Crystal Dimension

The **Crystal Dimension**, formerly known as the **Rainbow Dimension**, is a partially destroyed prismatic region of the Universe that appears as sheets of shattered glass. It is home to very few, self sustaining planets and no stars and a constantly lit bluish-purple sky. The Crystal Dimension is home to the Crystal Citadel.

*The Crystal Dimension is based on the Crystal Dimension from Pendleton Ward's "Adventure Time" as well as Daron Nefcy's "Star vs. the Forces of Evil" and loosely based on the Crystal Dimension from the Minecraft Orespawn Mod.*

## Description

The Rainbow Dimension was a small magic filled realm comprised of bright prismatic colors and light. The planets were filled with life and color and the skies were home to large and beautiful rainbows. It was originally the heart of Yggdrasill and rested near the center of the Universe.

After Apophis' attack, the Darkness ripped apart the realm, leaving splinters of glass-like shards throughout fractured landscapes and a pink and purple crystalline sky, a realm now known as the Crystal Dimension.

## History

### Formation

#### The Heart of Yggdrasill

Soon after the birth of the Universe, and the formation of Muspelheim and Niflheim, a primordial entity emerged, the Axis-Mundi, Yggdrasill. With Yggdrasill came the colorful wormhole gateways known as Bifröst. The Bifröst emitted from and coalesced in the center of Yggdrasill, the heart of Yggdrasill. This realm was the first dimension hospitable to non primordial life.

#### Rainbow Goddess

The goddess and embodiment of rainbows, Iris, found the Rainbow Dimension and took residence there. She took control of the realm and was gifted dominion over the Bifröst by Yggdrasill's avatar, Fimbultyr.

#### Earliest Civilizations

The magical energy of the Rainbow Dimension seeded life to start forming. Two distinct races of magical entity evolved, a race of sapient bipedal dogs and multi-colored equine creatures known only as Rainicorns. The two species quickly populated and spread across the realm, eventually bumping into each others territories, sparking conflict between them.

### Rainicorn/Dog Wars

#### Battle for Territory

For millions of years, the Dogs and Rainicorns fought each other over territory in the Rainbow Dimension. Thousands of casualties on both sides and devastation across the realm.

#### Fall of the Rainbow Dimension

In the Earth year 48 BCE, the Rainbow Dimension was invaded by the current Dark One, the Ogdoad Serpopard Apophis. He made a home on a central planet of the realm and began to use the Darkness to shred the Rainbow Dimension into pieces. Iris quickly abandoned her home, fearing Apophis and the power of the Darkness. Apophis completely destroyed the planet he was on, leaving it broken apart. The Darkness tore the colorful Rainbow Dimension into shards of prismatic fractals. To stop the Darkness from spreading to the Nine Realms, Yggdrasill separated itself from the Rainbow Dimension, effectively removing its heart. Apophis eventually was found and stopped by the sun god, Ra, who chased him out of the destroyed Rainbow Dimension. Left behind was a cloud of dormant Darkness and the shambles of the realm.

#### Unification of the Realm

After Apophis' attack the Rainicorns and the Dogs were so angered and terrified by the Serpopard, that their conflict ceased. The two races joined over a common enemy: the Dark One. They took the destroyed remnants of the Rainbow Dimension, and created what was now known as the Crystal Dimension, where territory was meaningless.

### The Crystal Citadel

#### Planetary Remains

As well as reforming the Rainbow Dimension into the Crystal Dimension, the natives of the realm developed a countermeasure should the Dark One ever return. Taking the remnants of the planet Apophis destroyed, the Rainicorns and Dogs built a temporal stasis prison called the Citadel. The Crystal Citadel was specifically designed to contain the Dark One and the Darkness they manipulate. The leftover Darkness was purified into a glowing white substance that heals and regenerates instead of destroys. This substance was used as the blood of a group of cyborg wardens called Crystal Guardians.

### Continued Existence

#### Separate but Equal

Although united over their fear and hatred for the Dark One, not knowing of Apophis' defeat, the Rainicorns and Dogs still carried resentment for each other. Hate crimes between the two creatures continued for thousands of years.
