Ekabiun is one of the oldest sentient species which has emerged after the star that they call "sun" formed only 1.5 billion years. They like a cold environment at about -194°C. When the space exploration era arrived, they start to explore the space but discovered nothing except blue supergiant placed all over the galaxy. They found a very tiny amount of planets equal to fewer resources. That amount of resources worth nothing for travel to nearby systems.
They can travel to other galaxies. But all are the same as their home galaxy, which makes them stuck at a type 3.99 civilization. That level of technology, they can build new rocky planets from hydrogen and helium which is common, by fusion them into heavier elements such as carbon oxygen , silicon , iron , gold ...
A billion years later. The great war happens due to the war. It makes Ekabium civilization collapsed. But they leave the technology for the future civilization to develop them.
Ekabiun anatomy information is not complete, about 98.3% is lost. We only know how their inside organ work , how their skin looks like ETC. What we know is, they have 3 eyes that mostly catch infrared light. They have very thick fur used as the insulator. They have nervous system that ganglion scattered across their body, each ganglion work like a computer core, that mean their body is the brain.
In the blue supergiant rich environment with a minuscule amount of metal. It forces them to build the planets because planets are not available for colonization. But to extract metal from interstellar space is the tremendously expensive process, the easier way is star mass, it easier to split star into the smaller ones. Ekabium civilization has a cheap nuclear fusion reactor, many of them are equally faster many times to convert hydrogen and helium into planet-building material. This is the most famous technology that Ekabiun leaved for us.
About less famous ones. They are travel method , sensor , planet destroying weapon , Dyson sphere , climate controller and livestock management.
Unlike fossils, they can be decayed over time. But technology isn't organic thing, it is the knowledge that can be encoded, it can live longer like a stone. It had recovered 99.999994% of all that Ekabiun was created.
