Brii is the innermost moon of Fern, and exceptionally dark, with most of its surface being covered in pitch black rock. However, this black coloration is broken up by a series of craters and large amount of ridge lines in the surface, revealing a layer of lighter rock below. The ridges are most likely formed due to tidal effects from Fern.

I had a lot of fun making this one. Ravines go brrrrrrrrr...

The second moon of Fern is mostly characterized by its large mass and strange purple colorations on its surface, indicating large deposits of exotic minerals.

```
This was around the time when I suddenly started experiencing heavy burnout while working on this system, that lasted until I completed Nimky and Kekko. As a result, this moon is rather generic looking. Maybe one day I’ll come back to it and the rest of the moons after it.

Prizzer is the first of two minor moons orbiting Fern. Its mostly covered in tholin deposits in a variety of concentrations. There are also decent deposits of copper salts in Prizzer’s crust, giving some patches on it a distinct green hue.

```
At this point, I had to start boosting the brightness of my screenshots. Very little light from Karat reaches here, and its a very dark place as a result. Also, nothing too impressive here either, but I at least love the colors I gave this one. There’s just a bit of emerald green in it too!

Lilly is a minor asteroid moon orbiting on the outer edge of the Fern moon system. It posesses an unusually eccentric and inclined orbit, and strange pink coloration.

```
I love asteroid moons, they’re so cute. Especially when they have fun colors like this one!
```

```
My N-Body simulation was actually NOT used here to generate the orbits. Which is bad, because I’m pretty sure I messed up the resonances of these orbits, and they desparately need to be fixed! Consider the orbital parameters listed here very WiP.
