It was then brought to 10th century Transylvania by Fenric. Fenric commanded him to follow the Vikings who had stolen the flask containing Fenric. It fed on them, turning many of them into Haemovores. It and the Haeamovores followed the Vikings, and after those were killed by the pirate Hemming, followed him to Maiden's Bay. Though Hemming and all his men were killed by the Ancient One, Hemming had buried the flask beneath St. Jude's Church, where they could not get it.
Eventually, in 1943, the Ancient One was awakened again by Fenric. It was used to control the Haemovores, which were used to attack the soldiers in the base. Using the poisons made by the nearby base, Fenric intended to pollute the world, causing the future that created the Haemovores. The Seventh Doctor was able to convince Ingiger to betray Fenric, convincing it that Fenric would not return him to his own time. The Ancient One killed both itself and Fenric by going into the isolation chamber with Fenric and releasing a poison. (TV: The Curse of Fenric)
- As Fenric has called his Wolves descendents of the Vikings, it is possible that before he mutated, if he was a human at all, Ingiger was a descendent of Vikings.
When Fenric recovered, the Ancient One was again used as his pawn. He was begged by the Doctor to release him from the chains that Fenric chained him in. He didn't do anything. He went on search for the Doctor, and found his son Hurmzid. Leading the hoards of Haemovores again Weyland's saxon, he was killed by a spear. (AUDIO: Gods and Monsters)
