Though initially reluctant, he finds success farming for three years until market oversaturation causes prices to plummet. While playing a new video game called “Immortal Order: Origin” about historical secrets, he is mysteriously transported to 16th century North America, where he encounters starving English colonists from the lost Roanoke Colony. His grape farm has been transported with him, complete with modern equipment and a secret gift called 'Immortal'.
