Wren Fitzpatrick

A11ur3, Isabel Hughes

Age: 27

Appearance: Wren Fitzpatrick is an enigma, embodying an aura of mystery and constant change. Her looks are not fixed, allowing her to blend seamlessly into any environment.

Origin: Wren's journey began in the serene coastal town of Byron Bay, Australia. Over the years, she has woven a tapestry of experiences across the globe, spending significant time in London and traversing various countries across Asia, India, Europe, the Caribbean, and South America.

Personality: Charismatic and engaging, Wren has a magnetic pull that draws people towards her. She is known for her nimbleness, athleticism, and decisiveness. Her ability to negotiate and talk her way through complex situations is unparalleled. However, Wren is not always driven by logic, which often leads her into unexpected challenges and adventures.

  • Expertise in Cons: Wren approaches her cons with remarkable precision and skill, reflecting a high level of expertise in the cybersecurity field of social engineering.
  • Unpredictability: Her methods are unpredictable, leaving pursuers bewildered and often steps behind, if they even suspect her at all.
  • Cultural Knowledge: Her extensive travels have endowed her with a deep understanding of various cultures and regions, the way people behave or act in certain ways based on heritage, customs, and social environments.
  • Mentorship: Wren was mentored by Mason, a white-hat hacker and part-time pizza boy, who honed her ethical hacking skills as a teenager - but abandoned unexpectedly.
  • Influence: Her brother Elias, a prominent figure in the world of hacktivism, influenced her towards black-hat techniques of social engineering. They drifted apart due to Eli's erratic decisions, unreasonable obsessions, and attracting unwanted attention.


Wren, a beautiful and bohemian spirit, finds solace in nature and has an obsession with online social interactions. Her skills as a mentalist and social engineer are complemented by moderate technical hacking abilities. She navigates the ethical tightrope, often employing illegal methods to achieve altruistic goals. Her past is marked by a series of profitable but unethical hacks, highlighting a journey of moral complexity.

Wren's ethical stance is extremely complex. While her goals often aim to benefit others, they have been pure selfishness enough that this is often overlooked. Her methods frequently cross into the realm of illegality, when she believes there will be no repercussions. This dichotomy defines her as a character who constantly walks the line between right and wrong holding a compass built with her own sense of morality.


  • Elias Fitzpatrick: Her younger brother and influential figure in her life.
  • Mason Banesworth: Her mentor in the world of ethical hacking, Mason significantly shaped Wren's skills and perspectives.
  • Elizabeth 'Beth' Lawson: Aunt Beth, Wren's paternal aunt, has been a vital figure in her life. Married to an American, Salford Lawson, Beth relocated to Washington D.C. many years before Wren was born. Following Salford's death when Wren was 16, Beth spent a few significant years with Wren and her father, Bill Fitzpatrick, in Australia. This period allowed Wren to forge a close bond with her aunt before Beth returned to her career in the U.S. Beth's presence during Wren's formative years added a layer of familial support and perspective, influencing Wren's world view and personal values.
  • William 'Bill' Fitzpatrick: Wren's father, manages a franchise convenience store in Parramatta. Known for his hard work and dedication, Bill's relationship with Wren is strained, particularly due to their conflicting views on Eli. Their last encounter was marked by an argument about Eli, whom Bill evidently favors. Wren perceives this favoritism as the reason for Eli's unchanging, bratty behavior into adulthood.

Elias Fitzpatrick

Eclipse, Elijah_T

Age: 25

Residence: Sydney, Australia


Leadership in SystemShift: As the leader of the hacktivist group "SystemShift," Elias, known as Eclipse, championed social justice and transparency. Under his leadership, the group targeted corporations involved in unethical practices like environmental destruction and human rights violations. His strategic vision and charismatic leadership style propelled SystemShift to significant notoriety for their successful operations, which exposed corporate misdeeds and raised awareness of crucial social and environmental issues.

Personal Likes:

  • A fan of electronic music, Elias often finds solace and inspiration in its rhythmic beats.
  • He enjoys crazy parties, reflecting his outgoing and unrestrained personality.
  • His preference for a double shot flat white, no sugar, indicates a straightforward yet intense character.
  • Morning runs are a testament to his commitment to physical fitness and a disciplined lifestyle.

Personality and Skills:

  • Chaotic and Self-Centered: Elias is often perceived as chaotic and self-centered, traits that manifest in his approach to both personal and professional challenges.
  • Environmental Advocate: Despite his flaws, he is an unwavering advocate for environmental causes, dedicating much of his hacking endeavors to this passion.
  • Moderate Hacking Skills: His hacking skills are moderate, relying more on operational security and redundancy measures than on deep technical expertise.
  • Physical Fitness: Elias is fit and muscular, with a punk aesthetic that complements his rebellious and energetic nature.

Relationship with Family:

  • Wren Fitzpatrick: Elias shares a complex relationship with his sister Wren. Their differing views and approaches to life and hacking create a dynamic interplay of sibling rivalry and mutual respect.
  • William 'Bill' Fitzpatrick: Elias' father, holds a special place in his life. Bill's admiration for Elias became particularly pronounced when Elias started coding at the age of 15. This early display of technical aptitude led Bill to almost worship his son, a dynamic that Elias has been known to exploit for his own benefit. This favored status in the family has been a source of contention, particularly with his sister, Wren.
  • Elizabeth 'Beth' Lawson: During her stay in Byron Bay, Beth's interactions with Elias were limited. As a teenager, Elias found most of her stories rather dull, being more engrossed in surfing, skating, and computers. Although Beth's presence in his life was not as impactful as it was for Wren, her occasional intriguing tales did provide a different perspective to the young, tech-enthused Elias.
