A shelled creature species inhabited the planet Kyrouac, which was located in the Inner Rim.
The shelled creature's debut occurred in Alone Against the Empire. This was a solo roleplaying game created by Lester W. Smith to be played with Star Wars: The Roleplaying Game from West End Games. It was featured in Challenge 32 during 1988. Because its release bypassed the Lucas Licensing procedures, its place in the Star Wars Legends canonicity was never officially established.
