An unknown fog spreads all over the world. When the fog begins to appear scary monsters, unknown items, and chaotic songs, fear suddenly spreads to everyone like a virus. Now people realize...the world is divided by the fog...but At the same time, the fog can let you go to other worlds. Will you step into the fog to start your journey?I had no choice because the fog had already engulfed me. When I walked out of the fog, I found myself in a strange forest, full of bright flowers on the ground, many long black trees covering the light, and ruins of a mythical white mansion. This world has arcane elements, bizarre creatures, magical items, and even eldritch deities. I start my journey, maybe I can find the way back home, or live in this world.
