Canary is not human. It was once, but no more. His familiar face and form hide the thing that lives inside. His skin no longer protects flesh and bone beneath... that part of Canary is long gone. It is just a leathery vessel, a vase of human hide that keeps the secret inside.
Within this husk lies the dust of a falling star. Canary willingly consumed a potion brewed with cold iron from a falling star. He did not realize what the star was. It was not always a stone, nor did it simply fall. Someone cast it out of the night sky for commiting a crime no human will ever comprehend. The comet's form still held the malice and madness of this ancient evil. It had been cast out of heaven, falling since the time before the first man. When Canary invited it to live inside him, it cast Canary out. No one knows where Canary is falling to, but we all miss him.
Don't let him show you 'the screaming face of the sun'. You too will be changed, and not for the better.
