Object
Cavern/Tunnel Rockfall Debris
Rocks and debris from the cavern ledge collapse—triggered by Antodus's fatal scuffle with Ganatus—pile across the tunnel, blocking the group's escape route and injuring Ganatus. This rockfall occurs in two distinct but narratively connected locations: (1) the cavern ledge (Episode 10) where Ian and Barbara clear debris to expose a concealed passage beneath rusted pipes, and (2) the tunnel (Episode 11) where Ian and Kristas remove debris to reveal a hidden passage. The debris serves as a narrative barrier that forces the group to adapt, uncovering hope amid despair.
