The Green Children of Woolpit

In the mid-1100's wolves and creatures roamed the forest of Woolpit, England. To keep out the dangerous beast from harming the forest villages, locals dug huge pits and holes in hopes of capturing the creatures before they could do any damage.
But one afternoon the local field workers found a shocking discovery. Curled up in one of the wolf hole sat a small brother and sister....with bright green skin. With an unfamiliar language, and clothes unlike any other, the villagers dug in deeper to figure out who and what were the Green Children of Woolpit.
