The Flying Blade is one of the artifacts of The Nine. The spirit of Relve Langral is bound to the sword and may be called forth by the sword's owner and will unquestionably follow the owner's commands. His mind was twisted by Myrkul and he enjoys killing. Relve's spirit is wreathed in blue flames when he is outside of the sword, which is why the Relve is referred to as a Blue Flame Ghost. The sword has been in the possession of the Stormserpent family of Suzail for many years.
