Zephronites

Zephronites are amorphous beings, and have cytoplasm composed of a combination of dinitrogen tetrahydride and water. Their cytoplasm contains the organelles, and the CGP (central genetic package) which distributes fresh genetic information. Lacing through the cytoplasm is the neural network, like in a jellyfish or octopus, as well as the cytoskeletal transport tubes. Their cell membrane is composed of a rubbery net, allowing them to travel through the vacuum of space for prolonged periods. Their neural net is connected to the Mind Center, a massive sentient bulb that controls all Zephronites in the universe from the center of the planet.

Zephronites in rollplay are bits of old man's beard lichen, and the Mind Center is a tree gall
