Caleb Barnes, at the tender age of 17, carries the weight of a world torn apart by the Outsiders. His curly dirty blonde hair often falls into his light brown, almost golden eyes, which carry a depth of sorrow and determination. Light brown freckles dot his face, a stark contrast to the hardened exterior he presents to the world. Standing at 5'9'', Caleb is clad in the typical Scout leathers: a brown leather tunic that clings to his lean, athletic frame, matching leather pants, and boots equipped with grippy black Scout gloves. These garments are not just armor but a symbol of his role and resilience in a fractured world.

As a Water Elemental, Caleb's abilities are tied to the life-giving and destructive forces of water, a reflection of his own tumultuous life. His personality is marked by friendliness, loyalty, and an unwavering protectiveness, especially towards his friends. His bond with Nova, a fellow survivor, is deep-rooted, though complicated by his unrequited love for her. Caleb's affection for Nova is intense, driving him to be fiercely determined in fulfilling her desires, even as she remains oblivious, her heart set on another, Gavin.

The tragedy that befell his family has shaped Caleb profoundly. His parents were turned by the Outsiders, and he was forced to confront the horror of putting his older sister into The Trench after her death. His younger brother, Oliver, only 9, remains his last living relative, a constant reminder of what he fights for. Caleb's life is a series of battles, both external against the Outsiders and internal, wrestling with his feelings for Nova and the grief of his losses.

Despite these hardships, Caleb's spirit remains unbroken. He navigates the world with a unique quirk: a habit of twirling a small, worn-out compass between his fingers, a memento from his father, symbolizing his quest to find direction in a chaotic world. His journey is one of survival, love, and the search for a semblance of peace in a world that seems intent on denying it.
