Originally I wanted to have two demon hunters (who appeared somewhat like witch hunters) to sent by the order of The Bleak Dawn to rid the town of the witch. These two characters would share a master and apprentice style of relationship with the young woman studying under under an experienced hunter.

 However over time I began to like this idea less and less and found my self drawn more toward a strong singular female warrior monk style of character. I wanted to keep the her affiliation with the bleak dawn and the reason she has been dispatched there but I realized I had not given much thought to who the Bleak Dawn were.

In my research I looked at giving her a Latin name but found it did not suit the character I had in mind however I originally planned to call her Angelus Lumine meaning Angel of Light in Latin (http://wiki.answers.com/Q/What_is_angel_of_light_in_latin)

Even though I did not like it as a name for the character this did however give me a bolt of inspiration as to her background and the role of the mysterious order of The Bleak Dawn.

Jhona Astora is a Nephilim a half angel dedicated to battling evil were ever it lurks and threatens the souls of humanity. This lead me into the idea that The Bleak Dawn is a secret order of Nephilim trying to regain their full angel status by aiding mankind and coming closer to the divine or godly realm the dimension of the gods and the centre of reality.
Of course there is always the possibility that a Nephilim could descend into darkness and become a dark angel or if given the right opportunity a Demon God or Dark God.
