A cluster of these ships came through from the void, with their flexible tendrils rippling in their trail. Small, with a smooth central hull, and long appendages acting both as sensors and sails for electromagnetic currents, the Spiritus were once partly organic, with a small symbiotic species inhabiting and navigating. None of the symbiotes seem to have survived the void, so the crew now consists of the quieter, more diminutive refugees, having sympathetically brought parts of the ship back to life. Seeing these ships together reminded the humans of video footage they saw of long-gone sea creatures, swimming and moving together as if with one mind.
