The concept of overlapping domains can be understood quite simply. It is comparable to a solar system, where the Titan domain acts as the sun, holding all the other domains together. However, in this domain system, a domain, which represents a world, can appear or vanish, switch areas, and its size can be controlled within certain limits. Similar to four galaxies within a single giant Galaxy.
Aleazm's domain, has the one with the most outing experience among the others. It is carried with him when he is not at home.
Just like in a solar system or a galaxy, each world is different yet similar. The same applies to domains. They are all formed in a similar manner but differ in some aspects. Most domains are so alike that the only distinguishing factors are their size and nature.
It isn't impossible to leave one's domain in a spot. Even if someone is physically distant, they can still control their domain, much like a king can govern a nation even when not present. However, there are certain limitations. Orders given from afar may take time to reach the intended destination and could be interrupted, tampered with, or have their content changed by enemies along the way. This is unlike the situation where the king is physically present in his kingdom, where he has more immediate control and influence.
Additionally, the further one is from their domain, the more energy is required to sustain its existence. There is also a time delay, which can be a matter of seconds depending on the distance between the person and their domain, but this might as well be giving the enemies years to plan.
A domain refers to the act of creating a kingdom or a world. The process of forming a domain begins at the Juda: pseudo-giant level, and it is crucial for advancement. To comprehend the concept of a domain, one must first understand 'Nature or element.' This refers to the elements that an individual can control from birth, as every living being is born with a nature. It is possible for someone to have multiple natures.
Your nature is the foundation of any domain, representing various elements such as fire, water, earth, lava, and air. Nature comes in countless forms, but when compared to the number of living things in a single planet, a solar system, or a galaxy, the variations of nature are limited. Therefore, when two users with similar domains and energy levels face off, the winner is determined by their skill, creativity, and possession of a TAMA.
There are two methods of creating a domain. The first involves using your energy to create it, while the second entails stealing resources from the world to form your domain. The latter method is preferred by most beings in existence. In contrast, when you fight using energy that is not from your domain or when it is inactive, there is a risk of being harmed by your own attacks. However, attacks produced from your active domain pose no harm to you.
The latter method, unlike the first, involves a water nature user going to a lake to transform it into their domain. In this process, they would need to continuously refine the lake using their energy, soul power, and mental strength. This refinement continues until the user and the lake's energy become indistinguishable from each other. However, this task can be quite demanding and may take several days, months, or even years to accomplish.
