Dark Brotherhood (Skyrim)

The Dark Brotherhood is a group of assassins who are willing to assassinate virtually anyone as long as they are paid enough for the service. They are a perverted offshoot of the "legal" assassins guild, the Morag Tong, who are based in the province of Morrowind; while the Morag Tong were a respected, if feared member of Morrowind society, the Dark Brotherhood are a secretive underground cult that worshipsSithis, the avatar of death.
