Ultritium Residue

A fine, radioactive particulate clinging to ruptured hull plating and scattered wreckage—appears as an anomalous sensor signature rather than a clearly visible substance. Geordi's VISOR isolates it as a concentrated trace: microscopic grains and thin films embedded in fractures, producing a distinct radiation spike on readouts. Teams treat it as hazardous contamination, forcing sensor-led handling, quarantine procedures, and rapid evacuation during the storm.

Purpose

Acts as a forensic tracer and hazardous contamination marker used to identify deliberate destruction of the craft and to signal biohazard precautions for recovery teams.

Significance

Provides incontrovertible proof the Romulan wreck was sabotaged, converts a wreck-search into a political flashpoint, precipitates immediate evacuation and containment actions, and propels Geordi's isolated survival arc and the away team's moral/diplomatic crisis.

Worf Secures Patahk — Geordi Falls into the Storm

Ultritium residue is detected via Geordi's VISOR, functioning as the scientific trace linking the wreck to an explosive; it drives the team's hypothesis and justifies heightened caution and phaser readiness.

Before: Present in thin traces on ruptured hull plating and debris, detectable only by augmented sensors.

After: Remains attached to wreckage and continues to be a hazardous forensic clue for the team to catalog and quarantine.

Wreckage, Ultri-treachery, and the Pit

Ultritium residue appears on Geordi's VISOR readouts as concentrated traces on wreckage fractures — functioning narratively as the smoking-gun forensic clue that implies an explosive was used and elevates the incident from accident to probable sabotage.

Before: Embedded in fractures and surfaces of the wreckage, present as an anomalous sensor signature.

After: Remains on-site as forensic evidence being recorded and implicating foul play.
