Doran's map of the Pirran Islands

Doran's map of the Pirran Islands was a map of the three Pirran Caverns beneath Deltora, the secret subterranean sea and the islands in them, drawn by the Deltoran explorer Doran the Dragonlover based on his expedition to the secret world below the world. The map was added to the Deltora Annals. In order to protect the Pirrans living there, no instructions in how to get to the caverns were provided.
