Traveler's Journal is a tome in Act I of Diablo III. It is needed to complete the achievement Historian of Tristram and it can be found on Old Tristram Road on an Adventurer's Corpse. It reads as follows: "While exploring a cave with hopes of finding hidden treasure, I came upon a most grisly sight - a heap of dead bodies. Unbelieveably, as I was searching them for any items of value, they began to rise! I must tell them of this in New Tristram before it's too late." ~Theren the Traveler
