Cave-In Rockfall

A jagged, unstable mass of limestone and debris from the tunnel collapse, burying the Doctor, Leela, and Idas beneath tons of rock. The rockfall consists of fist-sized fragments to house-sized boulders, shifting dangerously as K9’s blast clears a jagged passage upward. Dust and powdered stone cling to every surface, coating the trio’s coats and the droid’s metal casing alike.

K9 blasts companions free from rockfall

The unstable mass of jagged limestone and debris had completely buried the Doctor, Leela, and Idas under tons of rock, now violently dislodged by K9’s blast. The rockfall shifts from a death trap into a chaotic passageway as boulders tumble and dust fills the air, endangering the group even as it creates an escape route.

Before: Massive, immovable barrier of limestone and rubble completely entombing the trapped trio beneath tons of rock, with ongoing groaning and shifting indicating imminent further collapse.
After: Partially cleared and destabilized, becoming a jagged tunnel filled with falling debris and swirling dust, posing fresh but navigable dangers.

Before: Stable albeit weakened rock formations, previously braced mining ducts
After: Shifting rubble blocking lower tunnel, newly unstable debris pile
