In the beginning there was no such thing as World of Living. Creatures existed in peace and dissolved at the end of their existence. But after the Great Massacre creatures were in unrest, and they found themselves becoming living organisms in a new universe. They didn't retain their memories in that life and had their own purpose there. Initiators are still stuck in an endless loop of reincarnation in the World of Living. Now Creatures are transfered to the World of Living after "dying" in Seven Worlds, unless it is their time to stop their existence. A creature that's about to be sent to the World of Living is judged by three former Lords of three dark worlds(Hell, Sub Hell and Hyper Sub Hell) who are deciding what living being the creature will become and how many reincarnation cycles the creature is sentenced to.
