The fallen {The one who returns from the shadows into the light}

I do not know what exactly I should explain, but I think I will only explain the power system and a few things about the world.But before we begin, I must warn you that some parts may contain spoilers for future events, so I will place above each explanation the word "Spoiler" or "Major Spoiler" so you can notice it… although you probably will not understand a single word from those spoilers, and honestly I do not even know why I call them spoilers… but anyway.The important thing…The Power System: Resonance — "Arcada".Arcada is the raw substance of the universe in this world. It exists in everything, even in the air, and it constantly vibrates. From this constant vibration came the name "Resonance".Arcada has several evolutions, each different in abilities, development methods, and the resources required to evolve.Arcada: the first stage. It is awakened by opening the magical pores, which can be opened through magical potions, exposure to the resonance of another user, or through shock. From that moment the absorption process begins. Of course, Arcada itself is a deadly poison, so it must be purified through the pores of the soul, but I will not go deeper into that explanation for now.Arcada Advantages — or in other words, the power levels of Arcada.The levels are generally divided as follows: Level Fifteen… Fourteen… Thirteen… and so on… until Level Zero.Each group has its own title and belongs to a specific stage of evolution.More precisely: Levels 15, 14, 13, 12, 11, and 10 all belong to Arcada and their users are known as "The Composers".Before moving to the next evolution, you must know that every level of Arcada evolution passes through several phases. For example, Level Fifteen is divided into: Beginner → Expert → Intermediate Expert → Advanced Expert → Master → then Level Fourteen.Requirements: Five Atorin Layers.I will explain those later.The second and third evolutions are Rikada and Oranava.I intended to explain them, but things are complicated to describe, especially since Arcada itself is not yet fully understood, so instead… here are the classifications of monsters.Serinava Beast — One Atorin Core.Cryonava Beast — Two Cores.Narionava Beast — Three Cores.Darionava Beast — Four Cores.Catastrophe Beast — Five Cores.Legendary Beast — Six Cores.Primordial Legendary Beast — Unknown.No further explanation.What remains are the places and the weapons. I will only mention their names.Magical Locations: Echoes.{Major Spoiler.}Dimensional Rifts — like the one possessed by the King of Nightmares. and {eraraka}Major Spoiler after Volume Six. and tow Weapons:Ranos — weapons that possess a strong resonance within them, such as the sword "Freyr", the weapon of Kyle Leonhart. Almost all weapons fall into this category except a rare few.Ancient Vardius — weapons with extraordinary powers and terrifying abilities that make them nearly unstoppable, yet they can destroy anyone who tries to claim them. They are the ones who choose their master, and you cannot declare yourself their master by will alone. Examples include the swords "Haze" and "Berkshael".As I said, here is the simplified power structure:Arcada evolves into Rikada.Rikada evolves into Oranava.From Arcada comes Atorin.Atorin is divided into layers.Those layers carry special traits called Frequencies.Types of fighters and people in general:Mages.Warriors.Healers.Seers.Battle Mages.And many more things that will appear throughout the story and be explained better over time.As for the worlds:There are three main worlds and three sub-worlds.The main worlds are: The Upper World, The Middle World, and The Lower World.The sub-worlds are: The Nightmare World, The Dream World, and The Abyss World.Spoiler after Volume Twelve.Each world has its own entities and rulers, and all follow a single "Supreme Path".Among them… "{the Fallen Path.}"
