Grades of Iserialogy

Iserialogy comes in four distinct grades, which is defined by the grade of Iserial Energy used to perform it.

It practice, the majority of people is unaware of this subdivision since in the majority of worlds, the only kinds of Iserialogy actively being practised are Primary and Secondary Iserialogy, which are often not perceived as related concepts.

## Primary Iserialogy

*Main article: Primary Iserialogy*

Colloquially also known as spiritual magic. Primary Iserialogy has no element and can't directly affect the Material Plane. It is used mostly for divination, and while it can be useful, it is also the least reliable and least powerful grade of Iserialogy.

However, Primary Iserialogy *can* affect the Spiritual Plane. Apart from Primary Iserialogy, only Quaternary Iserialogy is capable of that. Its possibilities are limited, but include such feats as communicating and manipulate Spirits, given that they are either willing or the Iserialogist is sufficiently powerful. As such, Primary Iserialogy is important for Summoners, and people with a talent for Summoning will usually have a talent for Primary Iserialogy as well.

## Secondary Iserialogy

*Main article: Secondary Iserialogy*

Colloquially also known as elemental magic. This is by far the most abundantly used grade of Iserialogy, making up for over 90% of the total use of Iserialogy in any given world. Secondary Iserialogy is the only type of Iserialogy that directly uses elements other than Minayero.

Secondary Iserialogy, broadly spoken, revolves around the manipulation of energy and matter, Although it can't directly create or destroy matter, the fact that it can convert matter to energy (including Iserial Energy) and vice versa still makes it possible to generate matter out of "thin air" or reduce something "to nothing".

## Tertiary Iserialogy

*Main Article: Tertiary Iserialogy*

Colloquially also known as virtual magic. This type of Iserialogy is essential for creating self-sustaining Iserialogies such as Iserial Programs, Golems or artificial Iserial Creatures. Tertiary Iserialogy can indirectly incorporate elements by interfacing with Secondary or even Quaternary Iserialogy.

In fact, Tertiary Iserialogy is rarely if ever used on its own. Rather, it is used to imbue existing Iserialogy with autonomous behaviour that will be sustained even if the caster does not actively control it. All other Grades of Iserialogy require the caster to actively sustain and control them, while Tertiary Iserialogy will, if correctly woven, persist for an extended period of time or even indefinitely, performing a set of operations either linearly or repetitively.

## Quaternary Iserialogy

*Main Article: Quaternary Iserialogy*

Colloquially also known as divine magic. This grade of Iserialogy exclusively uses the element of Minayero and is mostly only used by Deities, since the use of Minayero by Mortals always ends up destroying the user due to the backlash caused by the Quaternary Iserial Energy.

Unlike the three other Grades of Iserialogy, Quaternary Iserialogy can't be learned. Instead, Deities are granted an intuitive understanding of it during their ascension. Mortals meanwhile can use Quaternary Iserialogy only in extreme situations where they have a very strong desire to achieve a certain goal even if it means sacrificing their lives. The mechanism by which this dubious boon is granted to Mortals is not fully understood, but it seems reasonable to assume that The Ancient or Fate are involved in it.
