The Monster Within.

My name is Arthur Dumas, code name 'Calamity', I served as a child mercenary for the group known as 'Humanity's Sin'. I have been deployed on the borders between the Kingdom of Smedia and the Himera Empire.  My life thus far can be summarised as a series of wars in which I excelled, having 600 confirmed kills to my name with thousands rumoured to have been caused by me. However an unknown 'illness' has forced me to retire from the  group and try to build a life for myself. The 'illness' is not real, my constant killing has activated the dormant bloodline within me, the bloodline forces me to devour in order to feed it and in return it makes me stronger.  Every time I devour someone it makes me need to feed more, the beast demands tribute, I the mercenary  king demand your tribute!
