History

Legends of time travel have captivated scientists and laypeople alike. One remarkable story tells of a man who arrived in Tokyo carrying a passport from a country called Taured—a nation no one had ever heard of. He pointed to Andorra on the map, but the country did not exist. Customs officials found documents and checks from Taured in his possession before he mysteriously vanished without explanation.

In 1936, residents of a small California town reported seeing an elderly woman in unusual clothing who, when offered assistance, ignored them and then simply evaporated before onlookers’ eyes. Countless similar tales persist, and whether you believe them or not, today is the perfect day to embrace the mystery!
