DeMarco Meets With Scarlett
On Day 3, DeMarco sent messages discreetly to people who could help him prepare his departure from the Sea of Thieves in secret. His ship — The Midnight Prowler — was too well known, and he had to sail with a new Galleon to go unnoticed.
On Day 4, in the evening, DeMarco went to Marauder's Arch with a rowboat and then shared a seat with Scarlett — the shipwright on Galleon's Grave Outpost — high up on the Skeleton Throne at the peak of the island.
DeMarco was pointing out towards the West whilst Scarlett looked at him, holding a Compass that pointed North.
