The Yrr Enter the Sluice

A Breach at the Hull
The ship’s defenses fail
A Yrr mass forces its way through the sluice after Rubin urges the crew to collect it.
An orca enters the basin, transforming the experiment into a lethal attack.
The Well Deck Becomes a Battlefield

Crew and Scientists Scatter
Control is lost
Orcas and Yrr tentacles overwhelm the well deck while gunfire and the trapped submersible add to the chaos.
The vessel’s artificial containment system can no longer keep the attack outside.
The Ship Starts Flooding

A Warship Becomes a Wreck
Structural failure spreads
The blast ruptures compartments, flooding the ship and igniting further fires.
The crew’s evacuation is constrained by the vessel’s tilt and damaged systems.
The Final Escape

A Few Survivors Leave
Rescue through the rising water
Anawak and Crowe escape through the flooding vessel and reach a Zodiac as the Independence sinks.
Their survival depends on quick improvisation rather than the official evacuation plan.
The Yrr Are Left Unresolved

A Costly Failure
No victory is claimed
The Independence is lost, Li’s plan fails, and the survivors have no certainty about the Yrr’s next move.
The disaster reinforces the danger of treating ecological conflict as a conventional war.
