A reality-ending paradox forces two lovers to become a Symbiotic Axiom, whose victory will heal their world-but sever the final like to Earth FOREVER. A wedding that will redefine reality begins with a single, defiant kiss. As Adæa Tel-Lynx and Vex Volkov-Rhenderon's love becomes a celebrated "proclamation" for a new generation, their mothers, the four Queens of Kremøtoa, are shattered by a terrible secret. While they are immortal, Adæa is not-and they are fated to endure the "longest goodbye" as they watch their daughter age and die. As the Queens grapple with this devastating prophecy, their guardian AI-Kløak-initiates a secret, deep-kernel query labeled the "Lynx Ascension Protocol" to find a way to defy the very laws of their world and grant Adæa the gift of forever. Before their search can bear fruit, a new cataclysm begins. The very fabric of their world is "fraying" as Nividia Rhenderon the Render-Witch arrives in terror, her own core code "un-writing itself". The cause is the Eschaton Protocol, an ancient 700-year-old "paradox engine" designed to consume logic itself. As the Queens are paralyzed by a "terrible calculus", the only solution becomes clear: Adæa-"the Composer"- must heal the paradox with her song, while Vex-"the Code"-must navigate its impossible logic. The two brides-to-be must descend into a living hell of corrupted data to save their world, armed only with their unique bond and the spectral, intervening sacrifice of a long-dead guardian. A triumphant wedding becomes a reality-altering event. As Adæa and Vex exchange their vows, the System itself acts. Recognizing their union as a "Critical_Stabilizing_Component", it rewrites the laws of existence and grants them both immortality. But this victory comes at an unthinkable price. Fixing the paradox severs the anchor to Earth. In the final, chaotic seconds, Kenji and Samantha attempt a desperate, one-way transfer. Kenji fuses with the AI Kløak, becoming a ghost in the shell of a ghost, while Samantha...vanishes. The search returns NULL, shattering the Queens with a new grief, unknown to them that she isn't gone, she's just...not Samantha Takahashi anymore. The Kremøtoa Codex is an adult science fantasy series intended for mature audiences. This book contains positive representations of LGBTQ+ relationships (both polyamorous and monogamous) and loving portrayals of neurodivergence (synesthesia and OCPD). However, this volume deals heavily with themes of existential crises (including the concepts of one's reality as a "prison" and the literal "un-writing" of a consciousness), profound psychological trauma (including the complete loss of a core identity), and overwhelming grief (such as parents witnessing the fiery death of their children). It contains scenes of violence, cosmic horror, psychological torment, bigotry, and a chapter featuring consensual, on-page sexual content. Reader discretion is heavily advised.
