On the planet called Buoyant, a species of four-legged creatures with elongated necks that were non-sentient existed prior to 54 BBY. In that year, Darth Plagueis, a Dark Lord of the Sith, and his apprentice, Darth Sidious, journeyed to Buoyant, where they participated in a hunt, chasing down a group of these quadrupeds and killing a number of them to amplify their link to the dark side of the Force.
