During her time as head of the Guildhouse, MacMillian amassed a large amount of navigational information regarding the Kathol sector and was willing to copy it for members of the Corellian Merchants' Guild for a fee of 100 credits. In 8 ABY, the New RepublicCR90 corvetteFarStar stopped over at Gandle Ott while on a mission to track down the rogue ImperialMoffKentor Sarne. The crew of the FarStar was in need of navigational charts of the sector, as Moff Sarne had wiped the records on the sector capital of Kal'Shebbol clean during his withdrawal, and the crew only had access to partial maps that did not show details beyond Gandle Ott. During their layover, MacMillian was one of the potential sources from which they considered obtaining the information.[1]
By 8 ABY, MacMillian was an aged woman, with salty hair and wrinkles covering her face. She possessed a no-nonsense attitude, and the Corellian Bloodstripe that she had earned proved her tenacity, displaying the fact that she was not a woman to cross. She acted friendly toward fellow Corellians, especially those allied with the New Republic, as she believed that the galactic government was capable of restoring peace to the galaxy.[1]
MacMillian's character does not have to be encountered in the adventure; the main aim of the players is to acquire navigational data and the adventure provides several ways for the players to obtain it. MacMillian is only one of several options, and her participation in the scenario is dependent on the player's actions.
