The term "extra dimensions" is often used in physics to refer to dimensions beyond the four dimensions (three spatial dimensions and one temporal dimension) that we experience in our universe.
In theories such as string theory and brane theory, it is postulated that there exist additional dimensions that are compactified and not directly observable at our energy and size scales. According to these theories, the universe we live in may be a three-dimensional subspace (a "brane") embedded in a space with extra dimensions, often referred to as the "bulk" or "dimensional vacuum."
The dimensional vacuum is a region of spacetime where there is no matter or physical fields, but it may contain information about the properties of the extra dimensions and the interactions that take place within them. Understanding the dimensional vacuum is important in attempting to comprehend the fundamental nature of reality and reconcile quantum theory with the theory of gravity.
Suddenly, a humanoid being made of light appeared out of nowhere.
"It's time, isn't it, Kaos?"
"Yes, he won't wait any longer. Azathoth is stronger than us, but together we have a chance." A being with a chaotic form that constantly changed shape and color appeared out of nowhere. "Where are the others?"
"Brahma is meditating, Enki is coming, and Emir too," Yahweh replied. "Cronos?"
"I don't know. My son disappears when he wants and appears in the same way," Kaos said. "He created abominations that are almost on our power level. We have to stop him before this gets out of control!" Kaos spoke with a deep voice that caused dimensional distortions so strong that even a god capable of destroying an entire universe would die instantly.
"I know," Yahweh, who is almost always calm, said with a calm voice. But if you pay attention, you can notice that he was not calm after all, since he created this reality.
"What if we ask for help from the Council of Dragon Gods?" Kaos suggested.
"They won't accept it without something in return," Yahweh replied. "But if we manage to speak with him, perhaps we have a chance of victory."
"Him?" Kaos asked. "Who?"
"The Celestial Dragon, the Star Forger...
