In this world, there are two primary races on Earth: Humans, and Monsters. Monsters often resemble animals of some sort, although they are commonly humanoid, and it is not uncommon to see a bipedal monster that doesn't resemble an animal. Humans, are, well... Humans. There are also these things called Souls. Humans have Souls, with seven primary traits, which change the color of the soul: Justice (yellow), Bravery (Orange), Patience (Teal), Kindness (Green), Integrity (Blue), Perseverance (Purple), and Determination (Red). Although the primary traits often show the most predominant trait of a human's personality, all seven traits are required to be present in a Soul for it to be considered truly 'human'. Monsters have Souls as well, although they are white. While it is theorized that Monster Souls represent Hope, this theory has not been proven yet.

Only a soul that originates from a monster can use Magic.

There are several elements to Monster Magic, for example, [insert character here] can use [insert magic type here] magic while [insert character here] can use [insert magic type here] magic.

Human-Monster offspring is possible, and it can have two results: A Mage, or a Boss Monster. A mage is a unique (And very rare) Human that is born with a Monster SOUL, and can use Monster Magic, while having all human SOUL traits. A Boss Monster is the much more common outcome, which is a Monster with a SOUL that has 1-6 of the human SOUL traits. A Boss Monster is stronger than a regular Monster, but a Mage is stronger than a Boss Monster. A Boss Monster does not require a human parent, only that their SOUL has a human SOUL trait, meaning that a Boss Monster SOUL can be created via the injection of a human SOUL trait.

When a being with a SOUL dies, it's SOUL is shattered instantly. There are three exceptions to this: Boss Monster SOULs, which remain intact for roughly 15 Seconds after death before shattering, Mage SOULs, which remain intact for several minutes after death, and Human SOULs with the primary trait of Determination, which break in half before shattering. It is important to note that, in rare cases, a Determination SOUL may re-fuse after breaking due to it's owner's willpower, preventing the death of it's owner.

When a monster dies, it's body turns to dust.

SOUls can be transplanted by Surgery, but this is only done as a last resort due to the risk. The compatibility of a SOUL and it's recipient depends on the predominant trait of the recipient's SOUL before the transplant. Differing traits are incompatible, while similar traits (Such as Perseverance and Determination, Justice and Bravery etc.) will be risky at worst, and uncomfortable at best.

Humans with a SOUL of Determination, or other beings with a large concentration of the Determination trait, such as [insert character(s) with DT here], can use Save, Load, and Reset.

Saving is the act of setting a checkpoint in time, and Loading is the act of returning to said checkpoint. Resetting is the act of returning to a pre-set, uncontrollable point, and erasing all saves made after the point that one returns to via reset. A reset point is usually decided by important points in time, such as one's birthday, or the aftermath of a traumatic event of some kind.

Only beings with the Determination trait can remember what happened before a reset. The more concentrated their Determination, the clearer they can remember. The being who initiated the reset will always remember what happened before it, no matter the concentration of their Determination.

When someone kills a living being, they gain EXP. If someone gets enough EXP, their LV increases. When someone's LV increases, they gain more ATK and DEF.

The more ATK someone has, the easier it is for them to hurt people. The more DEF someone has, the harder it is for them to be hurt.

Gaining LV slowly grants trace amounts of Determination.

The higher LV someone has, the more distant and emotionless they become, as they slowly become psychopathic.

LV and EXP do not persist between RESETs, and are both reset to the level they where when the user last SAVED when the user LOADs.

SAVE, LOAD and RESET appear as rectangular golden buttons with the names of each action on them. SAVE and LOAD can only be accessed at Save Points, which are golden glowing four-pointed rotating stars that only beings with a high concentration of Determination can see and interact with.

And now for some optional meta info:

This 'world' is actually one of millions. There are alternate timelines adjacent to this one, where things occurred slightly differently. Maybe the difference is as small as someone choosing a different breakfast, or as big as a nuclear apocalypse. Certain alternate timelines, or AT's for short can result in beings gaining immense amounts of power, or escaping their own timeline. These beings, specifically the ones that escape their own timeline, are known as Outcodes.

This world, like all of it's alternate timelines, is also made of code. Every single step, every single breath, and every mechanic of biology is simulated through lines upon lines of ones and zeroes. Certain powerful beings can manipulate this code to create universe-ending attacks, or completely erase beings made of code. Most, if not all beings able to manipulate code are not made of code.

This world, and all timelines connected to it, are a part of a large, inter-connected network known as the Multiverse. Every universe contained within the Multiverse is similar to one 'original universe' in one way or another, but is different in a way that couldn't have happened by chance or choice, for example, one universe could have gravity set to '1', as it was originally, whilst another could have 2x the gravity. The most common outcome for these 'alternate universes' or AU's for short is either important people taking different important roles or having their personalities changed on a fundamental level, or both.

All of this is best put in the 'scenario' of your bot instead of the personality. Personality should be reserved for PERSONALITY, and the abilities of said character, which may relate to the Scenario.

Human, I remember you're time here was I hope it good.
