Seven Great Satans (Dragons of the Apocalypse)

"History is written by the victors I guess"

- Nicholas Satan The Seven Great Satans also known as the New Satan Faction or the New Devil Society is a term which refers to the Seven Satan System created by Cyrus Paimon, Zekram Bael, and Arie Mammon during the disaster that followed the death of the Old Devil Kings during the stalemate of the Great War. While the Old Satan Faction, Extra Demon Clans, and even the 72 Pillars were busy trying to accumulate power for themselves, this system was created in order to cease the Civil War and to remove heavy bias that lingered in the air after the conclusion of the War.

After Nicholas Satan took on the name of Great King, the system was completed and thus operations and funds were heavily spent on rebuilding the Underworld and aiding the bridged Nicholas had built with Heaven and with the Grigori; with Ajuka Astaroth creating both the evil pieces and brave saints to help repopulate both races and combining his power to create with Nicholas's immense demonic power to create a new Underworld for the Fallen Angels to claim as their own and thus creating boundary for Heaven, the Underworld, and Watcher (name given to second Underworld). The Grigori under Azazel however still use both their Underworld and Earth as bases of operations. The Three Super Devils of the New Satan Faction are Nicholas Satan, Saylena Beelzebub, and Ajuka Astaroth, however Ajuka is the only one who refused to become a King.

Nicholas Satan
Nicholas Satan rules as the Great King of the Underworld. He rules the domestic affairs alongside Caesar Lucifer however he mainly focuses on rulings of clans or families that don't involve the criminal courts, such as arranged marriages, possession over land, contracts, etc. An aloof, prideful, and childish king who mainly cares for his family and friends. He typically prefers to have these problems solved via fighting or Rating Games deciding that the strong should get what they want. However despite his personality because he has allied the three main factions under a ceasefire and stopped the Devil Civil War he has become known as a symbol of peace and will wear that title with pride and fulfill his work when he's in the mood to. His reason for being a Satan was because he thought it was cool.

Caesar Lucifer
Caesar Lucifer rules as the Second King of the Underworld who rules domestic affairs alongside Nicholas Satan however he focuses on the courts and upholding devil laws. Because of this he rules a army of knights that act as the Underworld police force known as the Kingsmen, who focus on bringing people to justice (criminals including stray devils) and having them face trials and sentencing. He is the only devil of the Great King who is originally from the Old Satan Faction, a serious, polite, and humble man who cares heavily for maintaining peace and uplifting the Underworld having been trained by Sun Wukong himself. He is considered the complete contrast to Nicholas as he takes his role very seriously and refuses to engages in behavior that would bring dishonor or shame to the Underworld. He takes a great deal of interest in the devil children of the Twilight Generation and hopes to see their rise to greatness. He became a Satan because he wanted to protect and uphold order in the Underworld.

Saylena Beelzebub
Saylena Beelzebub is the Chief Adviser of the Technology Department who rules with her husband Ajuka Astaroth in controlling the Rating Game system and Evil Pieces distribution, being the Satan who chooses promotees for high-class devil. A feisty, arrogant, and angry devil who Caesar Lucifer describes that due to her immense power she is the true heir for the name of Lucifer however she turned it down in order to work alongside her husband in his evil piece research. She cares and puts heavy emphasis on the power a devil possesses, stating that a devil without power or with natural talent is worthless, causing her ideals to clash with the other devils such as Caesar. However despite this belief she cares for the Underworld including her husband and son, who she believes is a problem child for both the Gremory and Astaroth Clan. She became a Satan because she wanted to protect the Underworld and help her husband with his evil piece system.

Arie Mammon
Arie Mammon is the oldest of all the Great Satans. He controls the economics affairs of the Underworld, dictating what the funds are used for, collection of taxes, and what areas to promote or expand. He was the devil who worked alongside Zekram Bael and Cyrus Paimon to create the new Seven Satan system, while he doesn't believe it to be perfect and realizes that it still holds some bias for the King Faction, he believes it to be better than the former system. While he cares about the other Great Satans he isn't ignorant to the problems Nicholas Satan and Saylena Beelzebub cause for him, due to their constant damages and lawsuits. He is noted to be the strongest physically of all the Great Satans and aided in the death of Ddraig by cutting off his wings, resulting in the loss of his arm which was destroyed by a combination of Ddraig's boosted dragon flames and several curses. He became a Satan to pay off his debt one day.

Valencia Leviathan
Valencia Leviathan is the devil put in charge of Foreign Affairs and as a result she works alongside her father, Ashton Orias, in maintaining contact with the Old Satan Faction, Extra Demon Clans, along with Heaven, the Grigori, and Demon World and as a result she is the head of the Underworld's Intelligence Agency known as Grimoire. While she is a battle maniac like her older brother, she is shown to be a more kind, patient, and humble individual who is the childhood friend of Ajuka Astaroth and Saylena Beelzebub, she takes her position as a Satan very seriously and even challenged Nicholas Satan for the position of Great Devil King on multiple occasions. She also possesses a very over protective personality that some view as over bearing calling her to be labeled a Helicopter parent by others and her daughter Dahlia Orias. She became a Satan to prove how strong she was.

Rhea Asmodeus
The most down-to-earth of all the Satans. She is in charge of the military forces and main fighting force of the Underworld and the second youngest of the Satans behind Nicholas Satan. A very calm young woman who looks for the solution with the least amount of effort. Despite being in charge of military affairs, she focuses mainly on solving situations in the most peaceful situation due to her distaste for confrontation and violence. Her main motivation for becoming a Satan was because she wanted to be more than just a Phenex devil and wanted to leave her own mark on the world. According to Caesar Lucifer, when she goes on vacation she leaves with her boyfriend and leaves her children at his door step.

Nero Belphegor
Nero Belphegor also known as the Mad Beast of the Underworld is a Satan who rules as Chancellor of the 72 Pillars, who acts as the manager in regards to handling dispute and controlling the clans. He is a very corrupt devil who merely became a Satan due to his loyalty to the Bael Clan and King Faction as a whole causing Arie Mammon and Caesar Lucifer to have some animosity towards him as the three oldest devils. His extreme loyalty to the King Faction is only rivaled by his pride and his immense demonic power which causes him to look down on high-class devils he considered inferior to himself. He is the younger brother of the Lord Bael and became a Satan due ironically to his loyalty to his family.
