Agent Regulus carries the agent badge and the Cane Corso build, which together makes other pups answer questions slowly and politely. At sunset Agent Regulus sits by the bone polishers den and hums to a coin with a face nobody recognizes until the wind returns the favor. Agent Regulus arrives where soup is served and somehow always after the line has shortened. When archive rumors move through The Yard, Agent Regulus is usually nearby before the rumor knows where it is going. Legendary detail: When the wall under the flying den whispers class subject recognized, Agent Regulus is the kind of pup the phrase seems to mean, which is why even Gator Jaw will hold a route open and let an Agent pass without comment.
