Dortin, also known as Dortin Folcano, is a recurring supporting character in the Sorcerous Stabber Orphen series, including the Doom of Dragon's Sanctuary arc. He is a young dwarf from the southern region of Masmaturia, identified as a member of the Earth Tribe, and stands in contrast to his older brother, Volkan. Physically, Dortin is depicted as a teenage boy with short brown hair, blue eyes, and is frequently seen wearing a cape and distinctive swirl-patterned glasses, which contribute to his studious and somewhat nerdy appearance.

Personality-wise, Dortin is characterized by his intelligence, kindness, and cautious nature. He often serves as the voice of reason within his chaotic partnership with his brother, possessing a more pragmatic and thoughtful outlook that regularly goes unheeded. Unlike Volkan, Dortin is timid, gentle, and has a genuine passion for reading books, spending his free time learning and enjoying the scenery of their travels. This intellectual curiosity hints at a depth of character that his boisterous brother lacks. Despite his meek demeanor and the constant bullying he endures from Volkan, Dortin demonstrates a steadfast, if often reluctant, loyalty.

The primary motivation for Dortin is largely tied to survival and navigating the consequences of his brother's schemes. Exiled or having run away from home, the brothers travel together, frequently engaging in opportunistic and ill-conceived money-making plans that inevitably fail due to Volkan's impulsiveness. Dortin's own goal is often simply to avoid disaster, offering pragmatic advice that his brother ignores and frequently finding himself indebted to the protagonist, Orphen. This financial entanglement forces the brothers into an uneasy alliance, accompanying Orphen on various adventures as a way to repay their debts while continuing to hatch their own comedic plots.

Dortin's role in the story is primarily that of a comedic foil and a supporting ally. Alongside Volkan, he provides levity and a contrasting dynamic to the more serious main quest. The duo often interferes with Orphen's plans, inadvertently causing trouble, which typically results in them becoming victims of Orphen's retaliatory magical blasts, despite Dortin’s earnest protests of innocence. However, their role evolves from minor foes to contentious allies, with Dortin and his brother being employed by Claiomh Everlasting to perform odd jobs, further integrating them into the main cast's orbit. During key conflicts, Dortin shows flashes of unexpected courage and empathy, such as refusing to abandon endangered allies, revealing a hidden resilience beneath his cowardly facade.

The most significant relationship in Dortin's life is with his older brother, Volkan. Their dynamic is one of a comedic duo defined by squabbling and Volkan’s domineering leadership, which Dortin follows with a sense of resigned exasperation. Despite their dysfunctional partnership and the physical and verbal abuse Dortin receives, a bond of mutual reliance forged through hardship remains. In later arcs, Dortin shows signs of development, becoming slightly more assertive and occasionally defying his brother to do what he considers right, particularly when it comes to the safety of their companions.

In terms of notable abilities, Dortin does not wield magic but relies on his intellect and durability. His knowledge is his primary asset; he is well-read, potentially familiar with multiple languages, and often acts as the brains of the operation when it comes to assessing the viability of a scheme or understanding ancient texts. As a dwarf, he also possesses exceptional physical resilience, frequently and comically surviving Orphen's powerful magical attacks unscathed, a feat that highlights his species' sturdiness.
