Protocol Chimera: The Last Creature Bureau's Most Controversial Containment Policy Revealed

The mandate of the Last Creature Bureau (LCB) is simple, brutal, and absolute: contain the ontological threats that slip through the cracks of reality. For centuries, agents—often called Keepers or Splicers—have operated in the shadows of the Veil, utilizing arcane science and prohibitive technology to neutralize or sequester entities designated Alpha-Class and beyond. Yet, even within the Bureau’s morally grey hierarchy, one operational doctrine stands as a permanent scar on its institutional soul: Protocol Chimera.

Protocol Chimera is not merely a containment procedure; it is an existential compromise. Instituted following the disastrous ‘Silent Scourge’ event of 1888 (a catastrophic incursion traced back to the unregulated hybridization of Aetheric and Terrestrial matter), Chimera fundamentally shifted the LCB’s focus from preservation to controlled obliteration when containment integrity fails or becomes too resource-intensive. It dictates that certain highly volatile, reality-warping entities—those designated 'Chimeras'—cannot be safely held within established LCB Sanctuaries. Instead, they must be stabilized long enough for a voluntary, or enforced, ontological fusion.

The controversy stems from the core mechanism: the forced assimilation of a sentient, high-level Keeper or field operative into the containment matrix itself. The operative, willingly or under duress from the Directorate, becomes the living anchor, the necessary sacrifice that binds the runaway entity into a temporary, localized stasis field, often resulting in the complete erasure of the Keeper’s own existence from the timeline, leaving only fragmented echoes in the surviving personnel’s memory banks.

The Genesis of Necessary Atrocity: The Silent Scourge and Director Thorne

The implementation of Protocol Chimera is inextricably linked to the tenure of Director Elias Thorne, a figure whose legacy is perpetually debated in the hidden archives beneath the Obsidian Spire. Thorne, a brilliant but ruthlessly pragmatic Xenobiologist, rose to prominence during the late 19th-century expansion of LCB operations into the shifting territories known as the Umbral Fringes.

The Silent Scourge, where an entity known only as the ‘Unwoven Composer’ breached the primary containment wards of Sector 7 (now a permanently quarantined zone in the Carpathian foothills), resulted in the loss of three full enforcement battalions and the temporary collapse of local spacetime causality. Thorne argued before the High Council that conventional methods—the use of Null-Rods or temporal stasis fields—were insufficient against entities whose very nature defied established physics.

"Containment, in these extreme cases," Thorne is recorded as stating in the surviving audio logs, "is merely delayed failure. We must engineer a terminal paradox. We make the lock and the key the same object, and that object must be something the entity cannot digest without destroying itself."

Protocol Chimera became that engineered paradox. The first documented use involved Keeper Valerius Kaine, an elite Splicer renowned for his mastery over dimensional phasing. Kaine, knowing the fate awaiting him, was merged with the Unwoven Composer just as it began its final, reality-shredding broadcast. Kaine’s sacrifice stabilized the breach, but the cost was absolute. All records of Keeper Kaine, save for a single, recurring nightmare reported by his direct superior, were excised. This set the terrifying precedent: to save the world from a true Chimera, a Keeper must become an un-person.

The Keeper Caste and the Burden of Option Zero

For modern LCB personnel, Protocol Chimera represents the ultimate ‘Option Zero’—the final failsafe that every agent trains for but prays never to activate. The selection process for a Chimera anchor is heavily scrutinized. Candidates must possess an extremely rare neurological signature, often involving high levels of latent psionic energy or unique genetic markers that allow for a more stable, if agonizing, ontological integration.

This has led to the rise of specialized, often isolated, LCB units dedicated solely to identifying and cultivating potential Chimera anchors—the ‘Vessel Divisions.’ These divisions operate under intense secrecy, even from most field Keepers. Whispers suggest that certain high-ranking LCB officials intentionally expose nascent agents with favorable markers to controlled, low-level reality distortions, effectively 'priming' them for potential future use under Protocol Chimera. This proactive breeding or cultivation of human sacrifice fuels the ethical firestorm surrounding the Bureau. Are they Keepers, or are they highly specialized, expendable biological components destined for consumption by the very threats they are sworn to fight?

The Bureau maintains that the protocol is voluntary, signed off by the operative during initial induction into the most sensitive tiers of service. However, the definition of ‘voluntary’ when dealing with beings who understand the sheer scale of existential horror the LCB faces is highly debatable. A newly initiated Keeper, terrified by their first glimpse beyond the Veil, might sign anything to feel safe, only to realize years later that their signature has condemned them to a horrifying fate should a creature like the 'Void Weaver of Cygnus-X1' ever breach the Outer Shell.

Protocol Chimera ensures the continued existence of the known universe, but it does so at the expense of the souls of its supposed protectors. It is the ultimate expression of the LCB’s bleak philosophy: survival demands unimaginable impurity.

The Directorate is currently reviewing the containment status of Entity 44-Delta, rumored to possess self-replicating ontological anchors. Will the next crisis trigger the activation of Protocol Chimera once more, and which promising young Keeper will be chosen to anchor the paradox?
