Jellese

Jellese are the native sapient race of Tryslmaistan.

External
Jellese skin is damp from a protective mucus layer. This can be reformed into many objects, such as psuedopods that can be used for establishing mental contact, sharp surfaces, or fake facial features. Their only permanent organs are the two black patches that serve as their eyes.

Internal
The entire Jellese body is filled with plasm, a corrosive body fluid that can be shaped into organs. These organs are reabsorbed when their task is completed.

Jellese neuroplasticity rapidly declines at adolescence, which causes them to become pained and violent in unfamiliar events. The initial arrival of humans, and likely other races, to any worldplate has brought destruction and madness to its Jellese inhabitants.

Although they're not autotrophs, the Jellese rely on the ambient electanic field of Tryslmaistan for most of their energy. This force is analogous to electromagnetism.

Ancient History
Any alien species to occupy Tryslmaistan would eventually destroy the universe by destroying as little as one worldplate, which was all it takes to cause a kessler syndrome-like avalanche called "Stormfall". This means that there have been countless times where every species of Tryslmaistan had been accidentally or intentionally driven extinct, only to come back once the universe started putting itself back together. The Ktlikitkak were one such species to have entered and destroyed it. Chou believed that there was genetic continuity between Jellese from her cycle and that one, despite the nature of such an event. Multiversal rain carried humans to the worldplate of Myrmil, when the upheaval of life in an alien world with different physics had settled, humanity had retained its potential to thrive. The Jellese scientist Jovya Godan was resentful of this and developed Trauto-Yauronic "bombs" which would enable humanity's return to the universe 'Mundis'. Instead it created a new universe with aspects of Mundis and Tryslmaistan and caused the crumbling of Myrmil.

The Plan of Myrmil and its end
Whenever human refugees from their own stormfall landed on a worldplate, the mere knowledge of alien invaders would cause Jellese civilization to collapse. Only adolescents would have the capacity to remain sane from such a dramatic change while being still knowledgeable enough to rebuild it after the violence. Anything left would be destroyed when the stormfall arrives, as they were not part of the Plan Of Myrmil that humans used when evacuating a worldplate.

Eventually it was possible, through a uniquely derailed evacuation mission, for humanity to begin properly socially and technologically advancing. When humans started venturing out into new worldplates for reasons beyond evacuation, jellese and humans were able to exist as a single civilization with the technological edges of both, which developed into a civilization that was capable of lasting for long enough to see another alien race - the Burangidaeni.
