Ohila

Ohila was the High Priestess of the Sisterhood of Karn and was active during the Last Great Time War and in its aftermath.
== Biography ==
Ohila knew the Doctor, with an implication of her knowing him as far back as his first incarnation's childhood. (TV: Hell Bent)
=== The Last Great Time War ===
Ohila was pleased to see the Eighth Doctor return to Karn, but pitied the fact he had been killed in a crash landing. The Sisterhood revived him for four minutes, and Ohila begged him to help them by taking the Elixir of Life. After arguing with him, she convinced the Doctor that he was the only one capable of stopping the war, and he could not help anyone by running away from it just to uphold his principles as the Doctor.
Once the Sisterhood retrieved Cass Fermazzi's body from the wreckage, the Doctor gave up hope and decided to enter the Time War. He drank the elixir which Ohila had taken the liberty of preparing, and he regenerated into a warrior for battle. (TV: The Night of the Doctor) Ohila later told the recovering Doctor that they were burying Cass, but he refused to attend. Ohila contacted Commodore Tamasan about the Doctor’s recovery, but their conversation quickly became heated.
=== After The Time War ===
Ohila met the Doctor again in his twelfth incarnation. He was present on Karn when Colony Sarff arrived and spoke to Ohila about searching for him on behalf of Davros. Sarff gave a message to Ohila to pass on to the Doctor (unaware he was listening), stating that "Davros remembers", and an invitation to meet him one last time. (TV: The Magician's Apprentice) She didn't believe his answers when discussing the invitation, stating that it was easier to assume he was lying to her rather than trust his word. She also indicated that she considered herself and the Doctor to be friends, an assertion he didn't refute. Before leaving Karn, the Doctor gave her his confession dial, saying that she'd know who to give it to. (WC: Prologue) She later gave it to Missy. (TV: The Magician's Apprentice)
When Ohila heard the Twelfth Doctor had returned to Gallifrey, she went there and met with the Eleventh General and the High Council, much to the Rassilon's irritation. Ohila watched Rassilon's efforts to reach out to the Doctor with amusement and told Rassilon that the Doctor didn't blame Gallifrey for the horrors of the Time War, but rather Rassilon himself. After Rassilon was overthrown, Ohila spoke with the Doctor about his actions and about the Hybrid. She later consulted with the General about the Doctor's actions and, deep in the Cloisters, told Clara what happened in the Doctor's confession dial and why. As the Doctor and Clara escaped in a stolen TARDIS, Ohila yelled that he was going against everything he ever believed in before leaving. The Doctor ultimately acknowledged that she was right. Ohila watched his departure with disgust, commenting that the Doctor was going to do what he does best: run. (TV: Hell Bent)
