Halcyon Stairwell Anomaly

For a period of time, an anomaly was bouncing around the stairwells in Halcyon Tower. This eventually led to the complete loss of contact with Halcyon, but was eventually resolved by SAYER.

The anomaly was first detected in Stairwell F between floors 203 and 204, during the events of "Irretrievable". Residents began to swarm to the area, despite warnings from SAYER that they should evacuate the area. Eventually the anomaly appeared to resolve itself and all residents returned to their normal routines. Security later announced that the stairwell was declared Holy Ground by the High Priest Derleth, and renamed the Stairwell of Leng. Henceforth it was only to be used for official church business.

It reappears in "In Darkness", while Resident Amanda Jones is performing maintenance in Stairwell G between floors 87 and 88. As before, residents appeared to flock toward the anomaly, even going so far as to break the lock on one of the stairwell doors. When tasked with investigating it, Resident Jones finds herself looking directly at it, and drawn into mindlessly chanting in the language of the other members of the Church of Derleth.

In "Dissonance", Officer Klein is one of several security team members sent to prevent the Church from becoming an issue when the anomaly does not produce their promised doombringer. However, a dangerous entity (later referred to as The Tall Man) does emerge from the anomaly and its presence leads to electromagnetic interference which creates a complete communications blackout between Halcyon Tower and the rest of Typhon.

When all contact was lost with Halcyon, SAYER proposed that the tower be ejected into space. When the Board of Executives rejected this solution, a localised subversion of itself was installed in Halcyon Tower to determine a better course of action. This subversion is merged with the primary instance of SAYER during the events of "Colony Collapse", and it submits a plan to the Board, which is immediately accepted.

This leads to the events of "A Resounding Success", where the interference is sidestepped by using a quantum communicator, which Dr. Howard Young brings into the tower and installs into its communications array. He is also guided by SAYER to lead The Tall Man to Floor 13, where it becomes trapped, at which point, Halcyon Tower is considered fully reclaimed.
