Seven Princes

Seven Princes (セブンプリンセス, 7 Ōji) is an order of the "Seven Princes of Hell". Each prince is cursed with a sin they must bear for eternity.

History
During the creation of Earth Land, Heaven and Hell imprinted the earth with their Magic. While Heaven brought purify magic and Celestial Mages, Hell took the shape of an ultimate demon, Doa Gelap, whom was crowned King of Hell. He created his "Seven Sons" to do his bidding out of the Black Arts he was made of. The Seven Princes were each given a portion of Earth Land to terrorize. Before Doa Gelap could create Hell on Earth Land, he was overpowered by a strong Angel of Heaven whom defeated him using The One Magic. The Seven Princes, without their father to lead them, hid in the different dimensions, but left their demons dormant in Earth Land so they may rise again when the time is right.

After the battle between and, the dark energy seeped into Earth Land and woke up the dormant demons whom made up Goetia Eye. Once all seventy-two demons were defeated, the Seven Princes returned to Earth Land to find their scattered Golden Trumpets and wake their father once again.

Location
The Seven Princes do not appear to have a set location. Each member travels separately and live in their own dimensions as they watch over their demons.

Goal
When the Seven Princes were created, the goal all seven commonly shared was to spread their sins across the world in order to achieve Hell, so to speak. They created demon servants to do their bidding and wreak havoc. They were to prepare the world for the arrival of their Master, Doa Gelap, as well as their father.

Strength
Individually, each member of the guild is able to destroy a portion of Earth Land with their Sin Black Arts alone. However, combined, the members are quite capable to destroy Earth Land, but not enough to recreate Hell on Earth Land. With their master Doa Gelap, they can created Hell once more.

Magic & Equipment
There is only one magic type that the whole guild revolves around.

Sin Black Magic: User can sense and manipulate the sins and vices of themselves and others, whether increasing, decreasing, causing or otherwise chancing envy, even manifesting the emotional energy to physical level. The user can as well detect where the sin is in a person as well.

Golden Trumpet: Only the Seven Princes were each gift with a Golden Trumpet. Individually, each trumpet can call upon the demons of the Prince. But combined in song, the trumpets have the power to resurrect Doa Gelap from his thousand year slumber.
