Star Wars (1977) #86 and Star Wars: Jedi Council - Acts of War #1

The Expanded Universe is rich with planets and species for writers to use.  Longtime readers were rewarded when a planet or species from an older story was referenced in a newer story.  Dark Horse incorporated elements of Marvel's original series in their stories.  This was the case with the Yinchori from the planet Yinchor who were introduced in Marvel's Star Wars #86 and were use again by Dark Horse in Star Wars: Jedi Council - Acts of War #1 over 15 years later.

Star Wars #86 starts with Leia on a mission to Yinchor aboard a Yinchori shuttle.  As they near the planet, she learns from the crew that she is being traded to the Empire in exchange for the captured Yinchori Elder Council.  Needless to say, the Imperials do not hold up their end of the bargain and shoot down the shuttle over the planet and Leia is the only survivor, setting up the main story of her confrontation with an Alderaanian Imperial Stormtrooper.

Star Wars #86a - Marvel Comics, U.S. (August 1984)

In Star Wars: Jedi Council - Acts of War #1, the spelling of Yinchor is changed to Yinchorr, but there is no mistaking the species.  Yinchorri are green skinned reptilians with a turtle-like head and bulky bodies.  The story in the 4-part mini-series takes place prior to the events of The Phantom Menace.  Darth Sidious manipulates the Yinchorri, recently brought into the Republic, into attacking nearby planets and the Jedi become involved in the Yinchorri Uprising.  According to Yoda "... after so many years of relative peace, troubles me does a threat like this".  Sidious himself tells Darth Maul that "Either the very stubborn and warlike Yinchorri-- whose inconvenient resistance to mind control could present a problem in the future-- will be brought low, or... Jedi will die."  Much of this implies this is Sidious' first overt move into manipulating galactic events into the Sith's favor.

Prior to their appearance in Jedi Council - Acts of War, the planet Yinchorr was used in Crimson Empire #1 as the location of the training facility for the Emperor's Royal Guard.
