In the John Wick franchise, a marker is a small round metal object indicating the debt of a blood oath between two individuals. Opening in the middle to reveal a divided surface, the debtor presses a bloody thumbprint on one side to commit an oath is owed, while the borrower likewise presses their bloody thumb to the other side to indicate when an oath has been fulfilled. Records of blood oaths are registered and tracked by the Continental luxury hotels.
