Compendium

As the name suggests, this chapter is a compendium of knowledge that is related to the Magus Universe. Please note that this information will gradually be revealed as the story moves forward. With that said, this will contain spoilers, so read at your own risk.

First things first, let's talk about the magic system.

Mana is the ethereal fabric that runs throughout the universe, touching every corner of its existence. There are two ways Magi access the mana in their surroundings and tap into its magical potential:

External Mana System - Manipulating mana to achieve desired effects. Can be categorized into two: Magic Spells and Magic Combat (fusing physical combat with mana).

Internal Mana System - Extracting mana from the surroundings and subsequently elevating one's essence, resulting in strengthening oneself and advancing through the ranks. Further categorized into two: Body Enhancement and Mana Extraction.

Aptitude - Every person who is born with the ability to spell-cast has an aptitude grade. Essentially, one's aptitude determines how far one can advance in their path. The higher a Magus' aptitude, the greater mana reserves they have, and the faster their mana replenishment is.

Aptitude can be classified into five grades - A, B, C, D, and E. There is, however, another grade that very few people know about. People who are born with this grade are so rare in the universe that their existence can be called a miracle. They are known as S-grade talents, a.k.a someone who is loved by mana.

Now, let's get into the 8 Schools of Magic.

Warding - It focuses on protective, sealing, and defensive magic.

Summoning - It calls forth creatures, objects, and magical effects, and creates extra-dimensional space.

Divination - Users can see the future, gain insights, and uncover hidden information.

Enchantment - It focuses on manipulating minds, and influencing thoughts and actions. 

Invocation - It focuses on harnessing and manipulating raw magical energy to create damaging effects.

Illusion - Users can create sensory illusions and manipulate one's perception to deceive and mystify.

Necromancy - This school deals with life and death, manipulating life force, communing with spirits, and raising the dead.

Alteration - This school focuses on changing and transforming the properties of objects and creatures.

How does a Magus cast a spell? The casting of spells requires three magical components. Some require one, some require two, while others require all three. The three components are as follows:

Model Component - It requires a Magus to construct a spell model (magic circle) with their spiritual power, and then inject the spell model with their mana to cast spells. [Note: spiritual power is the energy generated by the soul]

Physical Component - It requires the Magus to weave finger/hand motions to cast spells. 

Material Component - It requires the Magus to sacrifice the required material to cast spells.

Alright, then, here comes the power system. I won't be disclosing all the ranks for obvious reasons. Just the ones that have been covered till the last privilege chapter will be displayed here. I'll keep adding details as the story progresses.

Mana Foundation - Has five minor stages (Flesh, Muscles, Bones, Organs, Neural). Mana washes the whole body of the Magus in that specific order. 

Two prerequisites are needed to advance to the next stage - formation of the spirit sea and complete establishment of mana channels.

Lifespan: 100-150 years.

Mana Liquefaction - Pure energy flows through the mana channels and condenses in the stomach region. The mana is in a gaseous state and is disorderly in manner. In this rank, the mana capacity increases and becomes more potent.

Lifespan: 200-300 years.
