CARETAKERS

These sporocystine lifeforms originate from another galaxy. While visiting the Ocampan's homeworld, they didn't realize how destructive their atmospheric technology would be: it broke down crucial elements of the planet's ecostructure, forcing the Ocampa underground. Two "Caretakers" were left to look after the Ocampa, but one decided to leave to search for more interesting places. When the older Caretaker died, he left enough energy for the Ocampa to sustain for five years. During another encounter, Voyager discovered the Caretaker's mate, and learned that their species is known as the Nacene, and that they live in a subspace domain known as Exosia. The Caretaker was responsible for stranding Voyager in the Delta Quadrant, bringing them in a hope to procreate.
