Nex Exitium

Nex Exitium are exclusive to the EvoBlaze Possibility and are a highly-advanced class of Ars, which are classified as a form of Ars Volo Magus, being a weapon operating off the wielder’s desires to bring harm. 
They were utilized by the Genesis Destroyers and some Prime Fields in the Third War, and currently are used by the Sequence Destroyers current division. They are primarily featured in Control Sequence with the former weapons being featured in the prequel, Genesis Destruction. 
==Basic Information==
Nex Exitium are dangerous weapons that are a set of transformative Ars and will alter their form to suit its wielder, much like a Grimoire can and were smelted in various contained and controlled processes. Their primary purpose is stated to be for defense against powerful Irregularities in the world or even individuals who are directly connected to the Boundary. 
Each Exitium is run by a condensed core similar to a Seithr Core in design, and they receive their strength from a much larger source, however this source is kept out of the public’s knowledge by the SIA. Exitium all contain the capabilities to destroy and decay matter converting them into the substance of Seithr--essentially ‘erasing’ the victim provided the user is strong enough. Oddly enough, some Exitium wounds can lead to Black Corrosion as well. Their capabilities to snuff out existence via reduction to Seithr and energy is known as 'Erasure'. 
Although there are many replications of Exitium for the uses of the SIA's Destroyers, the original models were much scarcer, Leviathan being one such design. Even though they were redesigned and made synthetic, the demand of resources for them is still high, and there are few who hold the aptitude to wield such powerful weapons. 
Some Exitium are known to have some form of sentience and the weapons had developed wills of their own which have an overwhelmingly strong 'hunger' for something, latching to this in their wielder's souls. If the wielder cannot sate that hunger, the weapon will take it on its own. This strange trait can cause discord with their wielders, resulting in severe costs to them in either their mind soul or body. When an individual and their Exitium are in perfected synchronicity, the cost is negated and this hunger becomes their own power. The only known Destroyer to have achieved this is Akuhei and Leviathan. 
==History==
The Nex Exitium are known to originate from the Third War, though the concept of such weaponry that operated on the desires of a individual dates back to during the time of the system's early designs. However, Exitium were considered at the time when humanity was struggling to deal with the excessive amount of deadly Seithr Irregularities, as a stronger set of such weapons of the Volo Magus class were required to keep up with their ever changing foes. How such technology and power was implemented by the system was not shared with many, as they were weaponry managed by the Izanagi Agency while they were still active. However, weapons like the infamous Leviathan were utilized during the Third War as part of an on-going project alongside Boundary Fragment and Cores to look into humanity's options of weaponry to use against their foes during the Third War and to bring a swift end to it to prevent further calamities with the Rogue Sector's constant attacks among other disturbances. Such projects were overseen by the Izanagi Agency and Exitium class weapons were one design to come from the studies of the Boundary Artifact Materialization Records. Supposedly there were other designs besides them, but they were all experimental at best. 
These Exitium were often given to individuals who were not human, or one infected with Black Corrosion or unstable Drives alongside the crystallized objects called Boundary Fragments. This meant many Prime Fields and artificial living being were considered for these trial periods with the weaponry. 
After the Third War ended, the Exitium were the only recorded success from these projects, and were implemented into the NOS’ military in a more controlled manner. Lukain, having had several experiences with individuals who wielded such weapons was part of the decision to continue on with a modified idea of it, leading to the synthetic Exitium for their own division of destroyers connected with the system, leading to the Sequence Destroyers, the individuals who would be entrusted with these weapons. 
The only known original Nex Exitium is Leviathan, most of Leviathan’s class were destroyed or repurposed into other projects, as the requirements for making use of the original units were far too dangerous or simply impossible to replicate successfully beyond Leviathan which was directly inherited by Yamaorochi's successor. The synthetic designs were then considered the most viable and appropriate for the system to make use of against the continued threat of Destructive Irregularities. These synthetic models were restrained and adjusted in various ways to suit the Boundary Management System's requirements. 
As of Control Sequence, they’ve largely become a topic of disdain toward the World Order by other organizations who view them as sinful weaponry and the necessity of them is debated constantly. 
==Abilities==
Each Exitium is unique to the wielder, although, it is possible to find ones with similar style. They are adaptive weaponry and transformative Ars, typically swapping between two forms. This is mainly because of the connection to the mind, body, and soul the weapon makes, taking the idea of how the wielder most feels comfortable fighting and manifests itself into that form.
Built to enhance ones Drive, generate a connection between the user and the Boundary in a controlled manner, and allow one to wield that power seamlessly, few weapons can outmatch the Exitium. By latching to the user's inner desires and emotions, the weapon enhances these negative aspects of an individual, using it to feed itself and the user to grant a flow of power. 
Perhaps the most iconic thing about the Exitium is that they erase existence. It first destroys the mind of its target, then damages the soul, and finally erases the bodily existence by reducing it to Seithr Scourge. Depending on the Exitium, more or less damage will be done to soul or mind before it can convert the full body to nothingness. In very rare cases a soul may cling to existence even after erasure, such is a case for beings like Koyoto. 
They're considered something of wicked instruments and are designed with a will of destruction, due to the infernal core in their body. If its wielder isn't careful it'll easily shape them to its whim. If their will coincides with the wielder's desires and psyche their power will harmonize and increase. However, if it clashes it can result in the Exitium's will taking over or worse if they're not strong enough, resulting in many negative effects. Due to their overwhelming desires they often overpower their wielders and an Exitium tends to focus on a negative aspect shown by the wielder and intensify it beyond the point of any real control. Even so, an Exitium's true strength comes out when its harmonized with its wielder, though few have accomplished this.

==Trivia==
*Nex Exitium means 'Death Destruction'. Referring to their affinity to both. Both can also be likened to a form of death, as Nex can also mean Violent slaughter or Murder, while Exitium can mean Doom. 
*The main protagonist of the series Nex shares his name with these weapons. Oddly enough they both have the capability to destroy existence, however Nex does so in a different manner.
