Having been cast into the bowels of hell, Lucifer transformed it to reflect the evil intentions in his heart and declared himself the ruler. There, he tricks both man and beast into succumbing to temptations and makes them his slaves.
From Latin Lucifer translates as "light-bringing; the morning star, the planet Venus". Lucifer was an angel close to god. But he fell and lead an upraise against god and heaven with other fallen angels who followed him. In Christian tradition considered as ruler of Hell and personification of sin. Nowadays Lucifer is one of numerous names of the Devil.
