Lewis and his glowing win VS Nico experiencing the Horrors™ (P2)

The Edea dimension's equivalent to the Chaos and Master Emeralds.

The origin of the crystals are unknown, only that they were around since at least during prehistoric times, and that they have played a key role in Edea's ecology and history. The crystals are a perpetual source of Quri, the energy found within all native Edean life. Each of the six crystal emits a different type of Quri, corresponding to the six main Edean types: Lightning, Ice, Fire, Chemical, Light, and Sound.

The amount of Quri released when in Active Form is deadly at close vicinity, so special equipment is required to handle them. The crystal's "core" glows brightly when active.

In Neutral Form, the crystals emit little to no Quri on their own. A certain amount of Quri can still be extracted, but nowhere near as powerful as when it is active. The crystals are safe to handle directly in this form. Their "cores" will be dark in this form.

Active and Neutral Forms

The Quri Crystals naturally move between Active and Neutral states over the course of years, or even decades.

The transition is similar to that of a wind-up toy:

A Neutral crystal gathers quri from its surroundings, slowly gaining energy until it is "fully winded". It then becomes Active, and the internal activity of the crystal causes it to produce large amounts of Quri.

Despite producing energy, The crystal cannot "feed" itself. And so, it naturally slows down over time due to losing inertia and becomes Neutral. It then needs to be rewinded.

It is possible to toggle them manually using the Null Prism (the Master Emerald equivalent).

There is an alternate, more egregious method. The one that was utilized during the Planetary War period: Gathering a enormous amount of Quri and blasting it directly into the crystal. This method is the equivalent of using an industrial drill to wind up a toy.
