Malgan Market existed in the city of Iziz, which itself was situated on the Inner Rim jungle planet of Onderon. This market acted as a focal point within the city, where merchants and traders conducted sales of various items, notably diverse types of fruit. Many stalls used colorful canvases, supported by poles, to create shaded areas for both the goods and the vendors.
During the time of the Onderonian Civil War, the Confederacy of Independent Systems seized control of Iziz, which included Malgan Market. As the Onderon rebels started their campaign to reclaim the city, Lux Bonteri, a rebel, and Ahsoka Tano, a Jedi Padawan, successfully eliminated multiple battle droids within the market's confines. Soon after the rebels staged a public display, Dono, a human rebel, informed Steela Gerrera, their leader, that she had learned King Ramsis Dendup was scheduled for execution the next day.
The initial appearance of Malgan Market was in "Front Runners," which is the third episode within the fifth season of Star Wars: The Clone Wars. This particular episode was initially broadcast on October 13, 2012. The market's name was first established within the episode guide on StarWars.com, which was made available on the same day.
