An organization made up of remnants of the long defunct Atlantean Empire, whose goals are quite obscure. They were seemingly active during the 19th century under the leadership of a resurrected Herpo the Foul, but faded back into obscurity after his defeat. The organization was seemingly revived in the 20th century under a man known simply as the Professor, and they serve as the main antagonist force of the story.
The Eternal QueenThe main antagonist of the story, she is the true leader of the Consortium, expressing her orders to her faithful commander, the Professor. In life, she was the wife of Anipheon IX, the Divine Sovereign of the Atlantean Empire, but both were defeated by Cloteias.
- Ancient Evil: She predates all modern humans by thousands, if not millions of years, and in her prime she ruled over a region of the Atlantean Empire. The Aenean religion sees her as an incarnation of the Adversary, something which was also confirmed later by the Mandarin.
- Big Bad: Despite being mostly dead, whatever remains of her commands the Consortium, which seeks to resurrect her.
- God Save Us from the Queen!: It is stated that she committed many atrocities during her life, and will probably commit more if she is allowed to be resurrected.
- Greater-Scope Villain: Served as this during Voldemorts first campaign in Britain. No one except for him knew she even existed.
- I Have Many Names: Has been referred to as the Eternal Queen of the Seven Cities, the Black Mistress, the Sleeping Messiah, the Harvester of Souls and the Demoness of Temptation.
- Satan: As mentioned above, it has been stated that she is the most recent incarnation of the Adversary.
- Sealed Evil in a Can: After being killed during the Third War of Righteousness and her Nucleus somehow remaining on the mortal world, she was reduced to this, "imprisoned" within her own Nucleus. Her influence is merely restricted to mental whispers and promises of power, not capable of doing anything more complex than that.
The Professor/ Ruslan MikhailovskyWith the Eternal Queen unable to lead the cult, the Professor serves as the de facto leader of the Consortium, all operations being commanded and orchestrated by him. When not in his role as the Consortium's leader, he is the head of the Imperial Institute for Deficiency and Mental Diseases and also the founder and leader of the Carbonek Institute.
- Benevolent Boss: He is somewhat portrayed as one.
- The Dragon: To the Eternal Queen.
- Dragon-in-Chief: Due to the state of the Eternal Queen, he commands the Consortium.
- Evil Genius: He has somehow succeeded in altering the structure of the Nucleus, and how to implant them in living people, creating strange creatures who have absolute loyalty towards the Eternal Queen.
- Everyone Calls Him "Barkeep": He is simply known as the Professor.
- The Mole: Revealed to be one for Harry's side.
- Monster Progenitor: Although not one himself, he created a bunch of humanoid abominations by infecting the Nucleus of non-magical humans with a corrupted Nucleus.
- The Professor: A not so good-aligned version of this. He was once a professor in magical Moscow, and the title seems to have remained with him.
Lord VoldemortOriginally known as Tom Riddle, Voldemort pledged himself to the Eternal Queen at an uncertain point in his life, becoming one of her top lieutenants.
- Demoted to Dragon: An out-of-universe example. Voldemort is not the main antagonist force in the story, and was introduced as having been subservient to the Eternal Queen in the backstory.
Divine SovereignsThe autocratic, theocratic and magocratic rulers of the old Al-Antidian Empire, best known in popular culture as Atlantis. The first was Amilanius, and all that followed would descend from him.
- Ascend to a Higher Plane of Existence: After being killed during his battle against Cloteias, he became a full Perennial.
- Bastard Bastard: The illegitimate child of Oiraps VIII, but curiously his successor to the Alluvial Throne despite the existence of legitimate half-siblings, something which infuriates his stepmother. Despite all, Anipheon blackmailed her with exposure of heresy and had plans for her permanent disappearance. And then there were also the events that led to the rebellion against him.
- Childhood Friend: Before the rebellion against him, he and Cloteias had been best friends since their childhood.
- Half-Human Hybrid: In life, he was a Human-Perennial hybrid. After his death, the Human half is consumed by his Perennial half.
- God-Emperor: He was the Divine Sovereign of Al-Antidia.
- Gray Eyes: He has these.
- Greater-Scope Villain: For the events that occurred since the Eternal Queen resurfaced. It has been stated that she is still loyal to him. The revelation of Harry as his reincarnation makes that a bit confusing.
- Older Than They Look: When he was nearly twenty years old, he still had the body of a young teenager.
- Reincarnation: After becoming a Perennial, he somehow was reincarnated as Harry Potter.
- Youngest Child Wins: Inverted. He was the firstborn of his father and also a legitimized bastard. Even though his father married a woman and had children with her, he still succeeded him as the Divine Sovereign.
The ExaltedAmongst the castes of Al-Antidia, the Exalted caste is the highest one, standing directly below the Divine Sovereign and above all others. However, only twelve members can exist at a time, each being the high priest of one of the Sacred Twelve.
Diviner of the Ideal WorksThe title given to the High Priest of Ayavan. The holder of this position is also the leader of the Paramount.
- Body Horror: Despite the already long lifespan of Atlantean humans, Nederel extended his own life with many experiments, leading to a permanent disfigurement of his face and the mutation of his very skeleton. His skeletal appearance also does not help matters.
- High Priest: He was the High Priest of Ayavan during the reign of Divine Sovereigns Protion VII, Oiraps VIII and Anipheon IX as well.
- Immortality Seeker: Subverted. While he sought to extend his own lifespan, Nederel did not seek to become immortal, only wanting more time to complete his research.
- Magic Enhancement: His experiments certainly enhanced him, but altering much of his appearance.
- Reasonable Authority Figure: One which Anipheon himself respects, despite the fact that Nederel is technically below Anipheon in the hierarchy.
Appraiser of the Wayward WhimsThe title given to the High Priest of Teutates.
- Blue Blood: He was born as a member of the fourth dynasty of Al-Antidia, being the grandson of Divine Sovereign Taioron II.
- Egopolis: He shares his name with the city-state of Iridal, which he founded and ruled over until his death.
- Founder of the Kingdom: As stated above, he founded the city-state of Iridal and became its king. The Kingdom of Iridal was ruled for many generations by his descendants - the House of Iridal and the House of Iridal-Nedeus.
- High Priest: He was the High Priest of Teutates.
- Posthumous Character: He is the main ancestor of the Eight Dynasty and by the time of Anipheon he has been dead for several millennia, having been himself a member of the Fourth Dynasty.
Harry-Anipheon (Dark Nucleus arc)After touching the corrupted Nucleus in the Magnaura, Harrys own became infected with the corruption created by the Consortium. Harry-Anipheon is the result of said corruption fully taking hold of his Nucleus.
- Arc Villain: He is this for the Dark Nucleus arc.
- A God I Am: Clearly thinks of himself as one, mostly due to his origins as Anipheon.
- Chekhov's Gunman: He was originally introduced in chapter 11 as an unidentified shape taken by Harrys boggart. Only in chapter 36 would he be properly introduced and revealed as Harrys own corrupted form.
- Superpowered Evil Side: For both Harry and Anipheon IX. He was capable of deflecting several spells from the staff of Hogwarts without doing much, and later gather them in a single blast of magical energy directed at them.
- It Can Think: The only Corrupted capable of coherent thought. It helps that he was created from the Nucleus of a Human-Perennial hybrid.
- Kill It with Ice: As with all Corrupted, ice is Harry-Anipheon's greatest weakness. He is destroyed by a combined attack of Glacius charms from the professors of Hogwarts and a group of students, the power of said spells amplified by a strange entity.
- Rage Against the Heavens: He believes that after originally dying, Aion abandoned him. As such, he now seeks vengeance against him.
