Sheckil's twin

The Human male Sheckil, an Imperial lieutenant during the Galactic Civil War and a native of the planet Concord Dawn, had a twin brother who became a famous mercenary.

Behind the scenes
Sheckil's twin brother was first referenced on the "Lieutenant Sheckil" card from the November 1997 Cloud City Limited expansion set of the Star Wars Customizable Card Game. The card's mention of a twin mercenary brother, as well as the fact that Sheckil is from Concord Dawn, was intended as a tongue-in-cheek reference to the fact that actor Jeremy Bulloch played both Sheckil and the bounty hunter Boba Fett in the film Star Wars Episode V: The Empire Strikes Back. At the time of the card set's release, Boba Fett was canonically established to have been from Concord Dawn as well, according to the 1996 short story The Last One Standing: The Tale of Boba Fett. However, any such connection between the two characters was trumped by the release of the 2002 film Star Wars Episode II: Attack of the Clones, which established Fett as a clone "born" on the planet Kamino.
