Chaaas' universe

The Chhhatyls are an humanoid race adorned with some plant attributes, like photosynthesis by their skin. The reaction gives them the glucose and a small part of oxygen (but not enough to survive underwater). Chhhatyls revere Chhoani, the Great Gardener who created the Universe, and his daughter Silene who gave the seeds of life. So gardening is a revered activity, and warriors make the best gardeners. They fear Koudriss, the god of chaos. Males wear their hair very long (see images on left), adorned with merit decorations or achievement insignia. The more braids, the more elevated their social prestige. Warriors sport the longest hair. The abondance and length of hair causes endless quarrels among male adolescents. Inversely, females wear their hair short, and their merit badges are pinned on their tunic. Biologically, they have a fragile abdomen (letting the light through to the foetus) that must be protected by a shell, so very few take part in physically-challenging sports. Kite flying is a popular female sport. Music and architecture are largely dominated by females. (Chaaas’sister Mirlenn is a well known compositor).    Their audition is keen, and the young can perceive very high frequency ultrasounds (vigils use special whistlers to calm down adolescents!) Like their tree-dwelling ancestors, Chhhatyls sleep in suspended baskets. Beds are only found in hospitals.

Other:

They fear and despise the humans, calling them primates or Zzoms (an insult since zzoms are local monkeys). The zzoms gave them the dreaded little-sun (a mutated dandelion) infestation...

Chhhatyls like playing a strategy game called gomshak. The matches can take a very long time, so many hot-tempered adolescents like Chaaas make a bad move and lose the match against older, and more patient, Chhhatyls.

Cities organisation: The cities are dominated by a high communication Tower, its base extending into the hospital and retired citizens' lodgings. There is a large park, a place of peace and quiet. Its center is occupied by a majestuous Bota, a very large tree revered by the Chhhatyls. At the other end of the Park, the Capitule (the city’s Hall) shelters the AI, called an Umbrella, its roots forming a net encompassing the city. There, the prefect and his magistrates directs the affairs of the city. The city tribune is a powerful investigator, while the street tribunes are day-to-day justices. The chief of vigils (police) is well respected.

The names: Males a named AAA kho YYY (father’s name) and females are BBB kha XXX (mother’s name) so the lineage can go back two ways. There are exceptions, of course. When a Chhhatyl marries, the particle Lar (father, mister) or Lor (mother, mistress) is added before the name (whether they actually conceive a child or not).  So the full name of Chaaas is Chaaas kho (son of) Chlaan.

The worlds:

Ch'lokan is the world Chaaas was raised by his parents, Lor Fulli and Lar Chlaan. It is, by Chh'tyl standards, a semi-desertic world. The luxurious vegetation is on a thin belt at the Equator. 

Talmur, Nasser et Chaaldar ("The first") are the three main cities on this world. The northern territories are uninhabitated, too cold. Ch'lokan has one small mooon, Paru.

Sioulann: is a fast-spinning planet, so the ocean bulges on the equator, leaving the poles emerged. As the axis in very inclined, the planet seems to “roll” on its orbite. Its year is so short that the dayear is 32 krels (a time unit, about 1.7 hours) long, two times the circadian optimum of Chhhatyls. (This leads to a spiral path of the sun in the north hemisphere sky). So the Sioulann settlers learned to fit a long siesta in the middle of the dayear. The Wind of Tammerlan timeline is expressed in dayears.
