He hosted a celebration for the birthday of local Imperial Moff Bandor , which was infiltrated by Rebel Alliance agents . Biology and appearance .

Their heads had two horn - like projections , which were sensitive to vibrations and air movements . History . The Mephitisians evolved on the planet Mephitis , located in the south - western portion of the Colonies . The atmosphere on their homeworld was noxious and offensive to all species that visited the planet . The Mephitisians were part of the galactic community from the time of the Galactic Civil War . The Mephitisian Mosh Pelkan was a Turf Boss on the planet Questal . Turf Bosses were criminal leaders who had agreements with the official District Commander s to keep down insurgency in exchange for the Commanders turning a blind eye to their activities . Originally traveling to the planet with the intention of becoming an ardanium prospector , Pelkan soon realized that importing illegal goods earned a greater profit . He established a significant power base and was a popular figure in Gralleenya , Questal ' s capital city . When Imperial Moff Bandor was given jurisdiction over Questal , he gave Pelkan control over a district of Gralleenya . Pelkan hosted a costume gala at his mansion to celebrate Bandor ' s birthday . The party was infiltrated by agents of the Alliance to Restore the Republic , who were searching for the missing agent Tiree . The Rebels believed Pelkan could provide them information on Tiree on the advice of local bar owner Tan Shilley , who had earlier suggested to Tiree that he contact Pelkan . At Pelkan ' s party , entertainment was offered in the form of gladiatorial combat . Despite their best efforts , the Rebel agents gained no useful information from Pelkan , but were instead forced to fight in the arena against his champion , Cromag . They defeated Cromag and escaped the party , eventually rescuing Tiree from where he was being held in Bandor ' s Palace . Behind the scenes .
