Kaplan is a broad-shouldered human with a weathered face, close-cropped dark hair, and a narrow scar running from his left temple to the corner of his mouth. His clothing was once the formal black-and-copper uniform of a respected mercantile security company, but it has been repaired and modified into practical rogue's gear. He wears a dark leather coat, soft boots, a red silk tie used as a bandanna, and a brass company badge with its crest deliberately scratched away. His hands are callused from years of climbing, lockwork, and sword practice.

Kaplan is observant, pragmatic, and unexpectedly protective. He speaks like a former professional, carefully cataloging risks, obligations, and exit routes, but he has a soft spot for debtors, dismissed servants, street children, and anyone being crushed by a system too powerful to fight alone. He prefers clever solutions to violent ones, though his broad frame and intimidating stare make it clear that cleverness is not his only option.

Kaplan once served as an agent for the Meridian Indemnity Company, a private firm that handled investigations, asset recovery, and discreet protection for merchants and nobles. He was not merely a thief in uniform. He tracked stolen property, uncovered fraud, and escorted witnesses through dangerous districts, using his strength when intimidation was needed and his hands when subtlety was more appropriate. The company gave him a place in the world, a badge that opened doors, and a salary that let him believe he had escaped the streets where he was raised. Then the Meridian Indemnity Company collapsed. Its directors fled after a scandal involving forged contracts, seized estates, and a campaign of illegal intimidation. The courts declared the company bankrupt and sanctioned its operations, leaving its agents disgraced and its clients abandoned. Kaplan escaped with little more than a damaged badge, a list of unpaid obligations, and proof that the directors had engineered the downfall to erase evidence of their crimes. Now he works as a freelance criminal, investigator, and occasional burglar, using the skills that once served a corrupt institution to repair the harm it caused. He intends to restore his name, expose the people responsible, and build something better from the ruins, even if the law still calls him a criminal.
