Joren Pilot

Joren Pilot is a secondary character in The Boy from the Bunker and is portrayed by Giancarlo Esposito in the books. He is a Sovereign of Basilisk in Season 1 alongside Eryx Riverly (and Elijah Scout (who is deceased)) and has been a long-time guardian and parental figure to Sol Riverly amidst her fluctuating relationship with her father.

Joren doesn't have any mentioned biological family in the books, however, he is seen as the guardian/father figure to Sol Riverly through her unstable relationship with Eryx Riverly in the early seasons, and maintains his support and mentoring over her after Eryx is killed. He is also listed as Dreea Taven's Nominated as he dedicated himself to getting her ready to become a Sovereign when she was younger after noticing her potential. He is also a mentor figure to Kodiak Zora and Wynn Bell through their time as Sovereigns and helped them to navigate through their leadership after Sol's departure in Season 5.

Prior to Season 1:

Joren became a Sovereign alongside Eryx Riverly and Elijah Scout, both of whom he had trained with for several years before their leadership. Joren was good friends with Moria Riverly (Eryx's wife, Sol's mother) as he worked closely with her husband, Eryx, and soon became a trusted confidant of hers. When Moira confided in him about her suspicions of Eryx having an affair with Zara Beckett and her plans to confront him, Joren proceeded to take Sol out of camp to protect her from Eryx's wrath, only to come back and learn that Moira was missing. When Joren approached Eryx, he learned that in the heat of their argument, Moira had been killed. Wanting to protect Sol first and foremost, Joren forced Eryx into coming up with a cover story for Sol about her mother's absence (as she as too young to know the harsh truth), leading her to believe that she had taken shelter in a nearby bunker. After Moira's death, Joren declared to Eryx that he would become a legal guardian of Sol so that he could protect her or else he would reveal to the people of Basilisk the truth about what had happened to Moira.
