Somewhere in the universe lies a tiny irregular-shaped galaxy, which wasn't following the laws of the universe, not revolving around anything, not attracting any object nearby too. Even the biggest of the biggest black holes couldn't impact it even a tiny bit. It was just floating aimlessly all over the universe like a free traveler without any restrictions but at the same time, it was connected to every planet and star present in the universe.
This weird galaxy was the home to Gods, Angels, Immortals, Demons, and other spiritual beings. It is where Heaven and Hell exist. It is where the fate of every human will be decided. It is where the creation of life takes place. It is also where the souls return after they die. The most common term humans use to describe it is the Immortal Realm.
