Crystal System Colony 215 is a location in the mobile game Unleash the Light. It is a small moon that functioned as a mining colony formerly belonging to Yellow Diamond.
Description[]

Outpost K-3.
Crystal System Colony 215 formerly served as a remote mining colony under the control of Yellow Diamond. The colony, and the Peridots who inhabited it, were managed by the Garnet Demantoid. On this colony, Peridots with yellow limb enhancers were stationed here and would work on digital screens located outside of circular outposts. After Steven sent out a broadcast that ushered in Era 3, Demantoid had all broadcasts sent from Homeworld blacklisted. And so, even after the start of Era 3, the Peridots were made to continue their duties. However, the Peridots were said to have diligently studied the broadcast every solar-cycle.
Sometime during the beginning of Era 3, Demantoid incorporated Light Constructs using her Prism. Some of these constructs piloted floating red drills, which can be seen scattered all throughout the area.
Terrain[]
The colony is mostly grey, with many craters creating large grey walls that Steven and the Gems navigate through. In the distance, large spike-like geological formations can be seen sticking out of the ground at an angle.
Crystal System Colony 215 contains several cave systems, in which the surrounding mineral appears to be pink.
Ecology[]
Despite being a moon, Crystal System Colony 215 supports life on its surface. Although there are no known fauna to have been seen existing on the planet, many various forms of flora presented themselves as background elements.
- Triangular pink bushes: Many triangular pink bushes of various sizes could be seen scattered throughout the surface.
- Grayish-pink shrubs and weeds: Shrubs and/or weeds of a greyish-pink complexion could be seen with leaf-counts ranging from 2 to 4.
- Blue flowers: An uncommon type of plant witnessed on Crystal System Colony 215 were small blue flower-like plants that were typically located in groups of 2 to 3.
- Large pink leaves: Located exclusively inside of caves were large plants with pink leaves.
Infrastructure[]

The abandoned Kindergarten.
Crystal System Colony 215 has some infastructure reminiscent of the Palace of Light and Blue Diamond Colony 4. The most prominent features include the aforementioned circular outposts as well as the hot pink walls shaped like squiggly-lines. Some other elements include velvet-pink stairs and complex dark-pink spires that were located in some areas.
On an abandoned side of the colony is a Kindergarten. This location is surrounded by mists, gray colors, abandoned Injectors, and exit holes. In this location, the Drill Boss appears out of a wall to fight the Gems.
