The Antique Navigation Globe is an artifact left behind by the old Lighthouse Keeper of Markham's Isle. In the T2 mission "Precious Cargo", Garrett has been commissioned to steal it for a "smuggler friend".[1] A secret switch in the attic allows access to the crawlspace on the second floor of the dilapidated house where it is hidden.
The globe itself depicts a large continent resembling Antarctica surrounded by large islands.
