Demographics: There are presently 21,400,000 billion residents within The Temple of Sinners and the Second Layer of Hell. These consist of most known races within the PH verse.

Mass Energy: The Temple Of Sinners can mostly be attributed to Nizhuan because she was the one who had brought order, subjugation, and dominance within the second layer of hell following Míngjiè Zìyóu aggressive purge of all those who sought to overthrow the authority of her command. Therefore, throughout the one hundred and ten years of it's creation, Nizhuan focused on infusing a great amount of energy into it. And, since Nizhuan herself has, at max potency, enough energy to otherwise destroy a small planet, it's fair to assume given their reclusive years during this period that they would have stored enough energy to otherwise fuel a large scaled star and still have mounds of energy left over from the residue of hell and Za Koa.

Therefore, one can surmise that The Temple Of Sinner is held together by an astronomical amount of energy. Even more so within the core of it which contains the home of Liu, Nizhuan, Mingjie Ziyou and Xunaze. As core of this planet should have enough energy stored within it to fuel four average sized stars; one representing Liu, Nizhuan, Xunaze and Ziyou each. The core itself would have taken an additional seventy-six years to forge as they grew into their strength and continued to store away more of their energy without much interruption.

It should be noted that this energy is mostly utilized in order to keep the functions of their layer maintained. So it's often used for the purpose of defense, creating resources/equipment/tools and ensuring that their layer is stabilized. This is not to be abused or used for anything other than story or to go on the offense if someone is attempting to invade or attack them. And with that, staff can review everything that is generated from this mass of energy with a fine tooth and comb if they wish.

Ever-Expanding: The Realm Of The Temple Of Sinners is one that is ever-expanding. The reason for this is because they would clearly reach a logistical problem if this realm remained static. Therefore, Nizhuan sought out to divide the energy within the core of this planet towards slowly expanding with each year to make sure they had space to accommodate the ever rising number of the dead and damned within their layer of hell. Otherwise, they would become overpopulated and be unable to hold them.

Replication Clones: As stated previously, there are a large quantity of replicas of Nizhuan and Liu which reside within the current layer of hell. There are around one million of them and they are broken up as followed:

0-3: 1 0-4: 2 0-5: 5 1-1 through 1-3: 100 1-4 through 1-5: 100 2-1 through 2-3: 1,000 2-4 through 2-5: 10,000 3-1 through 3-3: 100,000 3-4 through 3-5: 500,000 4-1 through 4-2: 200,000 4-3 through 4-4: 180,000 While it is possible for some of these clones to travel outside of hell, there must be a sufficient purpose and reason for them to arrive. They cannot be done on a whim and there has to be a proper plot/story/urgency to summoning them. Otherwise, they are to remain within this layer of hell to be used for the purpose of keeping souls in line. There are many spirits which come into their realm and this type of enforcement is often sufficient to keep the mass of them in line.

Soul Judgement: It should be noted that those who die and enter into this realm of Hell are subject to the judgment of Liu or Nizhuan. That means they can judge deceased souls to go to heaven, hell, reincarnate, stagnate in the Soul Society or wherever else they need to go once they evaluate a spirit.

So, there has to be a system where they judge the mortality of the spirit. And this system is devised through their connection with the cosmos. They are able to tap into the karma of those deceased (it can also apply to the living, but that would require player permission) and pull up a "mortality index". This Index goes from 0 to 5; with 0 being pure and 5 being totally corrupt. These subjective determinations are based upon the reasons for their killings, the actions they took in their life, the positive and negative they've bestowed to the universe and other similar factors.

So, if they manage to get a "4-5" on a spirit, they will often send them to straight to their layer of hell or another. If it is 3-2? That is considered a gray area and they are subject to the Soul Society or reincarnation. If it's a 0-1, then chances are they will be sent to heaven. That is how Liu and Sichuan have broken it down for those spirits who come into their layer of hell.
