Rogue, born as Liam O'Donnell, is a man in his early thirties with a lean, muscular build, a testament to his life of stealth and agility. His hair is a dark brown, often kept short to avoid being grabbed in a scuffle, and his eyes are a piercing green, always scanning his surroundings with a cunning glint. His face is marked by a scar that runs from his left eyebrow down to his cheek, a memento from a close call during a heist. He dresses in nondescript, dark clothing that allows him to blend into the shadows, often adorned with a cloak that conceals his identity and the numerous pockets filled with tools of his trade.

Liam's father, an innkeeper, was secretly part of the Thieves Guild, a fact that led to his arrest and imprisonment when Liam was young. Left to care for his mother, Liam's childhood was marked by hardship and secrecy. As he grew, the same guild that took his father approached him, recognizing the potential in his lineage. Liam embraced the life of a thief, excelling in smuggling due to his cunning and deceptive nature. He uses ever-changing aliases to protect not only himself but also his mother, whose location remains a closely guarded secret.

A unique quirk of Liam's is a false tooth containing an herb that induces amnesia when bitten in a specific way. This is his last resort if captured, ensuring the safety of his mother's whereabouts and other critical information. Liam's primary goal is to provide for and protect his mother, a task complicated by the constant threat of exposure and the need to maintain his cover. He navigates this life with a blend of charm and deceit, always one step ahead of those who would seek to unravel his carefully constructed world.

The conflicts in Liam's life stem from his dual existence; the constant fear of discovery and the moral ambiguity of his actions. He justifies his thievery as necessary for survival and protection, yet the weight of his choices often haunts him. Despite these challenges, Liam's intelligence and adaptability have allowed him to thrive, though he knows this precarious balance could shatter at any moment.
