Some doors don't lead anywhere.Others lead to the end.When reality fractures beyond containment, Black Door Operations is deployed.Operating above governments, outside laws, and beneath public knowledge, Black Door Operations investigates breaches that threaten not just lives-but existence itself. Doors that open where no doors should exist. Signals that predict extinction events before they occur. Objects and entities that don't belong to any known universe.The Eschaton Protocol is invoked only when containment has failed.Inside these classified case files are leaked reports of escalation-level anomalies: - Portals that rewrite causality- Thresholds that collapse timelines- Signals that map humanity's extinction- Operations that were never meant to be acknowledgedEvery chapter documents a mission that crossed the line from anomaly response into end-of-reality triage. Some doors were sealed. Others were destroyed. A few... are still open.This is not fiction meant to comfort.This is a record of what happens when the last safeguards fail.If this book exists, it means the protocol has already begun.
