Primordial Evolution Game/Hastun

The tribe of Hastun:

The tribe of Hastun is a southern tentouz tribe that just arived at the edge of the jungle. But before trying to understant their story, it is rather important to know their biology.

Tentouz biology

An inside view of the complex metha-nervous system of the tentouz.

Behind the mouth, the food goes in a first stomach full of digestive acid produced by a liver/pancreas-like organ. The organic matter melts and the nutriments are directed to the lymphoïc system (it's not blood, it's a hemolymphoïc fluid thad does not carry oxygen). The chime of all the unwanted matter then goes to a second stomach full of a methanogen archaebacteria flora (like cows but way tougher). This stomach is equipped with a valve that opens to spread the gas into the baloon. At the bottom of the "balloon", all around the gas intake sprout, is a layer of neural cells. These cells are able to synthetize thousands of different neuro-transmitter. These organic molecules goes back and forth into the gas chamber where they then exist in two different form, normal and methylated (R and R-CH3) the methylation is a reduction of a CH4 molecule. This oxydation liberates H2 molecules that are known to burst in flames in contact with oxygen. that's why the baloon bursts in pierced. When the methyled form comes back to the brain cells, it is interpreted as an information.

The brain works by interpretating the variation of partial pressure of each neuro-transmitter. All around the chambers are disposed small neural glands linked to the lymphoïc system. This allows to "save" some neuro transmitter in liquid phase when their partial presure becomes high in the chamber. This is basically their memory. These glands are also able to deliver into the chamber foreign molecules that were taken in the stomach or synthetized by the organism or "saved" earlier. These can be coloured molecules, bioluminescent molecules, toxins, neurotransmitters, etc. This allows them to adapt their colour in order to communicate, confuse preys...

This system can also deliver into the back limbs to create the deadly bane-bubbles. The back sprouts only deliver H2 surplus that bursts in contact with oxygen and then propulses the creature. Their air holes acts directly as an interface to extract oxygen and have the sense of scent. The oxygen is carried in a secondary system of actual blood vessels. This system does not ever enter in contact with the gas chambers.

They have also a basical nervous system to control their limbs and the various valves scattered between the gas chambers and stomachs. The back tentacle are carved by an extention of their stomach richly vascularized with hemolymph vessels and covered by mucus producing cells. That allows them to create acidic poisonous and flamable bane mucus.

The neuro transmitter and their receptors on the brain cells are randomly synthetized by random gene splitting (that's the immunoglobuline synthetisis way) Then, like the antibodies, these receptor can randomly be sensible to some foreign molecule. This molecule can temporally become a new "thought component". In fact sentience of the tentouz depeds on their ability to absorb various foreign organic molecules in order to complexize their minds. A starving tentouz will become pale and get back to animal stage untill it can feed properly again to wake up its mind and have back access to its dormant memory. The aging of the tentouz is very slow, allowing them to last many years even in the dormance stage.

The tentouz have a very low mechanical power in their limbs. They can't lift great weigts nor strike with strenght. However, its four oposed tentacle digits are veru dextrous. The tentouz have the poorest audition. Their internal ear is alost entirely used for its balance keeping role.

Tentouz have a long lifespan (around 200 years if unharmed) and are unnafected by a lot of poisonous substances. They are hermaphroditic and reproduce by giving birth to a single larvae which have a long growth and need a lot of nutrients. The tentouz reproduce very slowly.

History of Hastun

Prologue: the first tale:

The word of the first tale, sigil of Hastun

The first tale of the Hastun: "The land that shall bear our lives, shall be ours untill the end of time"

The colour shades that may mean this has not been worn for a long time on the hides of the pale remnants of the hastun. But the words has not been forgotten, still inscribed deeply in the dormant memories since the beggining of the great starve. The prophet of these words may still be living in the pack, as pale and as the others, no longer differenciabe from its pairs. They have been guiding instinctively by this fix idea to seek for a more bounteous land. Wandering and roaming unnoticed on the desert sky for decades, they have forgotten the way to be themselves. But in a day, a green horizon appears, dawn to a new era. The hastun catches a prey, feeds on it and awakes. Then he knows that he must stay awakened for ever. A few hours past, and the entire tribe is back on its minds. Their hides turns blue again, and then moving shades start to scatter around in tidal colour waves. The skin on their foreheads pulses and a sketch starts to design itself. The words appear again: "The land that shall bear our lives, shall be ours untill the end of time" they become the sigil of the hastun. All wear it, but then an other word, made of darker shades is formed. The word of their forgotten past, their lost origins. This word becomes sense of obliviousness and sacrilege. Forgetting is forbidden.
