Book of Infernal Demons
"An enigmatic raven-black bird shrouded in the mysteries of the sky. Ever curious, Malphas has filled itself with all the world's knowledge and mysteries. However, this same curiosity has led to a rather brutal demeanor, causing the bird to tear those it encounters to shreds with its sharp beak and razor-like talons."
