Dear friend,
you remember the treasure of the Conquistador, don't you? Well, you managed to impress an old friend of mine.
This friend lived for some time not far from an island where the first Europeans set foot. During one of his navigations in the sector, he anchored near a small old house.
He copied strange inscriptions (drawings, it seems). He would like to understand them, and for that, he is ready to give you things he has found on this island after spending weeks searching.
Knowing that you like these challenges and that you become the reference on the subject, I think I know your answer.
Good luck my friend. Ben Gunn.
