Creeper attack on the main lock

The Creeper attack on the main lock turns an apparently contained breach into a crisis of both security and understanding: the creatures came through the structure from below, while the response to stop them killed a human officer. Recounted after the attack rather than staged as a continuous action scene, the event is pieced together through its casualties, the failure of the colony’s scans, and the unsettling possibility that the Creepers are taking metal from the dome for their own purposes.

Causes and Warning Signs

At a late-shift dinner in the cafeteria, survivors reckon with five deaths in one day. Groups of three or four speak in low voices, and the gathering turns to the familiar human habit of describing the dead as foolish, as if their mistakes could make the same fate seem avoidable. The scene establishes the attack’s communal cost without suggesting that those killed brought it upon themselves: the talk is a way for the living to manage fear, not an explanation of what happened.

Cat Chen, whose colleagues Gillian and Rob were among the dead, asks whether anyone detected the attackers before they struck. Berto Gomez had already told her that the patrols had not picked anything up. Nasha confirms that she had been scanning with visible and infrared sensors as well as ground-penetrating radar, and that her last pass had shown the area clear. Cat’s estimate is that her team could not have been exposed for more than thirty seconds at a time. The gap between those apparently clear checks and the breach makes the attack difficult to explain by ordinary surface surveillance.

Nasha offers a possible explanation, not a confirmed account: the Creepers approached the main lock from underneath, where radar could not see through granite. She wonders whether they are miners and whether their tunnels might reach directly beneath the dome. Cat’s glance toward the floor registers the immediate consequence of the suggestion: even a protected meal in the colony can feel precarious once the ground itself becomes an unknown route of approach.

The Breach and the Response

Mickey Barnes later explains the incident to Mickey8, who has heard a brief feed reporting four accidental deaths and one person missing, all outside the dome. Mickey corrects that account: one death was in the main lock, which had been put out of service after the incident. The lock was used as a murder hole against the Creepers, making the security response itself part of the event’s lethal aftermath.

The creatures had breached the decking. In Mickey’s account, they did not merely enter through an existing access point: they cut straight through the deck and began peeling it away. Mickey8 initially understands this as an animal attack and objects to using live plasma to kill animals. Mickey insists that the creatures had breached the structure, emphasizing the scale of the danger rather than treating them as ordinary wildlife. The disagreement turns on what the word “breached” means: the Creepers’ actions were directed at the colony’s built environment, and the damage appeared deliberate enough to suggest a purpose beyond getting inside.

The defenders vented plasma into the lock to kill the intruders. The same action roasted Gallaher, a Security officer whom Mickey describes as mostly dead already. The episode therefore resists a clean division between protective force and collateral harm: the lock was used to stop the Creepers, but the method killed someone on the human side as well. Mickey8’s initial disbelief underscores how difficult it is to grasp the incident from a short report; the explanation changes the apparent story from several disconnected accidents into a violent breach and a response that inflicted another death.

Casualties and Unresolved Questions

The attack is followed by a count of five deaths, including Gillian and Rob, whose loss is personal to Cat, and Gallaher, who died in the plasma-filled lock. The available account does not identify all five victims or resolve the missing-person report that Mickey8 saw. It does establish why the colony treats the day as frightening: the dead cannot be explained away as a single group caught outside, since the main lock itself became a place of fatal danger.

The cause of the Creepers’ sudden appearance also remains unsettled. Nasha’s scans had shown the patrol area clear, but she qualifies the limits of those scans: ground-penetrating radar cannot see through granite. Her underground-tunnel theory can account for how the creatures avoided detection, yet it does not prove their route or explain the full extent of their behavior. Likewise, Mickey’s suggestion that they may need the colony’s metal because the planet is metal-poor remains conjecture. The creatures’ apparent removal of decking hints at resource gathering, but neither their objective nor what they intend to do with the material is established in this account.

Aftermath and Significance

The immediate consequences are practical and psychological. The main lock is no longer in service, while the cafeteria’s subdued conversations and Cat’s fear of tunnels show how the breach reaches beyond the damaged structure. Nasha tries to lighten the moment by pointing out that they have top-level sleeping racks; the joke offers little security against a threat imagined as able to move beneath the floor. The exchange preserves the survivors’ uneasy mixture of humor, grief, and vigilance.

As a turning point in the colony’s understanding of the Creepers, the attack joins an invisible approach to an unmistakable act of structural damage. The first account offers no warning on the scans; the later conversation supplies the breached decking and plasma response; and the dinner conversation leaves the means of approach unresolved. That progression matters: the colony can count its losses and close the main lock, but it cannot yet say where the attackers came from or why they were taking metal. The event thus leaves the survivors with more than a security failure. It forces them to consider that the creatures may have their own purposes within the human settlement’s built environment.
