For the first time, Arthea felt there was no limitation on what she could do, no restriction to stop her and she began to discover new techniques to harness her powers. While inside the oblivion realm, Zian invites him to take a peek at life in another world. Surprisingly, not all worlds have life, some worlds failed to develop and turned into a wasteland, some worlds were covered in ice while others became dry and barren deserts but there are also worlds filled with vile monsters that eat each other to survive.
According to Zian, these 'failed' worlds were simply abandoned by their creators and left like that for the Millennium without it being clear what they plan to do with the worlds, nevertheless, it was his job to make sure that all those worlds do not interfere with each other, therefore he prohibited to involve with the affairs in each other's world even though there was a situation he allows to make an exception as long his action didn't affect those world.
