Grimoire Heart

Grimoire Heart is one of the top three Dark Guilds that the Balam Alliance is 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.

Goals
When they first appeared in the storyline, Grimoire Heart's goal was to acquire all the keys supposed 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, wouldn't 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.

Location
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.

History
What is known of Grimoire Heart is that its founder and original Guild Master, Hades (real name Precht), was the Second Guild Master of Fairy Tail, and was made such by Fairy Tail's founder, Mavis Vermilion. In year X736, he bestowed the title of Third on Makarov Dreyar so that he could go on a journey. On this journey, Hades traced back the origins of Magic to Zeref, and saw what he referred to as the "essence of Magic". It is assumed that he turned "evil" after this point, and that he created Grimoire Heart and became its Guild Master in order to awaken Zeref and make The Ultimate Magic World real. Hades proceeded to gather young boys and girls with strong Magic potential, such as Ultear Milkovich, and spent years raising and training them for them to become the Seven Kin of Purgatory, some of the greatest Mages under his command, who use Magic that is as close as possible to the source of all Magic, taught them by Hades himself: Lost Magic.
