Ingeborg the Firebrand (died December 875) was a Danish Roman Catholic abbess from Jorvik (York) and a Preost and Warden of Law of the Order of the Ancients during the late 9th century AD.
Biography[]
An angry priest once scrubbed Ingeborg's tongue with soap for spewing "heresies and lies." That day, Ingeborg learned that knowledge was power, controlled by the Catholic Church. She then rose through the Church hierarchy, but the Order of the Ancients offered her even more knowledge and thus more power.

Ingeborg in 875 AD
Ingeborg became one of "the Vault" Audun's lieutenants during the 870s AD, helping him to collect Christian texts from York Minster's rectory with the objective of burning them and erasing any views opposed to the Order's worship of the "ancients" (the pagan old gods). She had the Red Hand gang of brigands overrun the Minster and burn the Bishop to death after he decided to resign from his positions at the Minster due to his opposition to Ingeborg's sacrilegious burning of old Christian texts.
In 875 AD, she met the Viking warrior and Hidden Ones ally Eivor when she and Audun walked in on Eivor investigating the archives, and, when Eivor said that he was in York to hunt the Order of the Ancients, Ingeborg volunteered her help in any way she could. She told Eivor that she had her suspicions about the Order's activities at the rectory, where it was said that the bishop visited his priests under the cover of night. However, she secretly sent Red Hand brigands to the rectory to kill Eivor, but Eivor succeeded in assassinating all of them and discovered the Bishop's burnt body and a letter from the Bishop pointing Eivor to the Minster and Ingeborg's operation. There, Eivor assassinated a few guards and found piles of burning texts, and, from a vantage point, he saw Ingeborg push the priest Inguburh Graves into the bonfire after he protested her heresy.
Death[]

Ingeborg's death
Eivor, now certain that Ingeborg was "the Firebrand", jumped down from his vantage point as Ingeborg stood over the fire, and he shot her in the face with an arrow before swiping at her with his battle-axe. His axe lodged in her neck, and he then yanked it so that the mortally-wounded Ingeborg fell to the ground. Eivor then plunged his hidden blade into Ingeborg's chest, and, in her last moments, Ingeborg bragged about how one of "the four" was "theirs", which Eivor later discovered meant that one of Jorvik's four council members (Audun) was a member of the Order.
