A pilot since her childhood, Attan studied Sullustan geology from SoroSuub Extension programs. After graduating, she joined the Galactic Outdoor Survival School, and was a member of the prestigious Twilight Class. Attan led one of the most dangerous parts of the final trek that led to the impressive graduation of the Twilights around 10 BBY.
After that, Attan joined the Rebel Alliance alongside most of the other Twilights. She became a pilot instructor for the Alliance Navy. Then around 2 ABY, Attan was assigned to the Roche Asteroid Field, where she helped in some minor modifications to the prototype B-wing starfighter.
