Travelogue is a mod that adds a new item to the game, in this case it’s a book called “Travelog”. This book, as its translation from English (Travel Notebook) suggests, will record the biomes we have already explored and those that remain to be explored.
During our game in survival mode, we will surely explore certain biomes, and with this mod installed, the book will record the biomes explored. If we consult the book, it will indicate those that we have yet to explore. If we comply and visit the list of biomes, we will get a new achievement, the “Adventure Time”, with its subsequent reward.
