The emergency service droid designated "Millie" was assigned to Tem Chesko's freighter, a MILL-247-EE. This particular unit possessed a female personality matrix and was constructed to appear as a green-skinned humanoid woman, complete with blue optical sensors.
During a transport run from Cirus II to Tatooine carrying syntonium crystals, Chesko's ship was struck by an asteroid. This impact inflicted critical damage, disabling key systems including the hyperdrive and the comlink. The absence of a functioning hyperdrive extended the voyage from a mere two weeks to an estimated 71 years.
About eight years into the extended journey, the human discovered Millie within an emergency storage area and proceeded to activate her.
Throughout the extended duration of their isolation, Millie and Tem forged a strong bond, spending seven decades together aboard the ship. Their relationship deepened to the point where, despite Millie's artificial origins, they developed romantic feelings. On one occasion, Millie attempted to destroy herself out of the belief that Tem missed his former girlfriend, Maia, more than he loved her.
As Tem grew older and his health deteriorated, Millie became his caretaker. Ultimately, he gave her a laser knife and requested that she euthanize him. However, she chose to sacrifice her own existence, utilizing her internal components to create a cybernetic replacement for his failing heart.
