Albert James Moriarty, eldest son of Earl Moriarty, was born into late 19th-century British aristocracy. From childhood, he nurtured a deep disgust for the class system and nobility's mistreatment of commoners, frequently visiting a local orphanage to assist despite his status. His disillusionment grew upon realizing peers sought him only for social connections, breeding distrust of others' motives. A pivotal attempt to reform a thief ended in the man committing further crimes; this failure drove Albert to contemplate suicide, though he lacked the resolve to act. His path changed upon meeting William and Louis Moriarty at the orphanage. Inspired by William's speech advocating the elimination of corrupt aristocrats, Albert adopted both brothers. He proposed a partnership, offering his social status, fortune, and resources to advance William's ideals. This alliance culminated in the murder of Albert's biological family—strangling his mother and impaling his younger brother—and the arson of Moriarty Manor to stage their deaths. Albert, William, and Louis survived by hiding in the cellar, emerging as a new family unit under the collective identity of "James Moriarty," the Lord of Crime. Physically, Albert stands tall at 188 cm with a slender build, pale skin, brown hair styled with split bangs, and green eyes. He typically wears a dark green three-piece suit, green tie, and white pocket square. After three years of imprisonment, he loses weight, grows his hair longer—often tied in a ponytail—but retains his signature dark green attire. Albert exhibits a complex personality: charismatic and respected by peers, popular among noble circles despite renouncing his title. He extends kindness to commoners, maintaining a courteous and helpful demeanor. Yet, he harbors ruthless pragmatism towards corrupt nobles, viewing violence as justified for societal change. Academically gifted, he graduated as a King's Scholar and demonstrates strategic acumen. He notably seized an opportunity to establish MI6, a secret intelligence agency answering directly to the Queen, to funnel information to William's operations. Albert serves as the social face of their criminal empire, leveraging his charm to recruit allies. Key actions include orchestrating Baron Rollinson's poisoning to demonstrate the Lord of Crime's power to Irene Adler, manipulating government documents to blackmail Mycroft Holmes into protecting MI6, and supplying blackmail material to reformist MP Adam Whiteley. Albert also coordinated large-scale arson across London during "The Final Problem" to eliminate remaining corrupt nobles. Following William's presumed death, Albert surrendered to authorities, accepting responsibility for their crimes and entering self-confinement in the Tower of London. He suffered intense guilt, blaming himself for corrupting William and viewing their actions as "original sin." Upon William's survival, Albert reconciled with him, reaffirming their familial bond. Determined to atone, he committed to living alongside allies and supporting ongoing reforms. His personal likes include wine and family, while dislikes encompass prideful individuals and dust. He remains troubled by persistent marriage proposals from noblewomen despite his renounced status. Religious undertones, likely Catholic, influence his worldview, evidenced by frequent biblical references.
