Welcome, everyone, to The Laundry Files actual play. I'm Dakota Reynolds, your Keeper for today's mission. We're exploring a classified scientific endeavor that officially doesn't exist—the CERN Gravitational Observatory, callsign "Charybdis." Our setting is the year 2024, deep in the vacuum of space, three million kilometers from Earth, in orbit around the binary black hole system designated GW-2023-7749. The Laundry has detected anomalous mathematical patterns in the radiation signatures. What was supposed to be humanity's greatest scientific achievement has become something far more sinister. Two weeks ago, the primary research vessel went silent. You've been dispatched as field agents to investigate and, if possible, recover the research data before the cosmic horror consuming that station consumes everything it touches. Your characters are uniquely qualified—you operate at the intersection of knowledge and the occult.

Welcome to tonight's Delta Green operation. The year is 2081, and humanity has finally managed to recover the Event Horizon, a legendary deep space research vessel that disappeared during its maiden voyage in 2047. For 34 years, the vessel was considered lost, until a routine asteroid mining operation in the Kuiper Belt discovered it drifting silently, its systems offline but hull largely intact. The Event Horizon was supposed to be mankind's first step into interstellar travel, featuring an experimental gravity drive designed to create an artificial black hole, folding space and allowing instantaneous travel between points in the universe. When it vanished during its maiden voyage, most assumed some catastrophic engineering failure. Now that it's been found, Delta Green has taken interest - particularly in the disturbing distress signal that was finally deciphered. In the garbled message, the ship's captain, Dr. William Weir, can be heard saying, "Liberate me... ex inferis." Save me... from hell. Your team of forensic specialists has been assembled to investigate the recovered vessel before it's brought back to Earth. You'll be boarding from the USSC Goliath, a military research vessel currently holding the Event Horizon in orbit around Neptune.

Welcome investigators to our Call of Cthulhu adventure set in the year 2047. Tonight, we'll be exploring the infamous Event Horizon spacecraft, which disappeared during its maiden voyage in 2040 before mysteriously reappearing in Neptune's orbit seven years later with no trace of its crew. Your characters have been sent as part of a specialized salvage and investigation team to determine what happened to the vessel and its experimental gravity drive.

Welcome to our Trail of Cthulhu game set in the year 2137. Humanity has established colonies on the Moon and Mars, and exploration of the outer solar system is well underway. Europa, Jupiter's icy moon, has become the location of mankind's most secure detention facility - the ESV Tartarus, a maximum-security prison ship housing the worst criminals from Earth. Our investigators are a team of antiquarian booksellers who have been hired by the Interplanetary Corrections Authority to appraise a collection of rare books discovered in a smuggling operation to the ship.

Welcome to tonight's Delta Green operation. The year is 2039, and humanity has expanded its reach into the solar system. Tonight, we find ourselves aboard the Terminus Alpha, a prison transport vessel bound for Europa. The ship carries 200 of Earth's most dangerous criminals destined for the Hades Detention Facility being constructed beneath Europa's ice. Our agents have been dispatched following reports of... unusual incidents.

Welcome, investigators, to our tale of cosmic horror. The year is 2137, and humanity has expanded its reach into the far corners of our galaxy. Our story begins on Proxima Centauri b, a once-thriving human colony that has been condemned due to its unstable orbit. You see, Proxima Centauri b has been caught in the gravitational pull of Sagittarius A*, the supermassive black hole at the center of our Milky Way. Scientists calculate that the planet has roughly seven Earth days before it crosses the event horizon. All colonists were evacuated months ago... or so everyone thought. Your team of specialists has been hastily assembled and sent to retrieve valuable research data from the Hawthorne Research Station, but upon arrival, you've discovered disturbing signs that not everyone left the doomed world. The radiation levels are rising, and the very fabric of reality seems to be stretching thin as gravitational forces warp space-time around you.

Welcome everyone to tonight's session of Call of Cthulhu. It's 1955, and the First Indochina War has recently ended with the Geneva Accords partitioning Vietnam. The French colonial presence is withdrawing, leaving behind decades of occupation and cultural disruption. Our investigators are part of an international academic expedition, ostensibly studying the aftermath of colonialism and collecting artifacts before they're lost to time. The North Vietnamese government has granted limited access to certain historical sites, but they're watching you closely.

Welcome to tonight's session of Call of Cthulhu. The year is 1925, and our story takes us to Northern China, where strange reports have emerged from the ancient Yungang Grottoes. Local workers have gone missing, and unusual botanical specimens have been discovered growing within the sacred Buddhist caves. Miskatonic University has dispatched a team of specialists to investigate.
