Eldonians

The galaxy knows little about the Eldonian civilization, except that they ruled much of the galaxy until approximately 9000 years ago, when they mysteriously vanished, leaving only ruins.

GM-Level Lore Ten thousand years ago and further, the Eldonian Civilization ruled the galaxy. Their civilization was widespread, extending over a vast region of space. Their homeworld, Earth, was kept on the low-end when it came to massive projects and engineering, because they found it sacred. But the thing that was most key to their rise to power was the Possibility Engine, which produced the rare and powerful resource that people know as eldonium. The Possibility Engine has long since worn down, but the powerful resource it provided is strewn throughout the space the eldonians once inhabited.

When colonizing other worlds, the eldonians would genetically colonizers to allow them to better suit their environment, often incorporating the biology of native species. About nine-thousand years ago, however, the Eldonians shut down all of their technology and hid away the knowledge of their history to hide from AEON.

Those who look for their homeworl don’t tend to suspect Earth, as the Possibility Engine was purposefully kept extremely hidden. To any outside observer aware of available Eldonian history... Earth is simply a backwater world that happens to have a bit more eldonium than most.

Since they vanished, the remaining eldonians - having lost their history - eventually began to rebuild their society. This gave rise to many humanoid species across the galaxy, such as the Kyan and the Auronians.
