The Rainbow Crystal is a long contested over artifact, known to cause harm to the environment around it as it sucks energy out of the earth to power whatever spells its user desires. It is located at the top of Mt. Dybla, underneath it lies the Rainbow Energy Chamber, and further below it, the Neko Reserve. The Rainbow Crystal has no known date of origin, but it was first discovered in its full capacity on Mt. Dybla the year 2901, but has been documented to have been seen as early as the 2100s as a non-stationary object. This was the world's first properly documented exposure to magic. The Rainbow Crystal is directly responsible for the Rainbow Curtain, and may also be the catalyst that allowed the Demons to reach the surface.
The Rainbow Crystal has 'wielders', or rather, people who are selected by the Crystal to use its power.
The more power the crystal uses, the more energy it drains from the environment around it, this is why areas around the Rainbow Crystal used to appear dried out and dead.
Some wielders of the crystal used it to affect the environment in specific ways, the effects weren't undone until another wielder chose to get rid of said effects; Said environmental effects usually took about a day to take place.
Mogo's Reign[edit source]
Mogo was the first wielder of the Crystal, she only used its power once and was not corrupted by it.
Vylova's Reign[edit source]
Amy's Reign[edit source]
Amy was the first crystal user to immortalize herself within the Crystal by sealing herself within it. Eventually, her body was absorbed into it.
Shoji's Reign[edit source]
Shoji was mostly unaware that she could use the Crystal's power.
She would often accidentally channel it when others attempted to usurp the power from her.
Ingrid's Reign[edit source]
Ashley's Reign[edit source]
Ashley, already being powerful, didn't need to employ the abilities the Crystal granted her often.
This spawned the existence of:
Samantha's Reign[edit source]
Samantha Spice used the Crystal's power often for strong magical attacks and to heal herself from the brink of death.
The area under the Rainbow Curtain suffered from constant quakes and paranormal events.
Cait's Reign[edit source]
Cait was granted the Crystal's power when she was sealed within it.
When she was sealed, the effects of the Rainbow Curtain ended, and life began teeming as it was once intended to.
Cait was freed of the Crystal's control and was able to freely use the power of the crystal without her mind being taken over.
Being sealed within the Crystal allowed Amy to partially posses her, causing a permanent personality shift to occur with her.
The Rainbow Crystal may have been made as a parody on the crystals that frequently appear in the Final Fantasy series of games.
The shape of the Rainbow Crystal resembles the Red Crystal from Cave Story, and functions somewhat like the Demon Crown from the same game, being a powerful item that changes ownership over time.
