The Rake is the Fear of brutality and animosity. It's stature and behavior is beast-like, however, this has been recently found to be a mere act. The Rake is far more intelligent than it lets on and also is not the singular being it is thought of as.
Admittedly there is one true Rake which we know is the center of the operations, but surrounding it are packs of other beings identical except for one factor, the original Rake has part of its claw missing after a fight with the Late Fear hunter Francis Francois, others do not, however they could easily get in similar fights to mimic such a battle scar.
The Original Rake can recruit servants via his constant whispering which drive people to madness, these servants are known as Maenads.
