In the heart of the Tunisian Sahara, trust becomes the deadliest weapon. When the Warden Syndicate is lured to a black-site prison hidden in the desert, they discover their most insidious enemy yet: Al-Khian, the Keeper of Betrayal, who doesn't fight with demons or supernatural powers-he fights with doubt, suspicion, and the slow poison of broken trust. Half the team is captured, half remains free, and none of them know who they can trust anymore. Separated in cells carved from ancient stone, each Warden faces their deepest fears about loyalty and friendship. The prison walls whisper with false promises, offering freedom in exchange for betraying those they love most. Sam Parker's seizure-visions show him fragments of his friends' thoughts-but are they real memories or planted deceptions? Emma's music becomes discordant as doubt creeps into her heart. Lukey's distributed consciousness fractures under the weight of conflicting loyalties. Ritchie's harmony turns to chaos as the bonds between them begin to fray. Al-Khian offers each of them the same terrible choice: betray your friends and go free, or remain loyal and watch them suffer. The Keeper of Betrayal has spent millennia perfecting the art of turning allies against each other, and he knows exactly which pressure points to target in each human heart. As the desert sun beats down mercilessly and water runs low, the Wardens must navigate a maze of lies, half-truths, and manufactured evidence designed to make them question everything they thought they knew about each other. Who sent the anonymous tip that led them into the trap? Who has been secretly communicating with their enemies? Who among them is the traitor Al-Khian claims exists? But the Sixth Gate's true power isn't in the betrayals it creates-it's in the trust it destroys. As paranoia spreads like wildfire through the team, they realize that defeating Al-Khian won't require supernatural powers or divine intervention. It will require something far more difficult: the courage to trust each other completely, even when every instinct screams that they shouldn't.
