Tomb Raider: Definitive Edition | Gameplay walkthrough| Part 6 Lara, who is closest to Sam's position, tries to rescue her but is foiled by Mathias—revealed to be the leader of the Solarii—who orders her killed. Lara is saved by the intervention of a samurai dubbed "Oni" and taken to an ancient monastery in the mountains. Escaping again, Lara stumbles upon a ritual chamber, where she learns that a "fire ritual" was used to choose the Sun Queen's successor as part of a ceremony called the "Ascension." A terrified Sam manages to contact Lara and informs her that the Solarii intends to put her through the fire ritual, which will burn her to death if unsuccessful. Lara fights her way through the Solarii fortress with help from Grim, who is killed after the Solarii captures him. With Roth's help, Lara infiltrates the palace and witnesses Mathias putting Sam through the fire ritual. Lara tries to save Sam, but she is overpowered by Mathias and his men. Sam is not harmed by the flames, which are extinguished by a great wind, marking her as Himiko's rightful successor.
