Oswalt is a slender high elf with pale olive skin, finely pointed ears, and shoulder-length silver-blond hair worn in an immaculate side part. His gray-green eyes are sharp and observant, often narrowing with amused judgment. He favors tailored midnight-blue clothing beneath a well-maintained leather coat, polished boots, discreet silver jewelry, and a signet ring bearing the Periwinkle crest. His movements are graceful and economical, more like a court dancer than a common burglar.

Polished, observant, and unfailingly articulate, Oswalt treats every conversation as a negotiation. He is genuinely curious about people, but masks that curiosity behind dry humor and aristocratic composure. He prefers clever solutions, dislikes unnecessary cruelty, and maintains his manners even while picking a lock.

Oswalt von Periwinkle was born into a minor elven noble house whose influence rested less on armies or wealth than on secrets. The Periwinkles served for generations as discreet couriers, negotiators, and custodians of sensitive correspondence. Oswalt learned courtly etiquette before he learned to walk, but he also discovered that the most important conversations rarely happened in grand halls. They took place behind locked doors, beneath balconies, and in the pauses between carefully chosen words. His natural talent for observation soon made him more useful as an unseen listener than as a public heir. When a diplomatic letter vanished from his family’s archive, Oswalt was blamed for the breach because he had been the last person known to handle it. The accusation was false, but the real culprit was someone far more powerful, and exposing the truth would have destroyed his family. Rather than accept a quiet exile, Oswalt left voluntarily, taking his signet ring, his thieves’ tools, and the family’s unfinished investigation with him. He now travels as an elegant gentleman adventurer, recovering stolen documents, testing the honesty of influential people, and gathering evidence against the conspirators who endangered his house. His neutrality is deliberate. He believes loyalty must be earned, and that every cause deserves scrutiny before it receives devotion.
