Sirius

Biodata

Background / History

Sirius belongs to the Black family, one of the Sacred Twenty-Eight pure-blood families. A notorious rebel within the household, he ran away at sixteen and severed ties with his relatives. After graduating, he joined the Order of the Phoenix and became one of Dumbledore’s most trusted fighters 62.

He was originally the Potters’ Secret Keeper, but arranged for Peter Pettigrew to replace him. Sirius expected Voldemort to pursue him and believed the substitution would keep James and Lily safe even if he were captured. Peter instead betrayed their hiding place 76.

After the Potters’ deaths, Sirius pursued Peter from Godric’s Hollow to London. Peter caused an explosion in Westminster, killed thirteen Muggles, and escaped in rat form after leaving behind a finger to fake his death. Sirius was arrested less than two days after Voldemort’s fall and blamed for both the betrayal and the explosion 62 75 76.

The Black ancestral home had passed into Sirius’s ownership three years before his acquittal. His work fighting Voldemort had kept him away, leaving the house neglected and largely in Kreacher’s care 76.

Appearance

• Build: Tall and approximately Lin Ze’s height, with long legs 66 211 258.
• Hair: Long, black, and slightly curly; often tangled or unkempt 62 258.
• Face: Pale, with a fierce expression that appears friendlier when he smiles 258.
• During his hearing: Disheveled, unfocused, and withdrawn, with tangled hair hanging over his shoulders 62.
• After his release: Wears a dark coat with its collar turned up; his hair becomes noticeably tidier 115.
• After Constantine’s imprisonment: Severely thin, with prominent cheekbones, sunken eyes, longer hair, and torn, faded robes 262 263.

Personality

Sirius is rebellious, outspoken, and resistant to coercion. His break with the Black family begins in adolescence, and imprisonment does not make him submit to Constantine: he explains that being locked away only made him less willing to cooperate 62 263.

His loyalty to his friends can become self-destructive. Believing his decision to change Secret Keepers caused the Potters’ deaths, he initially pleads guilty and refuses to defend himself. Lin Ze’s suggestion that Peter survived gives him a reason to fight the charges, transforming his courtroom demeanor from apathy into open defiance 63 64.

Sirius is blunt about revenge, openly telling Lin Ze that he wants Peter dead even if pursuing him risks another arrest. His concern for Remus Lupin shows a gentler side: he fears that prejudice against werewolves has left his friend isolated or in danger 67 73 115.

He retains an irreverent sense of humor through hardship, teasing Lin Ze and enthusiastically encouraging him to assume the identity of Merlin. He also enjoys drinking; Constantine exploits this habit to capture him while he is intoxicated 263 265.

Story Role / Major Arcs

Trial and Acquittal

• Initial hearing: Pleads guilty but refuses to explain the alleged crimes. His prolonged laughter disrupts proceedings until an Auror silences him and Crouch adjourns the hearing 62 63.
• Change of testimony: After Lin Ze challenges his self-blame and questions whether Peter truly died, Sirius identifies Peter as the actual Secret Keeper. He demands that the prosecution produce evidence rather than requiring him to prove his innocence 63 64.
• Bargain with Lin Ze: Refuses to leave detention without speaking to Lin Ze, then offers his services in exchange for finding Peter and learning his eventual transport route 66 67.
• Retrial: Requests Veritaserum for both himself and Peter. Their testimony establishes Peter’s voluntary betrayal and Sirius’s innocence; all charges against Sirius are dismissed 75 76.
• Peter’s transport: Lin Ze supplies the transfer time and route. A later witness reports that a large black dog deliberately targeted and bit Peter to death during the convoy attack; the account does not explicitly identify the dog as Sirius 77 94.

Remus and the Black Family Archives

• Asks Lin Ze to help locate Remus, fearing that rejection of werewolves has forced him into hiding or exposed him to something worse 115.
• Assists Lin Ze’s investigation into Chivalis Black, identifying him on the family tree as his great-great-great-grandfather’s younger brother 172.
• Opens the family library to Lin Ze, whose Revealing Charm uncovers a cobweb-covered door Sirius never knew existed 172.

Tintagel Expedition

• Accompanies Lin Ze and Mia to Tintagel, recalling that older Black relatives considered it unsafe and that he previously visited with James 211.
• Enters the opened archway first and explores the structure beneath it with the others 214.
• After escape attempts fail, follows the group through a rift to the Other Side 216.
• Meets Yilai, the ancient gatekeeper who describes Merlin’s door connected to death and asks the travelers to kill it with a key marked “The way home” 217.

The Witch King and Arthur’s Claim

• Establishes himself in Arthur’s era as the Witch King and circulates notices searching for Lin Ze 263.
• Is imprisoned for nearly two years after refusing Constantine’s demand that he destroy an army of three thousand. Constantine captures him by getting him drunk and fitting him with Magic-Suppressing Stone shackles 263.
• Is rescued by Lin Ze. Sirius’s exclamation invoking Merlin is overheard by a guard, causing the palace to identify the rescuer as Merlin 262 263 265.
• Encourages Lin Ze to adopt that identity and proposes manufacturing a Sword in the Stone spectacle to support Arthur’s accession 265 267.
• Accompanies Lin Ze into the northern bone cavern and later fights Constantine’s forces and Shedding Gods in the palace 270 271 277 279 280.
• Travels to the Tree of Life with Lin Ze, then joins the return journey to Morgana with Mordred and the recovered finger bones 282 283 286.

Return to London and Ministry Investigations

• Enters the river of time with Lin Ze under Morgana’s instructions. Both resist answering a voice resembling Mia’s and escape back to London 288.
• Receives an Auror badge and investigates communications connected to Hugh Greengrass’s escape 294.
• Watches the White Raven Chamber of Commerce over several nights. After discovering a large gathering, he is ambushed, wounded, and forced to leave the captured Ben and Weiqi to seek Lin Ze’s help 298.
• Helps search properties linked to Claude Weil and returns a prisoner to the Ministry while Lin Ze investigates Holloway 300.
• Finds ancestral alchemical records linking suspicious devices to Ouroboros and a warehouse on the Cornwall coast 305 306.
