Infel Phira

Infel Phira (インフェル・ピラ, Inferu Pira), misromanized as "Infel Pira" in the official localization, is large sphere-shaped artifact that can be seen floating in the skies above the Second Tower of Ar tonelico. It's a very important piece of Lost Technology, which was created 400 years prior to the events of Ar tonelico II in an attempt to create Metafalica.

In the current days, it continues with one of the main roles it was built for: being the Song Servers for the IPD Reyvateils. Its name is in Hymmnos, and translates to "Seed of Love".

Its unique characteristics are: using an Hymmnos dialect unique to it, called the New Testament of Pastalie; being capable of creating and maintaining a landmass; and being able to change its form according to the commands given to it by the Maiden of Mio.

Structure
The normal form of Infel Phira has the shape of an sphere, surrounded by three rings, giving it the same Saturn-like appearance that the Shell of a Heart of the Land and Sol Marta have. The outer layer of the sphere is made by large number of blocks, which also are the main components of the rings. However, the rings and the main sphere themselves have a damaged appearance, which was caused due to attacks from the Divine Army. Supposedly, the main sphere also contains the Grathnode and Parameno rings that give it the ability of converting the Songs of the IPDs into Magic, but at the present time, there is no official confirmation on this.

Precedents
The history of Infel Phira began little after Jaza's theories were discovered and deciphered by a radical political faction of Metafalss. Given that the creation of Metafalica required the sacrifice of a Reyvateil to be completed, according to what Jaza had researched, the people abandoned the radicals, which, wanting to regain their support, began searching for a method that would allow them to try and create the paradise everyone yearned for without sacrificing anyone.

The method found was creating something that could be used as a substitute for the sacrifice that Jaza's EXEC_METAFALICA/. needed to accomplish its functions, and so, the Infel Phira Project was born. This version of Infel Phira was supposed to be only a mechanism for creating the land, so unlike the version that was built later on, this one didn't have any Song Server capabilities, and was entirely dependant on Sol Marta (and by extension, on the First Tower of Ar tonelico). However, all the initial attempts at building it never passed the First Stage, and ended in utter failure. Due to this, the Grand Bell decided to forget about this project, and leave it to fade away from history.

Grammul's Arrival
Then, a certain day, in 3258 AD, the Grand Bell made the announcement that the project would be restarted, thanks to a very special fact: an scientist, Dr. Grammul, was hired by them, because of the acceptation his Super Reyvateil Theory had gained among the general public. In there, it was suggested that Infel Phira should be a completely independant system from the First Tower, and use the Reyvateils that would be linked to it (the IPDs) as its main power source. And with that alone not being enough, Grammul also proposed to combine the powers of all the IPDs singing together into a single consciousness and a single song, which would be what would allow to fulfill the extremely high requirements for waveflow and spectrum required for EXEC_METAFALICA/., and to avoid sacrificing anyone.

However, the last part, the one about voiding the need for sacrifices, ended being a lie, since the IPD that would end up being the Administrator for Infel Phira (who is currently known by the title of Maiden of Mio) would end up being transmigrated into a Heart of the Land, and into the basis for the land. However, this part was never shown to the public, and due to it, the Grand Bell assembled a team of outstading engineers: Team Lakra, and after seven long years, the First Stage of Infel Phira was completed successfully.

The First IPD
The concept of the IPD Reyvateils naturally came together with the development of a separate Song Server from Ar tonelico, so they were created in parallel to Infel Phira's construction. So after many failed experiments and continued research, finally, the very first IPD, Infel, was transcribed to Infel Phira in 3291 AD. Once this experiment turned out to be successful, the Spectrum Gene that was used for Infel was implanted into other unborn Reyvateil gene-carrying girls, making it possible to change the server in which they depended from Ar tonelico to Infel Phira, and creating the IPD subclass of Reyvateils.

Thanks to this, the Grand Bell established that from that time onwards, there would be a second Maiden that would rule Metafalss, the Maiden of Mio, while the Maiden that already existed since nearly 300 years ago would be called the Maiden of Homura.

However, this atmosphere filled with happiness wouldn't last for much more time: a few years later, the fact that Metafalica would still need sacrifices to become a reality was leaked to the general public, and all of the support that Grammul had gathered went away in less one day. Not only that, also, Infel had already found and corrected all of the flaws that Grammul's theory had, discovering the existence of the Selfstabilizing Tesseractal Nuclear Loops, and basing the new theory for creating Metafalica in this. Due to both of these facts, and to his old age, Grammul was fired from the project, and Infel was appointed as the new head of the Metafalica and Infel Phira Projects.

Infel's Work
After obtaining the leadership of the Infel Phira Project, and creating successfully the Heart of the Land known as Metafalica-Alpha, she and her team began programming the Hymmnos dialect that would be exclusively used by Infel Phira: the New Testament of Pastalie. It was designed to take advantage of Infel Phira's lower instruction count and higher execution timing, allowing the IPDs to sing much faster and with a more powerful range of effect than the Reyvateils on Ar tonelico or Harvestasya would be able to attain. However, this doesn't mean that the other Hymmnos dialects wouldn't work in it, given that Infel Phira was also built with an emulation layer for every single Hymmnos word registered in Ar tonelico's Hymmno Server, allowing the IPDs to sing in any dialect they wish, but getting the best efficiency and power output from singing in New Testament of Pastalie.

Infel Phira's Completion
After all of the structural and programming work in Infel Phira was completed, Infel dedicated herself to streamline all of the process necessary for creating Metafalica into a single song: METHOD_METAFALICA/. This was the final difference between the theories that she and Grammul had established: instead of sacrificing the singer and turning her into a Heart of the Land, Infel's theory made it possible to create a Heart of the Land out from the combined singing of all the IPDs connected to Infel Phira, which would then be used by EXEC_METAFALICA/. to create the land.

On 3310, after much time of effort and investigation, Infel finished crafting and programming the Song, thus leading the Infel Phira Project to a succesful end. However, the history wouldn't end here...

The War Against the Goddess
Since when Infel and Nenesha tried singing Metafalica together, both Infel herself and the people committed the error of closing their hearts to each other, thus rendering METHOD_METAFALICA/. completely useless, and forcing Nenesha to extract power from Frelia to be able to sing EXEC_METAFALICA/. to the end. Due to this, Raki descended from Sol Marta, killed Nenesha to regain the D-Cellophane. Due to this, Infel declared war to the Goddess, and mobilized all of the IPDs to try and capture Frelia.

Infel Phira became an instrumental weapon for the humans during this period, given the huge amount of power that the Replekia Mode could release. Honestly speaking, without this power, they would most likely have been defeated by the Divine Army. However, Raki knew this, and while she never could destroy it, the Divine Armies under her command inflicted a great damage on the Song Server, killing a great number of IPDs due to the memory sectors where their Cosmospheres resided being destroyed, and destroying the emotional limiter that Infel Phira was equipped with.

After the War, it was agreed that Infel Phira would be shut down, and all of the data it contained would be erased, as per the conditions in the Hibernation Pact described. Infel Phira would stop being a Song Server, and become a lodging for the souls of the people of Metafalss once EXEC_HIBERNATION/. would be sung.

Modes
Due to its form changing capacity, Infel Phira is able of accomplishing a variety of functions thanks to its multiple Modes. Below is a description of each one of the Modes into which it can transform through the commands it receives from the Maiden of Mio:

Sarre Mode
The Normal Mode, in which Infel Phira remains for as long as it doesn't receive any commands from the Maiden of Mio.

This Mode allows all the Reyvateils to have their own individual consciousness, and according with this, it also keeps the Shared Consciousness Fields in a way in which they can't mingle with each other. In short, it gives the IPDs the same condition the Standard Reyvateils have whenever they access to Ar tonelico, and it's also the Mode under which Infel Phira and the IPDs were made. This Mode is also know by the alternate name of [Individual Consciousness Mode].
