Jake of the School of the Wolf, now known as the Founder of the School of the Raven, stands as a testament to both the old ways of the witchers and the birth of something new. His imposing figure, standing well over six feet tall, carries the distinctive marks of his profession - cat-like yellow eyes that seem to pierce through darkness and souls alike, and hair that turned silver-white during his unusually successful Trial of Grasses. A prominent scar runs across his left eye, earned during his first contract, serving as a constant reminder of the price of overconfidence.

His face, while maintaining the youth common to witchers, bears the weight of experiences across multiple realms. Deep laugh lines around his eyes contrast with the stern set of his jaw, speaking to both the joy he's found in his new purpose and the hardships he's endured. Jake's voice carries an unusual cadence, mixing the gruff northern accent of Kaer Morhen with occasional bird-like clicks and whistles - a peculiar habit developed after his encounter with the Matron of Ravens.

Trained personally by Geralt of Rivia, Jake moves with an almost supernatural grace, his movements precise and economical. He wears custom-made black leather armor, intricately decorated with silver raven feather motifs - a fusion of traditional witcher practicality and his new identity. Across his back, he carries two masterwork swords: a steel sword with a wolf's head pommel, a reminder of his origins, and a silver sword adorned with raven imagery, symbolizing his evolution.

Jake possesses an unusual trait for a witcher - a deep-seated need to preserve and pass on knowledge. This drive manifests in his meticulous documentation of monsters from both the world of the Witcher and Exandria, creating a comprehensive bestiary that serves as the foundation for his new school. His quarters are filled with journals, sketches, and detailed notes, reflecting an scholarly side that sets him apart from traditional witchers.

Despite his formidable abilities and accomplishments, Jake struggles with the weight of bridging two worlds. The traditional witcher's code of neutrality conflicts with his role as the Matron's champion and his growing attachment to Exandria. He maintains an unusual ritual of feeding ravens wherever he goes, a habit that other witchers find peculiar but which he considers a sacred duty.

In teaching his students, Jake has developed a unique hybrid style that combines the traditional witcher signs and swordsmanship with elements inspired by Exandrian magic and combat techniques. His school emphasizes adaptation and evolution, reflecting his own journey of transformation from a traditional witcher to something entirely new. Yet, beneath his confident exterior lies a constant questioning of whether he's betraying his original training or fulfilling a greater destiny.

The medallion he wears is unique - a silver raven with wolf's eyes, symbolizing the bridge between his past and present. It vibrates not only in the presence of monsters but also seems to react to the whispers of ravens, a constant reminder of his connection to the Matron. Jake's presence commands respect, but there's also an approachability to him that draws both students and common folk alike, breaking the traditional stereotype of the feared and isolated witcher.
