Arco

Arco was a planet on the edge of the Milky Way in Freespace and relatively unexplored and unknown.

#### **System**

A Uniary Starsystem, the star Zethk Prime is a small white dwarf.

#### **Moons**

None, Arco was moonless and it's sea had hardly any tidal forces.

#### **Surface**

From orbit the world appears as a green and grey-white sphere,
under these thick, poisonous clouds large areas of the surface are covered in
seas of perchloric acid and is dotted with small islands of mostly black onyx
and macrocarbon, this rock has strong resistances to high levels of acid but
still undergo the same processes of erosion as most rocks against liquids. It
is also geologically active with underwater (or underacid) quakes prominent,
but with most of the planet liquid, little evidence of this is noted on the
surface.

The planet
is quite dark because of its distance from its small sun, with light particles
scattered through the clouds, but the seas themselves do generate warmth when
interacting with rock and the proposed theory of life existing on the world
relies on deep-acid colonies of microbes existing at warmer seabed levels, but
no studies have been made.

#### **Atmosphere**

Mostly sulphur dioxide and nitrogen released with acidic erosion.
The planet often undergoes frequent acid rain thunderstorms and has a
particularly strong ionosphere and a large magnetic field for its size making
flight through the atmosphere difficult even for advanced starships with
electronic instruments and sensors rendered pretty much useless by the
electromagnetic interference from these storms.

#### **Climate**

Dangerous, caustic, dark, Arco’s climate is inhospitable for nearly
all known life, and as such the planet is not thought to harbour life, although
possible microorganisms are suggested to live deep in the oceans of superacid
where chemical reactions between the acid and the rocks create warmth, but
theories are most unlikely.

**Planet**
Class**:** **U**

**Diameter:**
3920.2 km at equator.

**Population:** None officially.

#### **History:**

Discovered by Human explorers in 2620 as planet Ex5547-A on
Galactic Cartography charts, the planet was of little significance for any
tactical or industrial purposes for the early Earth Global Alliance. However it
was also discovered and named by the Ezaki 700 years earlier and used as a
vennimite mine, but wielded little results and with very difficult mining
operation the mines were quickly closed and they are now all but eroded, but
samples of the acid have been taken for study as both an industrial tool and a
weapon. Arco which means "Decay", although it is sometimes spelt Arko
or Arzo depending on which Ezaki language is used as an English reference, it's pronunciation remains the same, with emphasis on the 'C/K' sound.

The planet
was suspected to hide a large terrorist base of a major Ezaki Kon extremist
group named the Servants of Kona, led by the infamous Nez, who in his time came to
be known as "Nez Ka Zazuri Kazad or "Nez, the Slaughterer of
Kazad" (Nez's home city where he and his father bombed several districts
when he was young).

If any
bases do exist on Arco they would have to be well hidden and well protected
from the acid rain and powerful electrical storms which constantly plague the
world.
