Kuli

Kuli was a human child who lived in the 26th century with her mother Jenifa on the planet Auros. When the citizens of Auros used Osterhagen nukes during the Second Dalek War to destroy their planet in order to escape from a Dalek fleet, their evacuation fleets were captured by the Daleks in a trap ordered by Dalek X. All the evacuees were taken prisoner to work as slaves in the Dalek mines of Arkheon to breach the Arkheon Threshold.

Kuli and her mother aided Koral and Cuttin' Edge while working in the mines. The Tenth Doctor tried to free them, however, pretending to offer Dalek X his TARDIS but claiming he needed six people to operate it. Dalek X refused to let Kuli and Jenifa go, saying four others would have to suffice. The two were sent back to the mines.

Following the defeat of Dalek X, Earth Command was able to send an attack force to Arkheon. They defeated the Daleks and freed all the prisoners. (NSA: Prisoner of the Daleks)
