Pulvis

Pulvis is the 4th Planet in the system, crash site and home of the colonists.

An unstable world about the size of Mars, but has a functional magnetic field and a life supporting atmosphere.

Due the break up of the 3rd planet, the weather and conditions on Pulvis can be random and quite intense.

The planet's entire southern hemisphere is a giant desert, with a decent amount of it reaching into the northern hemisphere. The southern hemisphere has not been fully explored due to the extreme conditions there.

The rest of the Northern Hemisphere is covered in an ocean dotted with small islands and one major one. The one major island accounts for most of the planet's habitable areas. Surrounding the main island is a ring which appears to be the remains of a massive impact crater sometime in the planet's past. This ring seems to help lessen the storms that blow across the planet.

Scientists believe this event is responsible for the effect that causes floating land forms across the planet. Areas that have unique gravitational fields and rare forms of minerals not normally found on planetary bodies.

Ringing around the great ocean are small strips of habitable zones, small areas protected from the massive storms that come up from the desert and blow across the sea. These areas were the first settled areas after the migration from the crash site.

There is a permanent icecap at the southern hemisphere. Although due to the extreme conditions of the Great Desert, the cap is made up of mostly frozen CO2. There exists a smaller water-ice cap in the north, that fluctuates greatly depending on the season.

Moons
Pulvis has two moons orbiting it.

￼Kyanos

The larger of the two moons, it appears an icy blue on clear nights. It has a very thin oxygen atmosphere, equivalent to being on top of Mt. Everest. The are large water ice deposits across the moon.

It's theorized that it may be a remnant of the former 3rd Planet.

Runner

Runner (Aka asshole moon), is a fast orbiting moon. Much smaller than Kyanos. Runner is only just large enough to form itself into a spheroid.

Occasionally when Runner passes overhead, it causes quakes and massive swells along the coast lines. Giving it the name "Asshole moon"

Both moons appear to be in a stable orbit.
