Mathias’s reference is the Solarii Brotherhood cult from the Tomb Raider Game series Tomb Raider, also known as Lara Croft: Tomb Raider is a media franchise that originated with an action-adventure video game series created by British gaming company Core Design. The franchise focuses on fictional British archaeologist Lara Croft, who travels around the world searching for lost artifacts and infiltrating dangerous tombs and ruins. Gameplay generally focuses on the exploration of environments, solving puzzles, navigating hostile environments filled with traps, and fighting enemies. Additional media has been developed for the franchise in the form of film adaptations, comics and novels. The Solarii Brotherhood are the primary antagonists encountered in Tomb Raider as well as the majority of the humans residing on Yamatai. Very few members of the Solarii were referred to by name, mainly just Father Mathias, their evil master, Vladimir, the leader of a group of scavengers living in a mountainside village, and Vlad's brothers Boris, Nikolai, and Dmitri. They are organized like an armed cult. Mathias recruited as many as possible, choosing those who are physically strong, but not too smart, so they would fall in line and take orders. He drafted laws and a code for them to live by. They would need to prove their commitment to the queen, making them fall in line and believe. The Solarii built a city near the Queen's palace while Mathias searched for the key to unlocking her power and escaping the island.
