Orcas

Orcas appear only briefly, but their presence and absence help mark the changing state of the ocean. During the crisis they are among the dangers Weaver does not encounter on her descent; after the attacks stop, the wider whale population returns to its ordinary routine. The novel offers no individual orca or account of its motives, keeping these animals within a larger ecological change rather than giving them a separate character arc.

Presence in the Crisis

On a descent in the Deepflight, Karen Weaver travels through nearly a kilometre of water. For ten minutes she watches the lighted darkness ahead, relying on the submersible’s computer for information the view cannot provide. Her path remains clear of both orcas and Yrr. The scene records their absence rather than an encounter: the descent is not interrupted by an attack, and no orca behavior is described.

That distinction matters in the novel’s wider crisis, where marine life has become a source of danger. The passage places orcas alongside the Yrr as threats from which Weaver’s route happens to be free, but it does not identify the two as the same kind of being or explain any direct connection between them.

The Attacks Cease

After the USS Independence sinks, the attacks halt soon afterward. Around the same time, the SOSUS arrays register Scratch signals audible across the ocean. A rescue team reaches the seamount to free Gerhard Bohrmann from his underwater cave and finds that the sharks have disappeared. The account then describes whales returning to their normal routine overnight; it does not single out orcas from the wider whale population.

The retreat extends beyond whales. Worms and swarms of jellyfish and other toxic creatures vanish, while crabs stop invading the coast. The oceanic pump gradually resumes functioning, the threat of an ice age recedes, and methane hydrates begin to stabilize. The text places the return of the whales within this broad reversal, without claiming that the orcas themselves caused it or specifying how they respond to the Scratch signals.

Narrative Significance

The orcas’ brief appearances make their absence carry weight. On Weaver’s descent, their nonappearance is one element of a temporarily clear passage; in the aftermath, the whales’ restored routine becomes part of a larger cessation of marine attacks. The narrative shifts from immediate danger to a sea that seems to be settling back into its former patterns, while leaving open whether the reprieve is permanent. Orcas therefore register the scale of the crisis indirectly: not through a detailed account of their own actions, but through the change in the ocean around them.
