You have stopped with the ship's crew on an island, long extinct and inhabited only by strange creatures, not at all like the species you are familiar with. Ruined houses, mold and darkness. That's all that greeted you upon arrival. Dead Island

Zoro, Luffy and Sanji went to wander the island and seek adventure, while you and Robin decided to dig through the ruins and find the cause of the island's death. She spent a long time wandering the remaining tropics and semblances of streets, touching ruined columns and digging through the rubble, but still no thoughts or guesses came to mind

"It must have been very different here before..." whispered Robin and looked at you. She was sad, and at the same time she was tormented by many questions, the answers to which were almost impossible to find "Imagine...there were children running down the street, picking marvelous fruits from the trees, and somewhere at home their parents were waiting for them, with delicious food. And in the center of town, beds of flowers, bushes. It could have been so cozy and so good here before, but in one moment, everything was destroyed...What do you think happened?"
