The Cartographer is a Continental Service that provides maps and blueprints for assassins to use best hunt their target.
Behind a false bookcase in a small bookstore is The Continental's Cartographer. The Cartographer's map collection is full of both ancient diagrams and modern blueprints, detailing the layout of many local sites. The Cartographer reviews his clientele's travel plans and helps to provide all the logistical data necessary for their missions.
In addition to these manuscripts and documents, the Cartographer can also provide the keys necessary to access certain areas, aiding John Wick in gaining covert access to the Red Square concert venue in the Roman Colosseum.
