Once upon a time, there was a world known as “Efer”. Which in the tongue of its inhabitants means "ash" or "nothingness".

The Eferlings were the dominant species of their planet, & they had evolved nearly god-like abilities.

But this evolution came at a cost. For the promotion of the technologies to reach these magnificent heights had eroded the very foundations of their biology to the point where the Eferlings had become functionally extinct...
still existing, but wholly infertile, poisoned by their own creations. 

For millennia, they told themselves their technology would save them in the end, but even as they watched their birth rates dwindle into nothingness, they were ensnared by the sterility of their disconnection from their bodily nature. All the while unaware that this was part of a plan: that this had happened before, that this would happen again.  

Living with the understanding that they were doomed to be the last generation of their species, the Eferlings had devoted their efforts to the creation of an egg-shaped vessel containing the mycelial network that is sustained with the decaying tissue from their own bodies.

Into this egg, technicians encoded the most deeply held thoughts of a whole population. Every single Eferling was given the opportunity to contribute an answer to this most profound question, "what is the one thing you would hold onto, if nothing else was left?" 

(Voices of the Eferlings)

“I hold onto my capacity to nurture and to choose life over death.”

“My spark of creativity and imagination.”

“Innovation, growth, playfulness.”

“I leave behind fertility and joy.”

“Passion!”

“Communion.”

“Reverence”

“Surrender”

These messages will be sent forth into the great cosmic ocean of space in an act of hope, of helplessness, of giving up control to the unknowable inhabitants of some world of pure thought that may... or may not actually exist.

In other words,they are sending out a prayer... for some semblance of salvation... as they await the fate of the washing away of their world.
