Tiafe is a hydrocarbonia planet harboring organic and exotic life, both of which were unicellular at the moment of their discovery and multicellular today. The planet is located in the system Tiaun at 2395.60 ly from Aegyn. Tiafe is the homeworld of maruses and capital world of United Nations of Tiafe.

This planet has 2 major moons, 7 dwarf moons, and a ring above 1,904.1 kilometres of the surface.


Tiafe has a mass of 4.27599 terrestrial mass, a diameter of 21,331.8 kilometres and a surface gravity of 1.5369 G. Hers axial tidal is of 61°37'32.08". The planet has a average temperature of -183 °C and a atmosphere of a pressure of 0.0541 ATM and a density of 0.087165 kg/m3 composed of:

  • Methane (CH4): 84.7777 %
  • Dihydrogen (H2): 14.5429 %
  • Dinitrogen (N2): 0.630633 %
  • Argon (Ar): 0.0259417 %
  • Carbon monoxide (CO): 0.0148822 %
  • Ethylene (C2H4): 0.00347475 %
  • Neon (Ne): 0.00280253 %
  • Helium (He): 0.00115046 %
  • Krypton (Kr): 0.000404718 %
  • Ethane (C2H6): 6.66724e-005 %
  • Acetylene (C2H2): 2.4603e-005 %

The planet is covered by 30 % of clouds, with a average wind speeds of 98 km/h and has average rainfall of 250 centimetres.

Tiafe was discoved by the humeiga in 2,187 CE[1] and it was interesting because of the presence of a large amount of methane, like Aitta.

An expedition was launched in 2,722 CE to gather more information about this planet and see if it can be settled on, to collect methane and other resources.

The surprise was the discovery of the two life forms on the planet : exotic unicellular life on the surface and subsurface, and organic unicellular life in the subsurface ocean. Since, the settlement of this planet is prohibited to avoid contamination of the species native to the planet.

In 2,724 CE, many temporary research outposts were built on the planet to study the evolution and the coexistence of two different kind of life forms, however the outposts were deconstructed in the year 2728 CE. In 2,728 CE, a law was created that prohibited the settlement of Tiafe to preserve its life.

But in 2,792 CE, a orbital outpost was built around the planet to study the life.


The planet is mostly covered with plains, forests and badlands, as well as seas and oceans (62.23 %), where Ocutha is the largest ocean. The planet has 8 continents:

  • Ganyor
  • Iem
  • Midom
  • Marf
  • Cort
  • Wenres
  • Omeit
  • Tep

The highest point is Oviem on the continent of Iemat at 7,866 meters above sea level.


As mentioned above, life at the time of it's discovery (2,722 CE), were exotic unicellular life on the surface and subsurface, and organic unicellular life in the subsurface ocean, coexisting together.

In 2,798 CE, scientists saw the first exotic multicellular flora to appear on the surface of the planet. It was a surprise, because for scientists, this were expected to happen a few million years later. The flora looked like dark purple, similar to their purple unicellular ancestor, but darker.

In 6,372 CE, it was the exotic multicellular fauna's turn to appear on the ocean of the planet. It was astonishing. Scientists don't know the reason of the fast evolution of this life form either. In 89376 CE, with the collaboration of a UNT research team, the question is solved by analysis on a crashed spacecraft at Laker demonstrated that it belonged to the Sedrua civilization, dating back over 1 million years, it seemed to act on the life of the planet as well.

In 14,548 CE, the first organic fish is detected by the scientists from orbit. The theory being that maybe multicellular life existed earlyer, under the subsurface ocean, and was not detected.

In 21,731 CE, the exotic multicellular fauna appeared. It looked like a toad.

Civilization : Maruse

For more informations, see Maruse.

Scientists thought that life seems to have reached its stage, before making an even more surprising discovery in 42,694 CE, a dark purple mouse like civilization started across the planet. It was discovered by chance by a trainee in a formation of exobiologist. First, other scientists thought it was a joke, yet it was a true discovery.

The names given by humeigas to this civilization is Maruse.

The discovery of the fire for this civilization took more time than human civilization - because of low oxygen concentration in the nature - in 42,824 CE.

In 89,362 CE, the first satellite was launched into orbit... Scientists think they were discovered, because after some years after, in 89,375 CE, they received a message from this civilization... in the Lapeito language. The message was of course transmitted to the Noyminod del Auyen headquarters, before transfer to Regnum Aureiga. In the meantime, scientists introduced themselves and said that they sent the message to their leader (UFSS).

So since that day, United Nations of Tiafe (UNT) are under the protectorate of the Regnum Aureiga and exchange the knowledge.

A project to a dome city on the planet for humeigas is planned with the accord of the UNT.
