#bioresonance

One of the earliest uses of the power that also comes across as it's most obvious use is as essentially mind reading or telepathy.

It's used by the Kolibris as a form of peacekeeping, rooting out dissenting thought, or detecting trouble before it reveals itself. We know that they can use it to communicate with others but is especially useful within the cadre. Through these units we also learn it can be used to create illusions, that it can be used to directly harm people, and that in universe it probably functions on a wavelength in some way as it's affected by the radio. A document on the Kolibris calls them the most bioresonantly capable Replika to be created, and while I don't necessarily doubt that's the case I don't think it's as straight forward as they are "the best" at bioresonance. This is because the of the Falkes. It's worth mentioning that these units as of the events of the game are still considered "prototypes" so it may mean they aren't being considered in what units are most bioresonantly capable, and upon their release would then take on that title from the Kolibris, but for the sake of argument I want to continue as if they are included in the comparison of capability.

According to Yuri Stern, Kolibris are incapable of telekinesis, a power that Falke on the other hand is clearly able to use. But on top of that Falke also appears to have the power to manifest both her spears and her halo at will. Prior to her awakening neither is anywhere to be found, and she also manifests the shields later. This contrasts the Kolibris who are only able to create illusions. (Falke likely can also create illusions, and communicate telepathically through her switching between appearing corrupted and normal, and also her calling corrupted Aras mid-fight, but we also see the Mynah do the same so there's not much proof in that. So if she can it's to a lesser degree). With that in mind it's very possible that Falke isn't so much better at bioresonance than the Kolibris, but rather is a savant in a different field of the power all together, possibly even multiple or all. And where the Kolibris are far more capable of utilizing the full range of power their field of bioresonance they command, Falke only scratches the surface of her own. Hers being the direct creation and manipulation of reality, hence why she is called a regarded as a god. Other feats Falke can be seen doing range from, using blasts of the power, which seem to take the form of orbs of space which appear manipulated in a way that looks similar to gravitational lensing (gravity will come up again later).

I've also seen it implied that the arena changes which occur during her fight are also an expression of her power to shape reality around her. This idea of her power being widely encompassing of the spectrum of bioresonance, but to a lesser degree is furthered by comparing her then to Ariane. She appears to have a far more vast command of the power if it is to be believed she is the reason for the cycle repeating ad infinitum. She even seems to trump the Kolibri's command as her power is attributed to have been the reason Elster's (And her own) memories were placed in Falke's mind. This is likely also the reason that the LSTR-S2301 was never commissioned as the power somehow rewound time (while also implanting the unit with the LSTR-512 memories and remaking her every time she dies in the facility... Sierpinski Elster stuff is weird, she could be a whole post on her own :/). A book found in the Itou bookstore also says that the power has been used to klimaform planets, and even create artificial gravity. In another place its stated that bioresonance is essential to Replika creation and without it the process is likely impossible. While the first two are vague in how the power is used, it is interesting that the power is essential for creating Replikas, as it means that its power of creation isn't limited to non-living things as Replikas are alive, and bioresonance is essential to make them that way. All of this together paints a rather clear picture that the scope of possible applications of bioresonance isn't only unknown in universe, but even speculatively it appears to have no limit at all. A sufficiently skilled bioresonant adept may be unstoppable with a free ticket to change reality however and whenever they like. The only limiting factor being, first their rarity, and two their supposed loyalties. We know these individuals are rare as there is special exception made to their discovery, and even rarer is their ability to use the power.

We know that their supposed loyalties may be a issue as the Nation very likely kills any with the power they don't think that can have perfect control over. As any who can command the power well and decides they don't want to bow to either the Nation or the Empire could very well become a problem for both. Therefore it makes sense why we are told they are arrested even if suspected of being able to control the power

Julia is probably dead btw, not mentioned, but we know somebody with the same last name was trespassing and died in interrogation.

Its possible that those allowed to live are given markings denoting their status, the forehead is clearly visible and would allow them to be kept track of. Something that feels rather fitting, considering the inspiration behind the game.

Out of all the characters you talk to, she's the only one who expresses the will to leave this accursed place.

Isa is like you, she's looking to go deeper to find someone she cares about

The Storch unit you meet in the security office is waiting for new orders and says she has no desire to abandon the place

Beo, the injured Mynah, is just waiting to die

Adler wants to stay and to stop you

Falke is too far gone, she's not herself anymore

The Star and Eule are so deep in the mines that they wouldn't be able to escape even if they wanted to. The Star is dying and I don't think the Eule will even retain the will to live once the Star is gone

The Kolibri is lost without its cadre and is just hiding in a room

So, did the first Star unit make it? Was she able to safely escape this nightmare of a time and place?
