Background / History

Origins and Adoption

Argus transmigrated into the magical world as a baby abandoned outside a British orphanage. Familiar with Harry Potter’s world from his previous life, he initially believed he had merely been reborn. His magical awakening at five—and the Acolytes subsequently bringing him before Gellert Grindelwald—revealed where he actually was 1 3.

An orphan of the Grindelwald family, Argus became Gellert’s adopted son. Their relationship developed into a close father–son bond despite their not spending every day together. His heritage also made him a target of scrutiny from the Ministry of Magic, the Acolytes, and the Wizards’ Council, prompting him to conceal his progress while building his abilities 1 4 14.

Taking Command of the Acolytes

On his eleventh birthday, Argus insisted on inheriting leadership of the divided Acolytes despite Vinda Rosier and Abernathy’s warnings. Addressing the gathering, he used a skull-shaped pipe to project images of Muggle weapons, spacecraft, and satellites, arguing that technological development vindicated Grindelwald’s warnings 1 2.

An Auror attack interrupted the gathering. Argus stopped Vinda from killing the captured Aurors, evaded another Killing Curse from their leader, and cast Protego Diabolica. The Acolytes passed through his flames before Apparating away, and the system recognized his assumption of command with 500 achievement points 3.

Argus chose Britain as the organization’s new base and Hogwarts as his school. He ordered the Acolytes to liquidate their holdings, abandon anything they could not sell, and relocate that night. Their withdrawal preceded a joint operation by the German and Austrian Ministries 3 4 5.

Establishing Himself at Hogwarts

Before term began, Argus befriended Draco Malfoy and Harry Potter, persuaded Draco to apologize for insulting Hagrid, and began cultivating connections with Britain’s younger pure-blood generation. By late August, he had completed the Hogwarts textbooks through fourth year and was reading the fifth-year Standard Book of Spells 7 8.

On the journey to school, he cleared Draco of stealing Neville’s toad and encouraged Harry, Hermione, and Neville to consider houses beyond their initial preferences. His advice helped influence Hermione’s choice of Ravenclaw, although Harry ultimately remained in Gryffindor 10 11 13 14.

Sorted into Slytherin, Argus quickly secured the first-year chief position and challenged older chiefs. He subsequently occupied the house’s number-two seat and organized older students to help first-years find their classrooms. His Transfiguration work earned McGonagall’s attention and an invitation to her club 14 16 17 19 20 21.

Conflict with Ron Weasley

Ron’s accusations against Draco developed into repeated confrontations with Argus. During Flying Class, Ron charged at him on a broom and later collided with Draco. Argus transfigured the grass into mattresses to cushion Draco, then discreetly cast Finite Incantatem on Ron’s broom, causing a fall that severely injured Ron’s arm 10 25 26 27.

Argus later accompanied Draco to a midnight duel against Ron, with Harry serving as Ron’s supporter. After the confrontation, Argus used his friendly relationship with Filch to leave Harry and Ron facing punishment while he and Draco returned to their dormitory 39 40.

Voldemort’s Disciple

An encounter with Quirrell during a nighttime excursion brought Argus to Voldemort’s attention. Voldemort eventually revealed his identity and demanded that Argus submit to him. Argus refused, and their ensuing duel ended with Voldemort easily overcoming him as his magic weakened 30 36 37.

Recognizing Argus’s talent, Voldemort instead offered to teach him. Argus accepted the arrangement as an exchange of information for genuine magical knowledge, not an unconditional pledge of loyalty. He supplied information about Harry and Fluffy while withholding crucial future knowledge, including Harry’s connection to Voldemort’s soul 37 38 43.

Building the Diagon Alley Business Group

Argus arranged to purchase Hagrid’s Forbidden Forest materials at market price, securing a supplier whom other buyers had routinely underpaid. He also invested in Fred and George’s inventions, offering fifty Galleons initially, material costs, and a future joke shop in exchange for half the profits and one of every product 28 32.

For the Acolytes’ Diagon Alley shops, Argus proposed giving the Ministry ten percent of profits in return for protection against hostile pure-blood interests. He separately obtained Dumbledore’s promise to help handle interference from pure-blood families in exchange for occasionally guiding Harry 41 45.

His plans encompassed twenty or thirty shops, including businesses challenging established monopolies. At the opening, he appeared alongside Fudge and launched discounts backed by extensive stocks of magical materials. After seeing the warehouse and learning about the Hagrid partnership, Lucius Malfoy pledged his family’s loyalty as a business partner. The system later awarded Argus 100 points for establishing the business group 48 49 50.

Appearance

  • Blond hair and blue eyes, repeatedly compared with Gellert Grindelwald’s features 6 12.
  • Aristocratic bearing, reinforced by cultivated manners, formal bows, and a controlled, polite smile 6 7 14.
  • Left Eye of Prophecy, inherited through the Grindelwald bloodline 34.

Personality

Argus presents himself as gentle, composed, and courteous. He reassures insecure classmates, teaches students regardless of house, and treats people such as Hagrid and Filch with respect. These habits win him support from students and favorable impressions from professors 12 21 32 33 40.

His private calculations are considerably more strategic. He initially views Draco as an entry point into pure-blood society, attempts to influence Harry partly to complicate Dumbledore’s plans, and exploits both Dumbledore’s principles and Voldemort’s ambitions. Friendship, public reputation, and commercial relationships all serve his broader goals 5 7 11 37 41.

Argus’s restraint is conditional rather than absolute. He prevents Shafiq from being injured in their duel and speaks of magic as protection, but retaliates covertly against Ron and seriously wounds Ronan when threatened. He is willing to use force decisively while maintaining a gracious public image 16 26 34 41.

He also recognizes the gap between talent and actual strength. His encounter with Voldemort exposes his limited magical reserves and combat experience, driving him to seek instruction and a private practice space. After Vinda demonstrated the importance of physical movement, he adopted a regular exercise routine 31 38 39.
