Ackarra

Ackarra is the fifth planet of the Szon system. It is located on the outer edge of Szon's life zone and just barely supports life. The planet is also known for being the first extraplanetary Dhragolon Federal Monarchy colony.

Atmosphere
Ackarra is a young planet. Life had only clambered to the surface 20 million years ago, though it is primarily restricted to lichens and algae. Because of this, Ackarra has excess nitrogen in its atmosphere which has yet to be utilized by the planet's flora. Although still breathable by Dhragolon, the atmosphere will cause nitrogen intoxication to species from oxygen-rich environments. However, the atmosphere is just barely breathable, and even to Dhragolon, the air is thin with little oxygen. During the day, the sky is a light purple color caused by the large amounts of ionized nitrogen.

Weather on Ackarra is highly volatile yet unpredictable. The planet's thin atmosphere gives it a very wide temperature range. During noon when temperatures peak at their highest, some of the ice around the equator begins to melt, and that water later evaporates after being exposed to the sun. Thunder clouds begin forming but during and after sunset, wintry mix and hail come down instead of rain. Ackarra's hailstorms are powerful enough to damage structures, and many safety precautions had to be undertaken.

Geography
Ackarra is covered in less than 5% surface water. The poles have two enormous ice caps that cover most of the planet except for an equatorial, unexposed band of gray rock with several patches of lichen surrounding the few bodies of water on the surface.

Surprising for this planet, Ackarra is actively volcanic and has shifting continental plates. Tidal pulls from Ackarra's giant, silver moon, Klathos, cause geysers to spew out that almost immediately refreeze, leaving a landscape of crystal spires. Large glaciers have carved out large lakes, that after getting heated by the planet's geothermal heat have allowed stabe liquid water on the surface to exist.

As Ackarra is the closest habitable planet to Szon's asteroid belt, impact craters are more than common. Such asteroids delivered organic molecules and water ice onto the planet, and eventually creating the planet's underground oceans. Some of the lakes on the surface connect to these vast oceans allowing for some of the planet's hidden sea creatures to be explored.

Biosphere
Ackarra has evolved a primitive, yet vibrant ecosystem within its lakes and oceans. The creatures here consist of arthropod and mollusc analogues, most of which are bioluminiscent. The ecosystem predominantely survives near large geothermal vents, but with the advancement of lichens to the surface, photosynthetic algae has evolved. Entire ecosystems of both microbes and macroscopic zooplankton flourishes towards the surface of Ackarra's lakes.

Colonization
Settlements on Ackarra are around the equator built around the planet's lakes. Building a self-sufficient colony was relatively easy. As a result, Ackarra's population exploded and is currently the most populated non-capital planet owned by the Dhragolon Federal Monarchy with a population of just over one billion.

Agriculture was fairly easy due to the nitrogen, rich atmosphere and already nutrient-filled soil. However, farming is done within greenhouses as the Dhragolon's edible plants and cash crops cannot withstand Ackarra's chilling temperatures.

Moon
Klathos is a moon coated with layers of palladium and platinum. It is roughly one fourth the size of Ackarra, and some consider it to be a double planet. The moon is mined for its minerals.
