Nurls Yorksin was a Twi'lek of the female persuasion, residing on the planet Coruscant. She operated as a clandestine agent for the Republic Strategic Information Service throughout the period known as the Cold War. Yorksin's assignment involved preventing the illegal import of goods into Coruscant.
During the Cold War era, a time of tension between the Galactic Republic and the newly reformed Sith Empire, Nurls Yorksin, a female Twi'lek, made her home on Coruscant. While residing there, she functioned as a secret agent for the Republic Strategic Information Service, collecting information within the Senate Plaza area.
Upon learning that Black Sun criminals were seizing the shipments of legitimate traders, Yorksin sought assistance from an unaffiliated operative, aiming to protect the identities of her fellow operatives. As the independent operative discovered Black Sun loader droids and retrieved their stored data, the Strategic Info Service agents managed to pinpoint the whereabouts of the pilfered goods and gain access to Black Sun's storage facilities.
