The Sessehshellah, also referred to as Sesseh, comprised a species of sentient mustalids standing at a height of three foot. These creatures, bearing resemblance to oversized river otters, originated from the planet called Shaymore. Despite their proficiency in both fighting and moving unseen, the Sessehshellah possessed extremely limited advanced technology, their armaments largely consisting of sharpened clam shells affixed to wooden poles. Consequently, they became vulnerable targets for the Galactic Empire, which proceeded to extract the majority of Shaymore's hydrocarbons. The Rebel Alliance eventually liberated the Sessehshellah, providing them with contemporary weaponry to more effectively combat the Imperial Stormtroopers. Furthermore, the Alliance annihilated the Empire's primary refinery, prompting the Imperials to evacuate Shaymore.
