Yalaran

Yalarans were an extinct primitive race from the planet Yalara. Jedi Master Broden Kel Verdox installed a cloaking device on the planet to keep other planets from discovering the Yalarans until they were ready to integrate into the rest of the Galaxy. However this never happened - they were thought to have been wiped out by Noghri that Darth Vader sent to wipe out the population when he discovered their planet.
