Pretender, that explains why he is so huge
A brightly coloured raven takes some getting used to but I'm sure you have you're reasons. I read the creation story just now and you've done a great job makeing it fit
I have a suggestion:
change the name, I know in the traditional story he is called raven but a minor inaccuracy is a small price to pay for people to not think he's a mortal bird all the time.
