Basil, a changeling of indeterminate age, serves as a private detective in his home kingdom, often collaborating with soldiers and guards to unravel complex cases. His unique nature as a changeling allows him to assume various forms, but he most frequently appears in two distinct guises. In private, Basil adopts a common changeling form characterized by pale skin, long white hair that cascades to his shoulders, and milky white eyes devoid of pupils. This form is a reflection of his true self, a sanctuary from the world's prying eyes. When on cases, however, he transforms into a more imposing figure with raven-black hair pulled into a long, pointy tail, pale tan skin, and piercing blue eyes. His attire in this guise is a fancy blue and black suit complemented by a black cravat, black boots, and fingerless gloves, which together project an air of authority and mystery that aids him in his investigations.

As a rogue shadow-touched sorcerer, Basil's intelligence and inquisitiveness are matched only by his proficiency in languages and his knowledge of chemistry and alchemy. These skills are invaluable in his detective work, allowing him to decipher clues that others might overlook. Basil's latest case involves tracking down an escaped criminal, a challenge that excites his curious nature and pushes his abilities to their limits. Despite his brilliance, Basil's enthusiasm for certain subjects can lead him to overlook the broader picture, a quirk that sometimes complicates his investigations.

Basil's life is a tapestry of intrigue and conflict. His work often puts him at odds with powerful figures who would prefer their secrets remain buried. Moreover, his dual nature as a changeling and sorcerer creates an internal struggle, as he navigates the expectations of his kind and the demands of his profession. Yet, it is through these challenges that Basil finds purpose and satisfaction, using his unique abilities to bring justice to a world that often shuns those who are different.
