Who are The Faceless Men? History of Many-Faced God Assassins 

The Faceless Men and the Many-Faced God are some of the most intriguing aspects of the entire "A Song of Ice and Fire" series for me. An association of assassins, devotees of the god of death, possessing incredible abilities, and their whole history shrouded in mystery. Although the TV series already presented its take on this group, let's be honest-the potential was somewhat wasted. There's still a chance for Martin to bring this to a brilliant conclusion, with the story currently paused at Arya's training in Braavos.
