The Keltan were the dominant species of Orbis.
They resembled jellyfish in their appearance. Keltans were amphibious, and had very short lifespans. They iridesced when agitated — green was the colour of fear. They slept, danced and ate and regurgitated their dead to re-fertilise the seabed of Orbis.
The Keltan were made extinct when Orbis was destroyed by a stellar manipulator. (AUDIO: Orbis)
