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.
