Seven Kin of Purgatory

The Seven Kin Of Purgatory (煉獄の七眷属 Rengoku no nana kenzoku) is the best team of Grimoire Heart Guild. It is formed from seven mages, each of them having unique abilities. These are the seven strongest fighters of Grimoire Heart under their guild master Hades and they are the most feared as well. Even Yomazu, a mage who critically injured Gajeel, said he was nothing before them and stood no chance of victory if he were to fight one of them. They are the main forces and the strongest formation of Grimoire Heart, which is correspondingly the strongest dark guild. This means that they are probably stronger than the Oracion Seis members.

Trivia

 * Purgatory is a reference to "the seven levels/terraces of purgatory" mentioned in the epic poem, La Divina Commedia (The Divine Comedy) by Dante Alighieri. In the poem, each level represented a different one of the Seven Deadly Sins and presented ways to atone for each sin before reaching paradise. It is possible that each member represents a sin. The sins are, in increasing order of purgery (in Dante's Purgatorio): Pride, Envy, Wrath, Sloth, Greed, Gluttony, and Lust, with Lust being the most forgivable and Pride being the most severe. Thus, it is possible the most powerful member represents Pride, while the weakest represents Lust.
