*Main principle: the Mind influences the Body and the Body influences the Mind, e.g the Spiritual influences the Material, and the Material influences the Spiritual

*Exploited by the Mind Science, which produces Equations => spiritual products, which uses scientific formulas to infuence the Material (but watch out, as stated before, the Material can also influence the Spiritual), could be seen as alchemy

*Equations are appliable with the mind, requires a clear mind and great concentration. Because of that, there are specialists made specifically on applying Equations on stuff (also possibility of having Machines do it more efficiently, but only if the technology is efficient and with the right materials)

*Making Equations requires great scientific knowledge, which means there are scientists and engineers.

*Applying an Equation on a living being gives sigils around the pupils, they're unique for each individual in both form and color, but can also change depending on personnality changes or extreme emotions. These equations are fueled by spiritual energy, which could be body energy (like tools used by workers), emotional energy (which is used by Patrollers, where the output are used as super powers, think Lantern rings but they're straight super powers instead of constructs), thought energy (like for scientists or students wanting to boost their faculties) => possibility of Equations using more than one type of energy source.
	=>Side effect where if a person wearing an Equation is suffering through a trauma or abandons themselves to their emotions, the spiritual energy takes over the user, transforming them into a monster, dubbed a Demon (think of it like the corrupted gems from Steven Universe but instead of being from the fallout of a nuke it's from mental illnesses and extreme emotions)

*A person's mind is structured as a core and two layers:
	-the iD, where pulsions and emotions are held. it could pierce through layers if not contained or if the Mind is facing a trauma/is attacked
	-the Reason, a person's Self and common sense. Struggles between the iD's wantings and the Conscience's orders, as well as the outside world. It could crack on either of them (see Side effects of Equations above, which could still happen even without wearing an Equation, but not so drastically)
	-the Conscience, judges the Self from morals, social expectations, and its desire to make the Mind Perfect. It guides the Self, and punishes it with guilt/anxiety/feeling of inferiority.

*Brain => Mind's vessel to exist on the Material plane, with the Body being its way of interacting with it. But because of it, the Mind is at the mercy of the Material, but the Mind can train itself to face against those influences and attacks.

*Equation-based phenomenons can happen naturally (could range from natural happenings like forest fires to paranormal-like happenings)

*Factions:
	-Empire: current political power, has a police/military force in the form of Patrollers being ordered by Generals.

		Patroller ranks:
			*Apprentice: after years of studying, a student is taken on the field under the wing of a Captain to perform a certain number of missions until the Captain seems fit the Apprentice is good enough to becomes a fully fledged Patroller.
			*Patroller: individual investigator. Work to investigate crimes and mysteries/anomalies. As they are assigned to a group supervised by a Captain, depending on the mission they can form said group (though the number of members can change depending on the mission)
			*Knight: Elite Patrollers, usually working on the outskirts of the Empire to fight against powerful beasts and other anomalies that could threaten the Empire. They also provide supplies in the form of Food and Minerals.
			*Captain: Supervises a group of Patrollers/Knights assigned to them, responds to a Colonel's orders.
			*Colonel: Orders Captains around, gives them Missions.
			*General: Supervises and orders around everyone on the field.

	-Criminals: Most of the time divided, lots of little groups doing their own crimes like robberies, traffic, and so on.
	-Vigilantes: So-called heroes who wants to make justice without the Law limiting them. Powerful and secretive, most of them are working for a good cause, but some of the members have their own agenda, some are even extremists
	-Group ideolizing the iD as the one true form of the Mind => anarchists, extremists, "demonists"
	-Group ideolizing the Conscience, with the belief of it submitting/vanishing the Reason over it, bringing a Perfect Mind => elisists and aristocrats
	-Group ideolizing the Reason as the one true form of the Mind, wanting it not to be influenced by the iD or the Conscience
	-Transhumanists, don't want the Body to influence the Mind, consider the flesh weak because it influences the Mind => looking for Technology to bypass that, as they think a unnatural Body will not be influenced by the outside world, if not as easily, as well as advantages like eternal life and machine upgrades.
