Rejoice

Rejoice was a female Keskan who lived during the Last Great Time War.

She nursed the War Doctor to health when he arrived on Keska after detonating the Daleks' Time Destructor. For over one hundred days of care, Rejoice grew fond of the Doctor. She planned to join the Doctor on his travels in order to show him that he was a good person inside, but was forced to stay behind on Keska when the Time Lords came for the Doctor. (AUDIO: The Innocent)

She returned to her father upset over the Doctor's departure. After the Daleks invaded Keska, she stopped a Taalyen from killing the Doctor. She told him of the Dalek plans in the Thousand Worlds. (AUDIO: The Thousand Worlds)

In her later years, she became the leader of the Keskan Collective. In this role, she negotiated the surrender of her people. She tried to convince Seratrix about the futility of his plans as the Daleks will betray him like they did her father. She wanted to sacrifice her life to stop Veklin killing Seratrix. She was attacked and left for dead by Traanus, who seemingly killed her. When recounting the future history of Keska to the Doctor, Ollistra later noted that she wasn't sure if Rejoice had survived or not, but that she was remembered by her people as a symbol of peace and hope, and had statues of her likeness sculpted in her honour.
