Port Report

 is a Curiosity item you can acquire by travelling to the various ports in the Unterzee and gathering rumors.

When you deliver your first  of any port -- except the Cumaean Canal Staging Area -- to The Admiralty Survey Office in London, you will get +1 x Admiralty's Favour in addition to 1 x Fuel and a set amount of Echoes. Delivering the same report again will only get you Fuel and Echoes, unless you are able to successfully present A Port Report: Shepherd Isles as fact.

The Iron Republic is a special case. The Republic is a project sponsored by Hell; the Port Report: Fallen London which can be obtained there - when Another Day: Iron Republic Days = 15 - must be sent to The Brass Embassy, Hell's diplomatic mission in London.

Once you have surveyed an eligible port, you will get an Accomplishment in your Journal.
