From Chapters 1-4 are just fillers and should not be considered too much. The story will technically Start on chapter 5.

Harry's sixth year to Hogwarts is full of adventure, a tale of a group that stopped and trapped a notorious monster that reaked havoc upon the land, a thousand years ago, is found by Harry and his friends.

This story goes along with the half blood prince, so there are a few spoilers in the story. Meaning that everything that I thought was important in the Half blood prince is in this story. And I am requiring that you readers give a suggestion for pairings.
