Story description
''Midnight. A presence dominates your Lodgings. Its fur-trimmed robe is the red of blood on snow. Over your chair hangs a familiar brown sack, bulging with offerings. Londoners give generously to the Crimson Beast of Winter. Anything to be rid of it. The figure stares into the fireplace, smelling of soft musk and harsh ammonia. "I require a sturdy vessel and a captain. Yours comes recommended. You will suffice."''

At some point, you may be offered a Vial of Questionable Blood. If you use this instead of your own blood at the end of the quest, Mr. Sacks will fail.
