Not only is the demon world inhabited by demons, but there are monsters that also reside deep within the abyss of the demon world. They are still considered beings of the demon world and ruled over as such. Though their intelligence is not as high as the demons, many are recruited into the demon forces for their excellent fighting abilities.
Navarus is from a species of spider monsters that reside in the abyss. He is able to block the enemy's attack with his solid shell and capture prey using his webbing. Due to his long life, there have been unconfirmed reports that he may be immortal. As a result of his strong magical resonance, he will sometimes leave this dimension when a summoning ceremony is proceeding in another dimension.
