The Sacrifice

A village of normal humans who are being protected from evil wanderers (who eats people's soul), by a powerful unknown person. To appease the protector they must do whatever he says, but for several years he had not asked for anything not until today, their protector wanted a sacrifice , not just any sacrifice --a human. Their protector had sent people to look for a precise human "Fourth Nattawat" the son of an old lady that had passed away.
