Sirgon wants to make use of his experience sailing around the Shield Isles to help you learn the geography with which you must now deal.
'Do not look so crestfallen, my friend! You must see that the Valar smile upon the Wave-hunter, and upon our voyage! We have our lives, after all, and the successful conclusion of your mission still lies ahead! This is not an ending, but a beginning! I have lost friends to the rocks that guard the Shield Isles, it is true... but today the strong hull of the Wave-hunter and the resilience of his crew has delivered us here safely. Rejoice for that, and celebrate the good fortune and the blessing of the Powers that aided in its accomplishment!
'I have not set foot upon this island chain in many years, but it will take me only moments to refamiliarize myself with them. If you will go to several locations and look, your report may help me remember the geography of these islands. Perhaps you can start at the beach across the lagoon to the south, a beach to the north-west of the Wave-hunter, and the beach on the western side of this island.'
Sirgon has asked you to look over your surroundings at three separate locations: the beach across the lagoon to the south of Sirgon, the beach to the north-west of the Wave-hunter, and the beach on the western side of the island.
