Slaan has a inherent dislike for humans, blaming them for the rise of the Death god. Believing that the civilized world made them greedy and corrupt, eventually leading them to worship death for their own gains. Animals on the other hands are pure in Slaan's eyes. Their simple, humble creatures, living each day to the fullest. They do not care for fame, glory, riches... All that matters, all that should matter is survival.
