I've been reading some legends when crows and ravens were pure white and used to sing rather than croak.

He is my imagination when all crow used to be blank white and innocent. Though he's some sort of guardian archer, I don't know why, neither I know why did I make him blind.
Although he can not see anything, he has some ability to see those threating enemies who use magic.

Still didn't find a name for him, but that's another reason to call him the mysterious messenger of the lost ancient times.

Yes, Ezreal inspired me to create something similar.
