A father and his daughter observe the emergence of mysterious, animal-like oil rigs.

"Only the most violent post-return decommissioning could stop all this, only second deaths, from which the rigs did not come back again, kept them from where they wished to go, to drill. Once chosen, a place might be visited by any one of the wild rigs that walked out of the abyss. As if such locations had been decided collectively. UNPERU observed the nesting sites, more all the time, and kept track of the rigs themselves as best they could, of their behemoth grazing or wandering at the bottom of the world."
