Cogline is a character in The Shannara Chronicles, based on the character of the same name from The Wishsong of Shannara. He is a man interested in the sciences of the Old World but who also knows how to use magic, as an ex-Druid.


After Wil and Amberle had left Eretria in Safehold, she was set upon by a group of Trolls. the Trolls dragged Eretria into a room where she fell onto her knees. She watched in horror as one of the Trolls removed their mask, but once she saw the man's face her eyes widened in shock and she gasped, "It's you."

The man in the mask turned out to be Cogline. He had promised Eretria's mother long ago that he would always protect her daughter.

A year after Cogline found Eretria in Safehold, the Rover girl is living in the ruins of San Francisco, scavenging Old World technology for Cogline with her girlfriend Lyria, and wondering why Wil and Amberle have not come looking for her.

Lyria and Eretria are out on a job together when they are found and chased after by Trolls. Eretria manages to kill two of the Trolls and leads her pursuers out to the ruins of the Golden Gate Bridge, where she is knocked into the water by a Troll. While under the waters of the bay, she sees a vision of Amberle, who tells her: "A new darkness is coming. You must find Wil. The fate of the world depends on it."

Eretria wakes up in one of San Francisco's old buildings, where she is being tended to by Lyria. Lyria says that she doesn't know how Eretria survived her fall of the bridge, but says that Eretria kept saying "Amberle" while she was unconscious. Despite Lyria telling her to rest, Eretria goes to speak to Cogline, and she tells Cogline about her vision. Cogline is unmoved, and urges her to let go of Wil and Amberle. It becomes clear that Eretria does not know that Amberle has become the Ellcrys, and that she believes that Wil and Amberle are living happily in Arborlon.

Later, Lyria reveals a secret to her girlfriend: Cogline has been lying to Eretria. According to Lyria, Cogline told everyone in his group except for Eretria that people may be looking for her, and he ordered his people to prevent anyone from ever finding Eretria.

Some time later, some people came to Cogline and said that "the Eretria problem" had been taken care of. Lyria, who witnessed this, said they gave Cogline an item as proof that the problem had been taken care of, and that although she didn't see what that item was, Cogline must still be holding onto it.

Lyria and Eretria go search Cogline’s belongings, and eventually Eretria finds Wil's stone pendant. They are caught by Cogline, who reveals to Eretria that Wil searched for her for months and that he prevented Wil from finding Eretria because a scion of Shannara would only end up hurting her. He points out that he had promised Eretria's mother that he would guard her with his life, and that after losing Eretria twenty years ago, presumably to Cephelo and his Rovers, he was not about to make that mistake again. However, Eretria counters by saying that it wasn't his choice to make.

Despite Cogline's protests, Eretria and Lyria leave Cogline and his people and head out to Arborlon. They are caught by Rovers while traversing Rover territory.

Changes made for the TV Adaptation

  • Cogline is a character in The Wishsong of Shannara and therefore never meets Eretria, who is a character in The Elfstones of Shannara.
  • In the novels, Cogline is extremely old and has episodes of madness, though they lessened towards the end of his life, during the time of the Druid Walker Boh. In the TV series Cogline is much younger, though still old, and his mental faculties seem quite typical.


Cogline is a character in The Wishsong of Shannara, The Heritage of Shannara tetralogy, and First King of Shannara. Due to liberal use of the Druid sleep, he is the longest-living Druid in the history of the Four Lands, born before the First War of the Races and dying over 300 years after the Third War of the Races.


Cogline was once one of the Druids, but he had left the Order before Brona (as stated in the First King of Shannara). He still studied the old sciences vigorously though, and was a master of them. Cogline knew how to create "black powder", what is essentially gunpowder, and Cogline was the one who gave Bremen the recipe to create a metal stronger than iron, which was used for forging the Sword of Shannara. He later joined Brin Ohmsford and Rone Leah in the battle against the Mord Wraiths. He also instructed Walker Boh in the use of magic and his own science, and served as Allanon's messenger in the conflict with the Shadowen. He had lived in Hearthstone for the great majority of his life, although he spent the last months of his life in hidden Paranor as a wraith to escape Rimmer Dall until Walker Boh restored him along with the Druid Keep. Cogline was killed when he used his gunpowder at point-blank range to greatly weaken the Shadowen that was posing as Death, one of the Horsemen of the Apocalypse, saving Walker's life in the process. He was mortally wounded doing so, and after a few words to Walker, he died.
