This article contains plot details from the latest books.
For thousands of years, the Council reigned supreme. They were the wisest, most talented members of the elvin society, working together for the greater good. But in the past few decades, humans had developed weapons powerful enough to destroy the planet. Therefore, sixty years ago, a measure was brought before the Council to create a new Sanctuary specifically for humans.
The supporters of the initiative were angry with the Council. Some called for members to resign. There were threats to go ahead with the plan. The Council did not regard the threats. The human's thoughts were suddenly turned to initiating with a war against elves, because, not known by the councillors and the public at the time, the Neverseen had been kidnapping humans for experimentation. The councillors decided the humans had turned on the elves, and forbade any human contact, not knowing the human's had a perfectly logical reason to attack.They recruited Telepaths to keep their minds open for any suspicious activity going around in human thoughts. All talk of rebellion vanished, and the Council was satisfied.
However, the supporters of the initiative moved underground, and some of the more aggressive ones formed the rebel group now known as the Neverseen. The others formed the Black Swan.
The Neverseen wear a patch on their cloaks and an armband underneath, both with their symbol on it. The symbol is a white circle with a white eye in the center. This symbol has been in some of Sophie's nightmares.
"But I won't be silenced! Because the old ways are failing—and have been failing for centuries. This world doesn't need diplomacy. It needs quick, decisive leadership from someone who offers actual solutions. Someone not afraid of making the hard choices. Someone willing to make changes."
Fintan Pyren is the leader of the Neverseen and a powerful Pyrokinetic. He knows how to spark Everblaze and he was the first Pyrokinetic to be able to do so. He was a former member of the Council before the discrimination he faced because of his ability drove him away from his noble duties and led him to become a rebel.
Brant was the Pyrokinetic who burned Sophie and set the fire that had killed Jolie. He was trained by Fintan to spark Everblaze. In Lodestar, his skull was crushed into gray matter by a falling huge chunk of the ceiling after he was shoved by Mr. Forkle, in the crumbling remnants of Lumenaria.
Gisela is a polyglot and one of the many Neverseen members who tried to kidnap Silveny. Keefe Sencen had thrown a goblin throwing star at her, giving her a scar at the end of Book 2. She is the one who developed the Lodestar Initiative and was one of the leaders of the Neverseen until Fintan captures her into an ogre prison and tortured her using ogre methods, throwing her off the leadership podium and rearranging the hierarchy of the Neverseen. As of Lodestar, she has escaped from the prison, and she demands Keefe not to be affiliated with the Neverseen even though she was the one who dragged him into the organization in the first place. She was believed to have killed Cyrah Endal until it was disproven.
Alvar is revealed to be part of the Neverseen at the end of Book 4. He was one of the youngest to enlist, and he is also the one who had spied on Sophie when she was just five and still in the Forbidden Cities. But in Nightfall he was found in Lady Gisela's nightfall bound and beaten and was sedated with a powerful drug called soporidine. Alden, Fitz, Keefe, and Sophie went to his cell with the antidote to wake him up upon which Alvar was in a frantic state and finished the book with one of Shannon Messenger's famous cliffhangers saying "Who's Alvar?"
