Simply an organism made up of a multitude of smaller organisms, which in turn are made up of smaller organisms, and so on and so forth. Midden encountered an immense mass of organic matter drifting through space while on a deep charting run, and rapidly discovered that the very large blob of life was indeed a sentient superbeing, made up of countless conciousnesses, which had organized themselves to be capable of space travel and planetary observation.
Midden's scientists were able to discover that with three single celled organisms combined into one larger one, a sentience was born, and was found to be fully capable of free thought, and decision making. They could combine into masses, either to perform a function or to channel energy, into an engine or weapon perhaps. Using the most rudementary of chemical reactions, these cells we able to obtain massive amounts of enegry from raw organic matter, even plastics and synthetics like rubber and oil.
Midden has only encountered one such amalgamated organism, but one sentience hinted at a planet-scalled being of gargantuan intelligence and wisdom of the universe. An expedition has been prepared to find said being.
Yeah...this picture took some time. It's quite possibly the most lead I've ever put down on a 9x12 sheet.
