Back then, in the town of Woolpit, two mysterious children emerged seemingly from nowhere. They possessed green skin and spoke no English whatsoever.
Of the two children, the boy eventually died, but the girl managed to survive. As time went on, she also learned English.
In her words, the girl claimed she and her brother came from an underground area called St. Martin's Land. She says they came across a tunnel and decided to explore it, which eventually led them topside.
Many historians now claim the children's tale is one of time travel, and the "tunnel" that the boy and girl came through was actually a tear in the fabric of reality.
