Klein Moretti begins as an ordinary Nighthawk investigator in Tingen, but his journey through the Tarot Club and the machinations of the Beyonder world steadily transforms him from a cautious, duty-bound gentleman into a calculating, multi-identity mastermind who balances secrecy with growing power. Across the volumes, his physical appearance remains that of a precise Victorian gentleman, yet his inner world expands dramatically as he juggles multiple personas—Sherlock Moriarty, Gehrman Sparrow, and the Fool—while navigating alliances, betrayals, and the ever-present threat of losing his humanity. By the later books, Klein’s evolution is marked by a deepening entanglement with ancient secrets, a widening web of relationships, and the constant tension between his protective instincts toward his family and his increasingly godlike ambitions.
Description
Klein Moretti has black hair and brown eyes, with common facial features, a clean face marked by deep contours, and a somewhat thin build. He dresses in formal Victorian style with a black double-breasted coat, top hat, and carries a black cane with silver inlays. His overall presence is that of a precise, understated gentleman suited to investigation and subtle intrigue.
