Pelagia Themis

Pelagia Themis is a High Oracle of the Oracular Order and a minor character who appears in The Return of Daud.

Biography
As High Oracle, Pelagia's word was essentially law, holding as much power as the High Overseer, second only to the rulers of the Empire. She was dedicated wholeheartedly to the cause of the Abbey of the Everyman and willing to go to severe measures to protect it. This includes risking the safety of her own followers if necessary. She held the position of High Oracle as far back as during the Rat Plague.

The Return of Daud
In 1851, prior to the events of Dishonored 2, Pelagia Themis suspected an outside heretical force had been trying to twist the Prophecies of the Order to its own end. Fearful that the reports sent to High Overseer Yul Khulan were being corrupted, she decided to take action.

Traveling to the Order's Baleton Chapel, Pelagia set into motion a plan to test her theory. Using Sister Kara, a young member of the Order, as bait, Pelagia hoped to get some insight into the nature of the unknown entity. During the Ritual of Prophecy Pelagia's plan worked to the point that the Ritual was literally killing the young Sister. In an effort to remove the stain of the heresy, the High Oracle almost killed the young girl but was stopped at the last moment by Sister Hathena.

The Veiled Terror
Although the High Oracle does not appear in Dishonored: The Veiled Terror, Pelagia was rumored to have been killed by or on orders of the successor to High Overseer Khulan along with dozens of high-ranking Overseer and Oracular Sisters, in the aftermath of the severance of the Outsider from the Void. The only certainty is that neither she nor the High Overseer were seen in public after the fall of the Outsider.

Trivia

 * Despite her seeming amoral attitude, the High Oracle does seem to have the Order's best intentions at heart, going so far as to realize the mistake she made with Sister Kara and thanking Sister Hathena for her interference rather than reprimand her.
