(I thought of some more things you might like to know.)

Races: The Realm is home to a number of strange beings, and it's hard to understand how they exactly came to be.

Oozai: We already went over them.

Deku: A bunch of plant people.

Booznians: Pale Amish people.

Giants: Look similar to the Booznians, but are extremely tall, and a one-man army as a toddler. The two leaders are actually Oozai-Giant Hybrids. (I lied about Will being the first. Caram was born before him, so that would make him the fourth.)

Law: The first King, Zai, created a number of strict laws during his million years of life. If any of them are broken, steep punishment shall be given out. Criminals in the Oozai Realm, if on the run, will have a bounty placed on their head to assist in the search and capture of said criminal.

Theft: 6 Months to a year in Jail.
Assault: 5-10 Years in prison.
Organized Crime: Mass Execution.
Murder: Execution.
Rape: 50 Years or Execution.
Attempted Murder: 50-100 Years in prison.
Treason: Exile.

Yuld: The typical form of currency in the Oozai Realm takes the form of purple bills and gold coins with a picture of Zai on one side, and a soul on the other. The highest amount is a 20,000 Yuld bill. Yuld is the equivalent of two Yen.

Countries: Despite being virtually endless, the Oozai Realm has been split up into several "countries" for the many Oozai factions that were created during Zai's time.

Oozai Kingdom: The center of the Realm. Mostly peaceful, but there are a few instances of conflict. Only has five restaurants.
Population: 1,500,000

Fustiroz: A small kingdom built by Koozai, the self-exiled King and brother of Zoozai. It's a quiet civilization, which is protected via soldiers created by Koozai and his magic painting ability.
Population: 80,000

Kirod: A vast jungle inhabited notably by the Deku tribe. The Oozai here are all green, and rely heavily on their physical potential rather than magical. They refuse to speak anything other than their native tongue, but can understand other languages. The leaders of this "kingdom" were a group of four Oozai Lords, but the youngest betrayed his brothers and sided with Gohma for power. Imor was born in Kirod, but left to master his true potential.
Population: 40,000

Hahvulon: The second-most dangerous place in the Oozai Realm. Located underground, the Oozai here are cannibalistic and spider-like, not afraid to consume other sentient races, other Oozai, or even each other. The main entrance is underneath the Oozai Lord's palace, and the three were instructed by the first King to prevent the horrors within from escaping.
Population: ???

Nilro Miiraad: An endless blizzard, where only two races can survive the cold. This land is inhabited by the Giants, who were instructed by Zai, who they respected and adored for his towering height, taller than them, to keep a close eye on the prison of Lokaal, making sure that no one attempts to release him.
Population: 900

Soul Power: Something Imor enjoys because it reminds him of DBZ. Whenever an Oozai powers up their magic, or vice versa, a translucent orb the same color of their soul appears. The bigger the orb, the stronger the Oozai. It was said that Zai's Soul Power was bigger than the capital.

CHECK: An innate ability skilled Oozai can use to see if others have killed before. Oozai who cannot use this power rely on machines invented by Dr. Proton to see specific statuses on living beings.

Reproduction: As mentioned in the first part, Oozai can reproduce with either male or female. But it is possible for an Oozai to reproduce asexually, like most slugs. When they are ready for a child, a single Oozai can use their own sperm cells to impregnate their womb. The gestation period takes at least 6 to 7 months, and the infant will come out in a red semitransparent egg, and said egg will hatch within 4 weeks. For most Oozai, childbirth, or "laying", is considered three times worse than Human birth, except for larger ones.

Biology-Part 2: Oozai can be born with a number of birth defects like the rest of us, like deformed limbs or mental illnesses. One condition they can have is an inability to produce natural sugar in their blood, and therefore must constantly consume sugary substances like candy, or just plain sugar to prevent serious issues. Caram is one of these unfortunate souls.

(Or would it be fortunate? I mean, you can have all the junk food you want and nobody will nag ya for it.)

Geography-Part 2: In certain areas in the Oozai Realm, there are geysers known as Magic Wells. As the name states, they are nearly endless supplies of magical energy. As they are rare, many Oozai guard and meditate inside them to become stronger.

Zai's Scroll: In the prologue, Pincher gave Will a scroll full of spells which Zai had made, discovered, and/or forbidden. Here's a few of them, which will appear in this story if they hadn't already.

Duplication: As the name suggest, it allows you to duplicate anything, and anyone. If the user uses the spell on themselves, their magic is split equally with each copy, and are completely obedient to the original. If a copy absorbs magic from a Well for example, and is dissipated, that new surplus of energy will be sent to the original. (A Naruto reference. Not even a huge fan, but got ideas mostly from that, as well as Soul Eater, obviously.)

Telepathy: The power to speak with others with your mind. Most can only use it a few meters from the desired individual, but Zoozai can do it from hundreds of kilometers away.

Summon: The power to bring any person or object to you, or somewhere else. In order to summon someone else to your location, you must first make a blood brother-type pact with them, willingly of course.

Soul-Link: A difficult spell to master, as you need a second person to use it. By making physical contact with someone close to you, your souls will be temporarily connected, your bodies will combine, and power boosted ten fold. The difficulty can be bypassed if the two are blood related, as they are permanently synced by default.

Mind Control: One of the many forbidden spells. This one involves striking the desired target through the heart via direct physical contact with a large amount of magic. If the spell works, the wound will heal, and the victim will be 100% obedient to the castor, signified by hot pink eyes. This spell can only be reversed by the victim being knocked unconscious.

Impure Progress: A technique were the user manages to "stockpile" their Exp for later use. When needed, the Oozai can channel their Execution Points in the form of screaming ghostly figures that spiral around them.

Size Manipulation: This spell allows you to alter your height, Zai invented it so that he can actually run his Kingdom without accidentally crushing it.

Clothes Beam: Instantly gives you or anyone who's hit by this any type of outfit they desire.

Orb of Void: A spell that creates multiple black spheres of concentrated Void. These orbs can be used to block any form of damage, but will eventually shatter once too much has been delt.

Black Cord of Fate: The final, and most frightening spell Zai created as the ultimate failsafe. The user must go into a defenseless stance for two minutes, channeling all of their magic into one spot. After it is charged, they can fire a black cable at any living being, truly linking their souls together. And because of this, the user will, if desired, commit suicide in order to kill their opponent if nothing else works.

Religion: Im the beginning, Oozai were known to pray to the Heart for good luck, but many have begun to believe that the God from Christianity was the person who created the stone, and by extension them. This was theorized by Pincher, who discovered the religion when he went to Earth as it was still in its infancy.

The Oozai Lords and their tribe worship a man with metal legs, and provide him with the yearly sacrifice of the worse sinners they've captured in their jungle.

The Oozai in Hahvulon do not worship any form of deity, as hunger is the only thing that drives them.

And finally, the Giants worship Vangas, the oldest one in the realm. His strength is said to be that of a thousand Giants in one, that he could lift a mountain over his head with a single pinky finger, while balancing on his big toes, each one on a unicycle. But he's very, VERY old now, and is just the average strength of 10½ Giants. You can guess how his children came to be. (Only one giant Oozai existed at the time.)

Soul Eater: As you have seen last chapter, characters from SE have been brought to the world of Svtfoe. The two have nothing in common, so why have I made this decision? This version I'm making will be just a tad bit darker (Except for the original having multi-dimensionsal genocide.), where many characters will be seen killing others.

Basically every character from Soul Eater coexist with the others, but won't be constantly seen, aside from the ones important to the story.

(All I got for now, really hope this one gets popular. I'm open to take advice and criticism on how to make this book better. I'm not like guys who block you, unlike a certain motomoto123456789, things between us went down a while back, but it was his choice.)
