After Melik Ismail's rescue, Gümüştekin faces a decisive battle, relying on an alliance with Mila to survive. Saladin targets Beytülahzan Castle, a crucial threat on the path to Jerusalem, using underground tactics rather than traditional warfare. King Baldwin, empowered by the discovery of the Holy Grail, commands absolute power and unites forces to defend against Saladin, delaying Guy's aspirations to become king. As Ayyubid forces dig tunnels to bypass Templar defenses, both sides prepare for an intense struggle over Beytülahzan. The outcome of this conflict remains uncertain.
