Lithos

Lithos is an exoplanet approximately 2.55 million light years away in the . It is the third planet from its star, Porios. Lithos is home to the Lithon species, an intelligent race that has become specialized towards space travel and interplanetary colonization.
==the Lithon species==
The Lithon are an intelligent species that inhabit the planet Lithos, which resides in the Andromeda Galaxy. Though extensive accounts of the species, its origins, and its anatomy have been given by The Two, little else is known.
Lithos operates under a very old, very strict caste society led by an oligarchy. The queen, Modêsh, is incredibly old and predates any other Lithon. Beneath her are her oldest and most powerful assistants, the Theon or Theongorai. Together, they are treated as gods and dictate society to a hair's breadth.
Modern Lithoi are synthetic, constructed in laboratories and created to strict specifications. However, their anatomy is based on an older species that was largely biological.
==Physical Characteristics==
Lithos is a rocky planet covered largely by water-ice and liquid ammonia. Its most striking features are its bright red color, its rings, and a huge W-shaped feature in the northern hemisphere.
Liquid Ammonia covers 27% of its surface, with a deep red atmosphere and pink clouds. The atmosphere is made mostly of methane and carbon dioxide, making it an inhospitable place for humans. Its average surface temperature is -65 °C. 
The processes behind Lithos's extremely red features are poorly understood, but it's thought to originate in the planet's ammonia cycle. 
The W-shaped feature in the north of Lithos is actually 3 distinct bays: [my excel decided not to work as I was writing this] 
The rings of Lithos are relatively young. 20 thousand years ago, a large asteroid about the size of Vesta was captured by the gravity of Lithos. This asteroid is known today as Bombos (from Ancient Lithon bɑnəβ "wander"). The asteroid passed too close and too slowly to keep itself together, and it collapsed, spreading out around Lithos and forming its rings. 
The rings orbit 3.27 to 3.5 radii from the planet, are about 20 km thick and composed mostly of iron and rock. 
Lithos has 2 major moons: Gaproros and Thelakos. It also has two captured moons: Helokon and Grimossis.
