic world (alongside Fairy Tail and Zeref) by Lahar. Unlike the Oración Seis, Grimoire Heart has far more than six members, having several core members as well as numerous members of lesser rank. Many of its most prominent Mages have been shown to be incredibly powerful, and when they arrived to fight Fairy Tail on Tenrou Island they managed to battle and even defeat some of its top Mages. Its Guild Master, Hades, was able to defeat Makarov Dreyar, Fairy Tail's Master and one of the Ten Wizard Saints, with ease, and to similarly keep the upper hand over both Fairy Tail's Team Natsu and excommunicated S-Class Mage Laxus Dreyar, eventually being defeated by them just due to external intervention. The Deputy Commander of the guild, Bluenote Stinger, was able to fight on almost equal grounds with Gildarts Clive, Fairy Tail's Ace, and all members of its strongest team (the Seven Kin of Purgatory) have proven themselves to be of S-Class level strength. Azuma, in particular, even managed to combat powerful Fairy Tail's S-Class Mages the likes of Mirajane Strauss and Erza Scarlet on equal grounds. Even two "minor" members such as Yomazu and Kawazu, through their combined efforts, were shown keeping up with an S-Class level Mage like Gajeel Redfox for a certain amount of time.

However, after their defeat at Fairy Tail's hands, Grimoire Heart's strength lowered significantly: three of their top members, including Hades himself, were killed, one was turned into trees, and two (technically three, seeing as Caprico was being possessed by Zoldeo) of them defected from the guild.

Magic and EquipmentEdit


Grimoire Heart has one powerful spell associated with the Guild in which the Guild's founder created by reproducing a malefic version of one of Fairy Tail's great Magic spells, Fairy Law.
