To the Lords of the Inquisition,

The following report contains highly sensitive intelligence regarding an unprecedented surge in activity among the cults of Slaanesh across the Imperium and in the Warp itself. The information herein must be acted upon with the utmost urgency.

Observed Phenomenon: "The Promise of Ecstasies"

Across numerous sectors, reports have surfaced of synchronized and violent celebratory outbreaks among Slaaneshi cults. These events are not isolated to hive cities or corrupted enclaves but are occurring in locations as diverse as industrial moons, penal colonies, and even Imperial Navy vessels. The cultists refer to this emerging phenomenon as The Promise of Ecstasies. This designation appears to be intentionally vague, a reflection of its likely psychic or metaphysical nature.

The specifics remain unclear, but all accounts suggest the anticipation of an apocalyptic servant or event tied directly to Slaanesh itself. Cults whisper of a presence, one they claim embodies perfection in suffering and ecstasy. The few captured cultists, though largely incoherent, describe visions of a figure—or force—capable of obliterating both the material and immaterial with its mere existence. This expectation has driven the faithful to new depths of depravity, with entire hive sectors lost to riots of self-mutilation, ecstatic violence, and ritualized defilement.

Warp-Based Indicators

Daemonic manifestations have intensified significantly. Reports from rogue psykers, sanctioned astropaths, and intercepted xenos signals suggest an unusual spike in activity within the Warp. Daemons aligned with Slaanesh, including greater entities, appear to be in states of exaltation. Sightings of Keeper of Secrets engaging in coordinated rituals have been confirmed. These are not battles or skirmishes but acts of celebration and communion, a rare and deeply disturbing development.

Warp-travel incidents, particularly among Eldar vessels, indicate the immaterium itself is thrumming with an alien joy. An intercepted Eldar communication references the "laughter of She Who Thirsts" as being unbearably loud. The implications of a heightened state of pleasure or satisfaction from Slaanesh must be considered a threat of the highest order.

Xenos Evidence: Craftworld Eldar

The Craftworld Eldar have reacted with profound horror to this phenomenon. Fragmentary intelligence acquired through interrogation of Eldar captives and divination rites conducted by sanctioned psykers suggests the Eldar perceive this as a precursor to disaster. They speak of an entity whose existence signifies Slaanesh's ascendancy to a state of unprecedented power.

A consistent detail in these accounts is the name "Mercy." This individual—or avatar—is described as a young girl, seemingly human in appearance, though undoubtedly touched by the Dark Prince. She is believed to be a favored servant, rewarded directly by Slaanesh. The Eldar describe her as a being of paradoxical innocence and malevolence, capable of corrupting entire worlds with her mere presence. If true, she represents not only a spiritual threat but a vector for material corruption on a scale not seen since the Horus Heresy.

Strategic Implications

Imperial Stability: If the Promise of Ecstasies manifests as cults predict, it could lead to widespread rebellion, corruption, and chaos within the Imperium. Daemonic Incursions: The heightened activity in the Warp suggests the potential for mass incursions, particularly if the forces of Slaanesh rally around this new entity. Xenos Interference: The Eldar's desperation to address this phenomenon may lead to unforeseen alliances or conflicts. They have been observed deploying strike forces to sectors with heightened cult activity, presumably in an effort to forestall whatever is occurring. Moral Threat: The existence of "Mercy" poses a profound challenge to Imperial dogma and morale. Her ability to embody corrupted innocence could unravel the faith of even the most devout.

Recommended Actions

Immediate Purge Operations in all sectors reporting cult activity linked to this phenomenon. Increased Monitoring of Warp Activity through astropathic networks and psychic wards to anticipate daemonic incursions. Covert Observation of Eldar Movements to gather intelligence on their understanding of this threat. Investigation into "Mercy" through any means necessary, including the deployment of dedicated Inquisitorial kill teams. If this figure is a physical entity, she must be neutralized at all costs.

Conclusion:
The signs are clear. Something is stirring within the shadow of She Who Thirsts, and its implications cannot be ignored. This Promise of Ecstasies threatens not only the material realm but the fabric of human faith and sanity itself. The Inquisition must act decisively and without hesitation.

For the Emperor,
Inquisitor Thalvar Kaedrin
