Gremory Clan

"Family. Duty. Honor."

- Gremory Clan's house words

The Gremory Clan is one of the remaining 32 pureblood houses of the 72 Pillars. They are among the high-ranking houses, ranked at the fifty-sixth of the hexagram, and hold the title of [Duke].

Summary
As the house that produced the Super Devil and current "Lucifer", members of the Gremory Clan are characterized by their crimson-colored hair and their immense amount of demonic power. However, despite being one of the elite 72 Pillars, they are known for their extraordinary affection among other devils, and as such, they do not discriminate themselves with their servants or the smallfolk within their territory.

The house was founded by the original Gremory, who was one of the demons who fought alongside the original Lucifer during the Heavenly War. He is also one of the few who escaped imprisonment within the Underworld because of the Ouroboros Barrier and had passed down his title of [Duke] to the cardinal devil he created, Medgar Gremory, to enter "retirement" and the noble house of Gremory started from then.

The family isn't known for scandalous reputation or outlandish tales, though members of the house are known for being the inspirations behind some of the Netherworld's most beloved romances, such as the tragic love between Elston Gremory and Vespair Lucifer, or the elopement of Zeoticus Gremory and Venelana Bael.

During the Devil Civil War, they were one of the main supporters of the Anti-Satan Faction, with the faction's leader, Sirzechs Gremory, being the family's heir and only child. After the war ended victoriously in the rebellion's favor, the Gremory Clan claimed the territory of the Lucifer Clan for their own. Sirzechs was then crowned the new "Lucifer" and abdicated his title as heir to the Gremory Clan, passing down the position to his younger siblings.

Following the creation of the Evil Pieces, they became known for "collecting" famous historical figures as their servants, such as Heinrich Cornelius Agrippa, Souji Okita, or MacGregor Mathers just to name a few, as well as the descendants of mythological figures such as Beowulf or the Giant King Surtr.

Newer servants of their peerages have also shown to possess tremendous growth and potential, the most obvious example is that of Issei Hyoudou - Pawn and fiancé of the house's heiress Rias Gremory, the current wielder of the Longinus Boosted Gear, a potential Super Devil and a possible candidate for the future title of Satan Asmodeus.

Traits
Members of the Gremory Clan are known for their fair skin, crimson-colored hair, and blue eyes in a variety of shades. Male members of the house are also known for their androgyneous looks, which they would eventually grow out of in their mid-300s.

Hereditary Ability
Like other pureblood devil houses, members of the Gremory Clan possess a unique hereditary power called the Eye of Providence. This hereditary ability grants its user a wide range of magical abilities which they can utilize using their eyes as a focus point to perform them without the usage of a magic circle, in addition to lessen the required amount of demonic power. An additional power they possess is the power to perfectly control their demonic power, which allows them to control the range, effects, and overall power of any technique they perform.

Due to Venelana Bael's marriage to Zeoticus Gremory, her children, Sirzechs and Rias, as well as Sirzechs' son Millicas, all shown to possess the Bael Clan's hereditary ability called Power of Destruction much like their Bael cousins, though their mastery is at a much higher degree of mastery to the point where the devil smallfolk have begun to associate the power with the Gremory Clan as well.

Cadet House
According to Rias, the Gremory Clan used to have several cadet houses living across the Gremory territory. However, they were all killed by the Old Satan Faction during the Devil Civil War as revenge for Sirzechs' rebellion.

Emblem
The Gremory Clan's emblem is a stylized rose encased in a circular shape and is crimson in color, often placed upon a black background. This emblem, however, isn't typically used on their banners, but instead a stylized golden sigil of a horned camel wearing a duchess' crown with a garlan of red roses around its neck is used.

Residence
The Gremory Castle ( グレモリー城, Guremorī-jō ) is the seat of the Gremory Clan located in the northern region of the Gremory territory. It consists of the Tower of the Sun and the Spear Tower, as well as a feast hall and a solar for the Gremory family which are connected by a long gallery with a rough-cut stone floor. The castle is located on a cliff overlooking the Boiling Sea, called the Elenei Cliff because of the tragedy happened there.

The Tower of the Sun has a dome of gold and stained glass, beneath the dome sits the throne room which is a large round room with thick windows and many colored glass, with floors made out of pale marble. Within the throne room there are two seats on a dais, near twins to one another, with the only difference being that one is inlaid with the Gremory Clan's rose emblem on its back and the other features the Lucifer Clan's morning star.

The Spear Tower is a massive tower of white marble that thrusts up from the surrounding buildings with a spear of gilded Chthonian steel atop. Highborn prisoners and political hostages can be confined in cells at the top of the Spear Tower.

Ruby Castle
The Ruby Castle ( ルビー城, Rubī-jō ) is an ancestral palace built by Medgar Gremory to use as a palace for his hundreds of concubines and thousands of offsprings. As shown with Zeoticus, bastards of Gremory lineage are also raised and trained in the Ruby Castle until they reach adulthood. It is tradition for the newly-wedded Gremorys to spend their wedding night in the Ruby Castle.

Ruins of Connection
The Ruins of Connection ( 接続の廃墟, Setsuzoku no Haikyo ) is a ruin located north of the Gremory Castle, deep inside a great forest of trees with white-bark and blood-red leaves. The place was originally a church built by Prentys Gremory for his unnamed human wife, who was recorded to be a devoted Christian and had never known about her husband's true identity until her death, after which Prentys committed suicide. Since then, it has been a tradition where a Gremory confesses their true feelings to their partner and marries them there.

Gremory Large Enterprise
The Gremory Large Enterprise ( グレモリー大企業, Guremorī dai Kigyō ) is a business enterprise owned by the Gremory Clan which operates various business ventures in the Netherworld as well as the mortal world. In the mortal world, the Gremory Large Enterprise operates several travel agencies and five-stars hotels in various countries and large cities all across the world, though in recent years, they have also been involved in the film industry. The current president of the enterprise is Zeoticus Gremory; the current head of the Gremory Clan.

Members of the Gremory Clan's peerages are able to receive a job at one of the companies owned by the Gremory Large Enterprise, and the rewards for their summoned jobs are also treated as part of the enterprise's ventures. High-ranked peerage members such as Issei or members of Zeoticus' and Venelana's peerages are also made branch managers of one of the enterprise's numerous subsidiary companies.

Oppai Dragon
The Breast Dragon Emperor Oppai Dragon ( 乳龍帝おっぱいドラゴン Chichiryūtei Oppai Doragon ), also known as the Oppai Dragon for short, is a tokusatsu show in the Netherworld, which follows the adventurers of the titular character (based on Issei Hyoudou) and his partner, the Switch Princess (based on Rias Gremory). The show is noted to be very popular not only among the children but also teens and young adults because of its dark humor and has a high viewership, exceeding 50% upon its initial showing. Due to the popularity of the show, it is noted to be a great source of revenue for the Gremory Clan.
