After million years, you can gradually influence this world by will through dream. However, there are sober-minded people, the invesitgators, who spare no efforts to stop you from waking from darkness. Now it’s time to wake up and release your power to reign over the world. Because you are meant to be the chaos, the source of doom. Eventually, the real dominator will return!
