The Star World

The Star World was created when two Celestial Bodies collided, one with a light energy, and one with dark energy. These became the Cosmic Star and Dark Constellation. The Cosmic Star is what gave way to the Star World, forming reflected versions of the source worlds of characters and of the characters themselves from both SleepySluttyRosalina69 and PsychoSilver, as well as some select other universes.

The reflected worlds are amplified in certain ways, or changed entirely. They are still familiar settings, but are also very different.

Reflected worlds can be accessed through Cosmic Portals, special portals made by Guardians using magic. The Star World itself can be accessed from source worlds by entering the Cosmic Star, which acts as a portal to the Starmaker Crater. The Cosmic Star also acts as a power enhancer, turning basic characters into heroic figures called Guardians.

## Known Locations

### Starmaker Crater

The main location of the Cosmic Star, which Rosalina usually guards.

### Sammy’s Church

The main home of Sammy, Ruvina, Selena, and Razz, reflected from the main setting of Mid-Fuck Masses. The demonic aspects were amplified by Cosmic Magic, with pentagrams on several places in the church.

### Koopahime Mansion

The main home of Taylor Koopahime. A magical mansion surrounded by a dense forest. The magical energies were amplified by Cosmic Magic, making the location look like it was right out of a fairytale.

### Rainbow Factory

The main lair of Pinkamena. The horrifying aspects of the factory have been amplified by Dark Cosmic Magic, making it into a hellish realm where nobody ever escapes. During Chapter 1, it acts as the base of operations for Pinkamena to control the Broken, although she would later have to team up with the Guardians after Bowsette betrayed her.

### Bowsette’s Castle

The main lair of Bowsette, during Chapter 2. Dark Cosmic Magic amplified the evil aspects of the castle, turning it horrific and twisted, as a perfect lair for Bowsette to lead the Broken, on a quest for more power. Bowsette would soon have to team up with the Guardians, after losing the Dark Constellation to Hel.

### Hel’s Mountain

The main lair of Hel during Chapter 3 and Chapter 4. Not from Hel’s source universe, but based on a misconception of Hel where it looked like she lived at a mountain due to using Freakachu as a basis. Hel’s Mountain is made by Dark Cosmic Magic, residing within the Star World exclusively. Hel would have to team up with the Guardians, after losing the Dark Constellation to Jane Everlasting.

### Jane Everlasting’s House

The main lair of Jane Everlasting during Chapter 5 and Chapter 6. The Dark Cosmic Magic corrupted it into a completely new location, taking the form of a large casino she rules over, using the Broken to invade other locations and expand her corrupted reign. It is the current endpoint in-story, though Chapter 6 ends with the casino form reverting to a more accurate depiction of Jane Everlasting’s House. It is unclear why this occured, though it’s likely because Jane Everlasting’s House relied on the Dark Constellation to keep it’s status as a large casino, whereas previous villain lairs used a more natural source of Dark Cosmic Magic.

### Rosalina Tennis world

Little is known about the reflected version of the Rosalina Tennis universe in the Star World. It is implied, however, that it is still very much a giant tennis court in space.

### Ari’s Garden

A large garden location in the Star World. The main lair of Ari the Sceptile during Chapter 7, where she enacts plans she thinks are helping, not realizing she’s hurting the Star World. In-universe, it is described as being an amplified version of Ari’s House from Dark Cosmic Magic using Ari’s chlorokinesis and love for plants. There are a few gates in the garden only characters from either the PsychoSilver or The Banana Cosmo System universes can get through.
