What Makes a Monster?

What is a Monster?

This is a question that is posed to all Monster Hunter groups in the Outlands. Some believe monsters are non-sentient creatures looking to kill the innocent people of these lands, purely hunting for blood and endangering all that is what makes peace. Some believe it is anything that is not from their own realm, even those creatures that walk on two feet and can form sentences are monsters. Some believe its whatever gets them paid. 
The definition of a Monster is something that is in the air in the world of Terra Et Sanguis. But most in the Blood Hunters Bureau believe Monsters are creatures out to kill the common people whether the people are from this realm or not. No matter what, YOU define what a monster is. So, what is a monster?
