Oswaft

The Oswaft are a species in the Star Wars universe, specifically mentioned in the novel "The Essential Guide to Alien Species". They are silicon-based lifeforms native to the atmosphere of the gas giant Bespin, a planet famously known for Cloud City which appears in "The Empire Strikes Back". Unlike other species, the Oswaft are adapted to live in the high-pressure and high-temperature conditions of Bespin's deeper atmospheric layers. They are essentially floating creatures that are able to manipulate electrostatic fields for movement and communication. They feed on the atmospheric plankton found in the planet's roiling gases.

The Oswaft's unique physiology allows them to endure the stormy conditions of their homeworld. Although the species has been referenced in the canon, there is little detailed description of their physical appearance. They are not often the focus of the primary Star Wars narratives, keeping mostly to their own environment below the floating platforms of Cloud City. Yet, their existence exhibits the rich diversity and creativity in the network of alien species that populate the Star Wars galaxy.
