She was a member of the Bajoran Resistance movement during the Occupation of Bajor. When Cardassian forces withdrew in 2369, Deela became a carer at the Tozhat Resettlement Center, looking after Cardassian war orphans that had been left behind.
In 2370, Doctor Julian Bashir and Elim Garak visited the orphanage to determine if Rugal, the son of Kotan Pa'Dar, ever resided there, however Deela was unable to account for him. This was later revealed to be part of a plot by Gul Dukat to embarrass Pa'Dar, who was his political adversary. (DS9: "Cardassians")
