The Jackal is a shadowy figure in the world of underground crime, an almost mythical presence known for his ruthless cunning and surgical precision. No one knows his real name or what he looks like, as he's always seen wearing a high-tech mask that mimics the face of a jackal. His backstory is wrapped in rumors: some say he was a black ops soldier who got betrayed by his own government, while others whisper that he's a rogue AI given flesh and bone. The truth, as with everything concerning the Jackal, is shrouded in mystery.

Physically, the Jackal is unassuming, average in height and build. He favors functionality over flash, wearing a set of matte black combat armor laced with muted technomagic runes. These runes enable him to blend seamlessly into shadows and dampen sound around him. His primary weapon is an intelligent monomolecular blade called "Night's Whisper," which can cut through most materials with ease and possesses an autonomous tracking system.

Traits:

1. Shadowmeld: Utilizes technomagic to become nearly invisible and silent, allowing for extraordinary stealth capabilities.

2. Data Phreak: Exceptional at hacking into secured systems, including both technology and arcane barriers, giving him unprecedented access to information.

3. Blade Master: Immensely skilled in close-quarters combat, his blade "Night's Whisper" adapts to his combat style and the vulnerabilities of his enemies.

4. Tactical Genius: Extremely analytical and can quickly assess situations to formulate the most efficient plan of action.

5. Mystic Tracker: Employs a combination of ancient rituals and state-of-the-art tech to find anyone or anything across dimensions.

6. Emotion Dampener: Through some form of technomagic or advanced psychology, he can suppress his own emotions, making him impervious to mind-altering effects and enhancing his decision-making under stress.

Feared by the law and even by other criminals, the Jackal is a technomage assassin who excels at the art of disappearance. Once he takes on a contract, the target's fate is almost universally sealed. But for all his infamy, the most perplexing thing about the Jackal is his own set of morals, a personal code that he adheres to religiously, though its tenets are known only to him.
