I am not 100% responsible for the creation of Blazelight. The idea of this story came to me by a fanfiction called blood oath https://www.quotev.com/story/7031225/Blood-Oath-AU-PirateEngland-x-AssassinReader/1 by https://www.quotev.com/randommusicgeek. Blood oath is an amazing story by an amazing person, and both need love. 

But before reading that story, get into Hetalia beforehand, You don't want to read the story wondering what the hell is going on.
