Samhain also known as Halloween is a spirit brought up in the dark ages of the boogieman or Pitch as the Gaurdians knew him. He is deemed a guardian when pitch returns somehow with more power than before. But what the Gaurdians don't know is Pitch and Samhain have a history that had kept him from being a Gaurdian centuries ago. I'm mainly doing this because I love Rise of the Gaurdians and it's almost Halloween
