Ssi-Ruuk
The Ssi-Ruuk are a saurian race that invade from the Unknown Regions of the galaxy. This was around 4 ABY (After the Battle of Yavin), immediately following Return of the Jedi, in the novelization The Truce at Bakura. Native to the planet Lwhekk, Ssi-Ruuk are warm-blooded, reptilian beings covered with scales of various colors. Their blunt, oversized heads end with beaked mouths, and their bodies end with muscular tails. They have clawed hands and feet, and strongly-muscled hind legs. Their skin is so thick that it can withstand blaster shots with only minor burns to show for it. They are blind to The Force, and communicate with each other via a complex series of tweets and whistles. They also have scent tongues which they eject from their nostrils. Each hand has three opposable claws. They all have three eyelids. As a rule, the Ssi-ruuk were highly xenophobic, but were more disgusted by other species than afraid of them. Their religion greatly fears death on any planet that has not been "sanctified." As a result, they rely on a technology called entechment that involved capturing the life-energy of beings and using them as power sources. Entechment allows them to use unmanned spaceships for the majority of their combat.
