Notalium

Notalium is the most prevalent item throughout the entire game, and is crucial to Fisica's and Ritmo's journey to restore the world's life. They appear as glowing crystals of varying color.

## Properties

Notalium crystals are "sound energy [stored] in minerals". They have multiple uses such as:

* Powering mechanisms (such as the Mysterious stone pillars of Chapter 2).
* Temporarily protecting people from the effects of Al Niente, when worn as accessories (such as Fisica's pendant, Rossa's earrings).
* Restoring color, weather, plant life and animal life to an area affected by Al Niente once tuned by a Notalium Tuner.
* Capable of storing one's own life energy.
* Controlling small organisms.

Notalium also exist in one of two states: ordered and disordered. When disordered, the power inside a crystal becomes inactive, which is why places in the game can have these minerals in them, yet still be under Al Niente's effects. Disordered Notalium is also unusable for any of the purposes above, but ordered crystals are not always safe to be around. Some larger Notalium crystals (such as those in the Bell Tower, in the device in cyanine, and in the Pipe Organ) have too much energy in them to be stable and require further tuning in order to be quieted. If this kind of Notalium is not stabilized, structures surrounding them may collapse.

Notalium is collected through playing songs and completing challenges. However, in Chapter F's "Special Specimen Room" in the Notalium Administration headquarters, there are spherical pieces of Notalium whose "shape, brightness and formation are all different from the typical pieces" according to Fisica. She wonders if there are more crystals like these waiting to be discovered somewhere.

## History

Notalium dates back centuries, before the disaster of Al Niente began.

Its inventors were a woman named Ena and her husband Halpas. An entire field of science was created around these crystals. These crystals were the embodiment of sound, where control over the crystals was control over the object itself. As this technology spread across the world, countries incited several wars over its power. This angered Halpas, who argued that this power should only be kept to him and his wife alone. Over time, Ena's exposure to Notalium energy had put her body under immense strain which caused her to collapse. Before she did so, she created a crystal that was capable of holding her own life energy. This crystal is referred to as the "Notalium of Life".

People used to know how to make more Notalium, but this method has been forgotten over the ages. Still, scientists like Fisica can come across these minerals easily in order to do research, and things such as Notalium Tuners can still be manufactured seeing as Fisica built one using documents from the Notalium Administration.

The Notalium Administration has tasked Fisica and Ritmo with restoring the world from the effects of Al Niente, but their true intentions are unknown.

Currently, the Notalium Administration is in charge of storing and distributing these crystals.

## In Gameplay

Notalium is the most common item in the game. Completing song challenges awards the player with Notalium crystals. The player can check how many crystals they have acquired in map view or by checking their stats. The Notalium collected will not impact the story, though it provides a boost in the amount of Stabilized Sound the player receives after playing a song.

If the player has acquired at least 300 Notalium crystals, they can use Stabilized Sound to unlock a chart's Master difficulty immediately.
