That's an exciting plot you got there and Joshua sounds awesome so I'd definitely be interested to be a part of this.
I have plenty of ideas of a character and one I can think off the top of my head is someone whose seen Joshua in her dreams, like a vision, since she's had a tumultuous upbringing as a shapeshifter (not a werewolf though, something as cool as Mystique from the X-Men movies who has a hatred towards humans) and somehow becomes obsessed with him and his philosophy so much so that she becomes involved as playing one of the good guys when in reality, she's carrying on his agenda while having the rest of the Order going in circles like fools.
If that's possible and you like my idea, please let me know,
@Nytefall!
